DIGITAL CONTROL INCORPORATED 8 DigiTrak® F2™ Operator’s Manual Notes

DIGITAL CONTROL INCORPORATED DigiTrak® F2™ Operator’s Manual 9 Introduction DigiTrak F2 Locating System The DigiTrak F2 Locating System is used during horizontal directional drilling (HDD) operations to locate and track a transmitter installed in the drill head. The system consists of a handheld receiver, a transmitter, a remote display with battery or cable power options, a battery charger system, and three rechargeable lithium-ion battery packs used for powering the receiver and remote. Locating is streamlined using the F2 receiver’s graphic display and menu system. The real-time graphics guide you in positioning a target in a box on the display window to help locate the transmitter. In addition to the basic locating capabilities of directional tracking and depth, the F2 system includes the advanced features of predicted depth, off-track locating, and Target Steering to navigate the drill head easily and accurately even when obstacles prevent walkover tracking. This manual provides information on each F2 system component—the receiver, transmitter, remote display, and battery charger—in separate sections following this Introduction. These sections are followed by the Locating section, which explains important locating terms and gives step-by-step locating instructions. FX Transmitter FXL Transmitter Battery Charger Receiver Remote Display Rechargeable Battery Pack

Introduction 10 DigiTrak® F2™ Operator’s Manual The F2 system is programmed to comply with varying global operating requirements. The receiver’s regional designation number must match that of the transmitter for proper communication (see figure showing startup screen in Receiver section and photo of FX transmitter in Transmitter section). Also, the receiver’s telemetry frequency designation must match that of the remote display (see photos of serial number labels in Receiver and Remote Display sections). Appendix A presents the F2 system’s power, environmental, and maintenance requirements. Appendix B explains how to calculate depth when the transmitter is deep (greater than 15 ft or 4.5 m) and/or at a steep pitch (greater than ±30% or ±17°). Appendix C explains how to calculate the transmitter depth based on the distance between the front and rear locate points and the pitch of the transmitter.

DIGITAL CONTROL INCORPORATED DigiTrak® F2™ Operator’s Manual 11 Receiver F2 Receiver – Side and Back Views General Description The F2 receiver is a handheld unit used for locating and tracking an F2 transmitter. The receiver converts signals from the transmitter and displays the following information: depth, pitch, roll, temperature, and battery level. The F2 receiver can send this same information to the remote display at the drill rig. To meet regional requirements and for proper communication, the telemetry frequency designation for the receiver must match that for the remote display. The telemetry frequency designation is identified on the receiver’s serial number label, which is located inside the battery compartment (see photo). It must match one of those listed on the remote display’s serial number label located on the back of the unit (see "General Description" in Remote Display section). The receiver and transmitter must also be able to communicate properly in different global regions. A regional designation number is provided in the receiver’s software (see figure titled "Receiver Startup Screen" later in this section).

NOTE: The calibration will fail when the signal from the transmitter is above 950 points or below 300 points.

Receiver 24 DigiTrak® F2™ Operator’s Manual 2 Point Calibration (In Ground) The 2PT CAL option allows you to calibrate the receiver to the transmitter when it is in the ground. Two- point calibration is rarely needed. If you must calibrate with the transmitter in the ground, use this procedure with caution. To start the 2-point calibration procedure, select 2PT CAL from the calibration menu. You will see the following screen. First Point, 2PT CAL This screen instructs you to put the receiver on the ground directly above the transmitter, preferably with the transmitter nearly level. (See the Locating section for instructions on how to position the receiver directly over the transmitter.) The flashing trigger symbol at the top of the screen indicates that a trigger click is needed to obtain the first point for the 2-point calibration. Click the trigger, and the display will count down from 5 to 0 while the receiver records the first calibration point. If the signal strength from the transmitter is within the tolerable range (300–950 points), a checkmark will display on the screen and you will hear the confirmation signal indicating that the first calibration point has been successfully recorded. Then the second 2PT CAL screen appears.

Receiver DigiTrak® F2™ Operator’s Manual 25 Second Point, 2PT CAL To record the second calibration point, lift the receiver 3 ft (1 m) directly up, keeping it level, and click the trigger. The display will count down from 5 to 0. Do not move the receiver while the display is counting down. NOTE: The second point screen will display even if the first point fails. After the second point is recorded, an Χ will appear on the screen and you will hear the failure signal. You must click the trigger to continue and restart the calibration procedure. You will see the following screen and hear the confirmation signal when the calibration is complete. Successful 2PT CAL Screen

Receiver 26 DigiTrak® F2™ Operator’s Manual After the 2-point calibration procedure has passed, verify the distance between the two calibration points by taking depth measurements at the first point and the second point and then determining the difference between the two values. The difference should be 3 ft ± 2 in. (1 m ± 5 cm). Repeat these measurements several times as you continue drilling to verify that the depth remains valid as the pitch of the transmitter changes. If the 2-point calibration procedure fails, a failure screen will appear, and you will hear the failure signal. The 2-point calibration will fail if the signal strength is too high or too low or if the procedure is done improperly, for example, if the receiver is not raised high enough. The 2-point calibration will also fail if the receiver calculates a depth that is not legitimate for the range of the transmitter. If the calibration fails, verify the setup and signal from the transmitter at both calibration points to make sure they are stable and within range. If the signal strength is too high at the first point (>950), lift the receiver until the signal strength is 950 or less, and then take the first calibration point. Lift the receiver 3 ft (1 m) higher to record the second point. If the signal strength is less than 300 at either point, you will have to pull back until the signal strength is greater than 300 points or trip out to do an above-ground calibration (1-point calibration).

DIGITAL CONTROL INCORPORATED DigiTrak® F2™ Operator’s Manual 35 Transmitter Types of F2 Transmitters DCI manufactures two different battery-operated transmitters for use with the F2 system: the long-range FX transmitter and the extended-range FXL transmitter. Both transmit a signal at 12 kHz and provide pitch readings in 0.1% or 0.1° increments (from 0% to 100% or 0° to 45°). The transmitter fits inside the drill housing and emits electromagnetic signals that the F2 receiver “hears”. The receiver converts these signals to display the drill head location, position, and heading on the receiver and remote display screens. An index slot at the front end assists in proper alignment of the transmitter in the housing. The transmitter and receiver must have matching regional designation numbers to ensure that they comply with local operating requirements. The transmitter’s regional designation number is located inside the globe symbol ( ) near the serial number on the transmitter’s battery compartment, as shown in the photo below. This number must match that of your receiver for proper communication (see startup screen figure under “Turning on the Receiver” in the Receiver section.) Long-Range FX Transmitter The long-range FX transmitter provides a depth range of approximately 65 ft (19.8 m). It measures 15 in. (38.1 cm) long and 1.25 in. (3.175 cm) in diameter. Extended-Range FXL Transmitter The extended-range FXL transmitter provides a depth range of approximately 85 ft (25.9 m). It measures 19 in. (48.3 cm) long and 1.25 in. (3.175 cm) in diameter. NOTE: The range of any transmitter with any DCI receiver is largely dependent upon the amount of interference at a job site. The range decreases as interference increases. Transmitter Serial Number Regional Designation Number (Must Match that of Receiver) Battery Cap End Front End Cap with Temp Dot and Index Slot

Transmitter 36 DigiTrak® F2™ Operator’s Manual Batteries and Power On/Off The long-range FX transmitter requires two C-cell alkaline batteries or one DCI SuperCell Lithium Battery. The extended-range FXL requires one DCI SuperCell battery. Do not use alkaline batteries in the FXL transmitter; they would last only a few hours. Never use damaged or non-DCI lithium batteries. DCI SuperCell batteries are manufactured to military specifications. The use of damaged or lower-quality lithium batteries may damage the transmitter and/or housing and will void the DCI warranty. Installing Batteries / Power On The transmitter is powered on once the batteries are installed properly. To install batteries into the transmitter, first remove the battery cap by rotating it counterclockwise. Then insert the batteries positive terminal first into the battery compartment, as shown below. Replace the battery cap, ensuring that it bottoms out for a proper seal. C-Cell C-CellSuperCell™ Install Transmitter Batteries Positive Terminal First Use a compatible receiver to verify the signal from the transmitter. Roll, pitch, and a stable signal strength reading should be observed on the receiver. Transmitter Battery Status When alkaline batteries are used in the FX transmitter, the battery status symbol on the receiver’s depth mode screen will indicate the remaining transmitter battery life with progress bars that decrease as battery power is used. When using a DCI SuperCell battery in the FX or FXL transmitter, the battery status symbol will appear full until just before the battery dies. NOTE: Because the SuperCell battery will appear full until just before it dies, you must track the hours of use for the SuperCell battery. Sleep Mode (Automatic Shutdown) / Power Off The FX and FXL transmitters will go into sleep mode and stop transmitting to conserve battery power if they are stationary for longer than 15 minutes. To “wake” the transmitter, rotate the drill string.

Transmitter DigiTrak® F2™ Operator’s Manual 37 A small amount of charge will continue to drain from the batteries while the transmitter is in sleep mode. To conserve battery life, do not leave batteries in the transmitter when they can easily be removed, and always remove batteries when the transmitter is not being used. Transmitter Housing Requirements For maximum transmitter range and battery life, the slots in the drill housing must meet minimum length and width requirements and be correctly positioned. DCI recommends at least three slots, each at least 1/16-inch or 0.0625 in. (1.6 mm) wide and equally spaced around the circumference of the housing. For accuracy, slot measurements must be taken from the inside of the housing. For the long-range FX transmitter (15 in./38.10 cm long), the slots must be at least 8.5 in. (21.6 cm) long and begin at least 2 in. (5.1 cm) but not more than 3 in. (7.6 cm) from the front of the transmitter, as shown below. FX Transmitter Housing Slot Requirements For the extended-range FXL transmitter (19 in./48.26 cm long), the slots must be at least 13 in. (33 cm) long and begin at least 2 in. (5.1 cm) but not more than 3 in. (7.6 cm) from the front of the transmitter, as shown below. FXL Transmitter Housing Slot Requirements Both the FX and FXL transmitters are 1.25 in. (3.175 cm) in diameter and must fit snugly into the housing. It may be necessary to wrap the transmitter with tape or O-rings to prevent it from rattling in the housing. The index slot in the front end cap of the transmitter should fit onto the anti-roll pin (key) in the housing for proper alignment of the transmitter in the housing. Battery Compartment End Front End Cap Slot Position Slot Length 8.5 in. (21.6 cm) 2 in. (5.1 cm) Battery Compartment End Slot Position Slot Length 13 in. (33 cm) 2 in. (5.1 cm) Front End Cap

Transmitter 38 DigiTrak® F2™ Operator’s Manual Temperature Updates and Overheat Indicator F2 transmitters are equipped with an internal digital thermometer. The internal temperature of the trans-mitter is sent to the receiver and remote display every 2 seconds. This temperature is displayed on the bottom right of the receiver and remote display screens next to the transmitter temperature symbol . NOTE: Because the digital thermometer is inside the transmitter, temperature increases due to external drilling conditions will take time to transfer to the transmitter. Any increase in temperature should be dealt with quickly to avoid irreversible damage. Normal drilling temperatures range from 64°F (16°C) to 104°F (40°C). You should suspend drilling when temperatures exceed 95°F (35°C) to permit cooling. Once the temperature reaches 104°F (40°C) the thermometer icon will change to display steam and it will flash: . At this point, the transmitter has become dangerously hot and must be cooled immediately or it will be damaged. To stop temperature increases and cool the transmitter, slow or stop drilling and/or add more drilling fluid. Transmitter Temperature Warning Tones The audible tones emitted by the F2 receiver and remote display to indicate an increase in the transmitter temperature are summarized in the table below. Temperature Warning Tones Below 61°F (16°C) No tones for temperature increases. 61–90°F (16–32°C) Double-beep sequence (beep-beep) for every 4°C increase in temperature. 97–111°F (36–44°C) Two double-beep sequences (beep-beep, beep-beep) for every 4°C increase in temperature. NOTE: Action is required to cool the transmitter. 118–133°F (48–56°C) Three double-beep sequences (beep-beep, beep-beep, beep-beep) for every 4°C increase in temperature. NOTE: Cooling is critical to avoid ir-reversible damage. Above 140°F (60°C) Three double-beep sequences every 5 seconds on the remote display, and every 20 seconds on the receiver. NOTE: Warning signifies dangerous drilling conditions; irreversible damage may have already been done. Above 183°F (84°C) Transmitter shuts down. 220°F (104°C) Transmitter overheat indicator (temp dot) turns black (see below).

Transmitter DigiTrak® F2™ Operator’s Manual 39 Transmitter Overheat Indicator (Temp Dot) The transmitter has a temperature overheat indicator (temp dot) on the front end cap. The temp dot has an outer yellow ring with a 1/8-inch (3-mm) white dot in the center. The white dot will change color if the transmitter is exposed to excessive heat. If the temp dot changes to silver or gray, then the transmitter has been exposed to heat but not in excess of the specifications. If the temp dot is black, then the transmitter has been exposed to temperatures in excess of 220°F (104°C) and can no longer be used. The DCI warranty will be void for any transmitter that has been overheated (black dot) or had its temp dot removed. Front End Cap of Transmitter Showing Temp Dot, Index Slot, and Black Temp Dot Avoid transmitter overheating by practicing proper drilling techniques. Abrasive soils, clogged jets, in-adequate mud flow, and poorly mixed mud are some of the factors that can contribute significantly to the overheating of a transmitter. Temp Dot Index Slot at 6 o’clock Position Black Temp Dot Voids Warranty

The battery packs are used to power the F2 receiver and the FSD remote. Only DCI battery packs should be used in the F2 system and in the battery charger. Using another type of battery could result in system damage and voiding of the warranty. OK?? The battery charger can operate from AC (100–240 V, 50–60 Hz, 1.5 A max.) or DC (9–32 V, 5 A max.) power sources, and power cords are provided for both power sources. The AC power cord that is shipped with your system is standard to your global area of operation. A fully charged DCI lithium-ion battery pack will power an F2 receiver for approximately 12 hours or an FSD remote for approxi-mately 14 hours before recharging is necessary. The battery pack can be recharged approximately 400 times before the battery life is reduced by up to 50%. To check the charge status of the DCI lithium-ion battery pack at any time, press the battery status button below the five LEDs on the battery. Each of the LEDs represents 20% of the battery charge. While charging, the LEDs will flash to show the current charge level. Upon completion of the charge cycle, all five LEDs will illuminate briefly and then turn off.

DIGITAL CONTROL INCORPORATED DigiTrak® F2™ Operator’s Manual 55 Locating Locating in High-Interference Area with the F2 Receiver Introduction Locating with the F2 system is relatively easy and intuitive, but you must understand some locating basics first. This section describes the locate points and locate line; the geometry of these elements with respect to the transmitter; the display screens encountered during locating; and the proper method for marking locate points once they are found. You are then given the standard locating procedure, including tracking “on-the-fly,” and a method for tracking the transmitter when you cannot walk over it, called off-track locating. For a detailed explanation of how to track the transmitter when it is steep and deep, please read the information provided in Appendix B: Projected Depth Versus Actual Depth and the Fore/Aft Offset.

Locating 56 DigiTrak® F2™ Operator’s Manual Locate Points (FLP & RLP) and Locate Line (LL) The F2 receiver locates the transmitter by detecting three specific places in the transmitter’s magnetic field: the locate points and the locate line. The locate points are indistinguishable from one another by the receiver. They represent similar points in the transmitter’s field in front of and behind the transmitter. The front locate point (FLP) is ahead of the transmitter, and the rear locate point (RLP) is behind the transmitter. (See Appendix B for more information about the transmitter’s magnetic field.) The locate line (LL) extends 90° to the left and right of the transmitter and represents the location of the transmitter between the FLP and RLP. The most accurate tracking requires the use of all three locations to determine the position, heading, and depth of the transmitter. Aligning the FLP and RLP reveals the heading and left/right position of the transmitter. The LL determines the central position and depth of the transmitter when the receiver is properly aligned between the FLP and RLP. The full procedure for tracking is given later in this section under “Standard Method for Locating the Transmitter.” TransmitterSurface of Geometry of FLP, RLP, and LL from Top (Bird’s Eye) and Side Views Note how the RLP and FLP are equal distances from the LL when the transmitter is level. NOTE: If the transmitter pitch exceeds ±30% (or ±17°) and/or the transmitter depth exceeds 15 ft (4.5 m), the position of the locate line will be somewhat ahead of or behind the transmitter’s actual position. In these cases, the depth displayed on the receiver is referred to as the projected depth (see Appendix B for more information regarding this situation).

Locating DigiTrak® F2™ Operator’s Manual 57 Effects of Depth, Pitch, and Topography on Distance Between FLP and RLP In general, the deeper the transmitter is, the further apart the FLP and RLP will be. The distance between the FLP and RLP with respect to the location of the LL is also a function of the transmitter pitch and topography. (For more information, see Appendix B.) When the transmitter pitch is negative, the FLP will be further from the LL than the RLP (see figure below). When the transmitter pitch is positive, the RLP will be further from the LL than the FLP. If the ground surface or topography slopes significantly, the locations of the FLP and RLP will also be affected with respect to the LL even if the transmitter itself is level. Surface ofTransmitter (Negativeor Downward Pitch)Transmitter (Negativeor Downward Pitch) Effect of Pitch on Distance Between FLP, RLP, and LL Note how the RLP and FLP are at different distances from the LL when the transmitter is at a negative pitch (compare with figure on previous page in which the transmitter is level). It is possible to calculate depth (for comparison to the receiver’s depth reading) using the distance between the locate points and the pitch of the transmitter. For additional information, see Appendix C: Calculating Depth Based on Distance Between FLP and RLP. It is also possible to track the locate line when walkover locating is not possible, such as when surface obstructions exist or interference occurs. For more information about this feature, called off-track locating, see “Off-Track Locating” at the end of this section.

Locating 58 DigiTrak® F2™ Operator’s Manual Marking Locate Points The locate points (FLP and RLP) and the locate line (LL) must be found and accurately marked during the locating procedure. To mark a locate point after you have found it, stand with the receiver level and directly above the locate point. Look down the vertical axis that runs through the center of the display to project a plumb line to the ground (see figure below). The point where this plumb line hits the ground is the location that you should mark. Center ofDisplayFront ofReceiverPlace MarkerStraight Downon GroundPlumb Line orVertical Axis Plumb Line for Marking Locate Points HANDLING THE RECEIVER NOTE: It is critical that you hold the receiver correctly to obtain accurate readings. You must hold the receiver level at all times and maintain a constant height-above-ground (HAG) distance that matches the value set on the receiver (see “Height-Above-Ground (HAG) Menu” in the Receiver section).

Locating DigiTrak® F2™ Operator’s Manual 59 Display Screens The locate mode screen on the F2 receiver provides real-time data about the transmitter’s temperature, pitch, roll, and signal strength. Receiver Locate Mode Screen When the F2 receiver is positioned at the locate line between the FLP and the RLP and the trigger is held in, you will see the depth mode screen. This screen provides more detailed data about the position of the transmitter with respect to the receiver. It also shows the battery status of the transmitter. NOTE: The receiver and transmitter must be calibrated together, with the transmitter in the drill housing, before accurate depth data can be displayed. See “Calibration Menu” in the Receiver section.

Locating 60 DigiTrak® F2™ Operator’s Manual If the HAG is turned off, the receiver will have to be set on the ground for accurate depth readings. In this case, the picture on the depth mode display will show the receiver on the ground. When the F2 receiver is positioned at one of the locate points and the trigger is held in, you will see the predicted depth screen. The value for predicted depth and horizontal distance are only valid if the receiver is at the FLP. The “R” at the top of the screen denotes that the reference signal is being taken. See “Standard Method for Locating the Transmitter” later in this section for more information on the reference lock and positioning the receiver at the locate points. Receiver Predicted Depth Screen (at FLP with HAG on) The depth screen can be accessed at any time during locating. However, depth and predicted depth data will only be displayed when the receiver is at the locate line and locate points, respectively. The depth screen will display as follows when the receiver is not positioned at a locate point or the locate line.

Locating DigiTrak® F2™ Operator’s Manual 61 Interference: What It Is and How to Check for It Before drilling (preferably before bidding on a project) the interference potential at your site should be evaluated. Interference can reduce the transmitter’s range or cause variable readings and possibly result in job slowdowns. Interference comes from two different types of sources: active and passive. Active interference is also known as electrical interference or background noise and can have varying effects upon the F2 locating equipment. Most electrical devices emit signals that can affect your ability to locate the tool accurately or to get good pitch/roll readings. Some examples of active interference are traffic signal loops, buried dog fences, cathodic protection, radio communications, microwave towers, cable TV, fiber-trace lines, utility data transmissions, security systems, power lines, and phone lines, to name a few. Passive interference can reduce the amount of signal received from the transmitter, which results in deeper than expected depth readings or a completely blocked signal. Some examples of passive interference are metal objects (such as pipes, rebar, trench plate, chain-link fence, or vehicles). Two other examples of passive interference are saltwater/salt domes and conductive earth, such as iron ore. To install your product accurately and safely, the location of every underground structure proximal to the intended bore path should be confirmed by potholing. This task is the first step in familiarizing yourself with the interference potential along your intended bore path. The next step is to conduct an electrical interference/background noise check. There are two steps to the interference/background noise check. The first step requires one person, the second step requires two people. CAPTION With the transmitter off, power up the receiver and walk the bore path while monitoring the signal strength on the receiver’s screen, noting any locations where it changes. A general rule is that the background noise should be at least 150 points less than the transmitter’s signal strength when measured at the maximum depth for that bore.

Locating 62 DigiTrak® F2™ Operator’s Manual CAPTION At the end of the bore path, have your coworker install batteries in the transmitter to power it up. With the receiver positioned on the intended bore path, have your coworker with the transmitter, step off to your side approximately 1.5 times the maximum depth of your intended bore. You will now walk back toward the launch end in tandem, maintaining this distance of 1.5X the max depth while periodically stopping to change the transmitter’s pitch and roll orientation to verify the speed and accuracy of these readings on the receiver. Suggestions for Dealing with Interference Every job site warrants an interference/background noise check no matter how remote and interference-free your job site appears to be. If the pitch/roll information becomes erratic or is lost, move the receiver away from the interference source while staying within range of the transmitter. Separation (use of the HAG function) may also help when under metallic objects, because the greater the separation between the receiver and the metal objects, the better the receiver’s antenna will read the signal. Another solution is to use a transmitter with a stronger signal strength that may be able to overcome the interference/ background noise. 1. Walk the intended bore path with the receiver on and in locate mode, watching for any background noise that affects the signal strength and could interfere with the transmitter’s signal. The transmitter must be off during this test. Tolerable levels for background noise vary depending on the depth of the bore and ground conditions. A general rule is that the background noise should be at least 150 points less than the signal strength at the bore’s maximum depth. Make note of any problem areas, and take steps to reduce the interference if possible. See the Safety Precautions and Warnings section for more information on interference. NOTE: The high-powered FXL transmitter can be a useful option if the minimum signal strength requirement cannot be met with the FX transmitter. Other options include getting the transmitter at depth and level before entering a problem area so that off-track locating or Target Steering methods can be applied. 2. With the transmitter turned on and in its housing, place the transmitter on the ground. Then place the receiver to the side of the housing as far as the maximum intended bore depth.

Locating DigiTrak® F2™ Operator’s Manual 63 Maximum Bore Depth CAPTION Make note of the signal strength and verify that roll and pitch are displayed and that the depth reading on the receiver is accurate. Verify depth readings at several locations along the intended bore path with a tape measure. If necessary, recalibrate in an area where the background noise is lower than 100 points. 3. Follow all other pre-drill procedures required by the job and industry standards for a safe and effective HDD process.

Locating 64 DigiTrak® F2™ Operator’s Manual Standard Method for Locating the Transmitter With the F2 system, you can locate the transmitter and its heading while it moves, whether standing in front of it, behind it, or toward the side. You can also locate the transmitter facing either toward or away from the drill rig. The standard method described in this section guides you to the transmitter while standing out in front of it, facing the drill rig. This is the recommended method for locating. As you continue to drill or as the bore path curves, you may be facing the last marked locate point rather than the drill rig. DrillLLFLPRLPMoveForward DrillLLFLPRLPMoveForward Setup for Standard Locating Method Standard Locating Method with a Curved Path Depth readings may be taken at the FLP or at the LL. It is necessary to hold the trigger in to view the depth or predicated depth and to send the depth reading to the remote display. Finding the Front Locate Point (FLP) The locating procedure described here assumes you are facing the drill with the transmitter below ground and between you and the drill. 1. Start with the receiver on and in locate mode. 2. Stand out in front of the drill head at a distance of approximately one rod length. NOTE: The FLP will be found further out in front of the drill head as the drill head gets deeper.

Note that the FLP is ahead of and to the left of the receiver, as shown in the receiver display. RLPFLPLL Receiver Locate Mode Screen Actual Position of Receiver and Transmitter 4. Walk in the direction indicated by the picture on the screen to center the target in the box, which is forward and to the left in this example. 5. When the target is centered in the box, hold the trigger in for one second so the receiver can get a “lock” on the reference signal. The “R” symbol will appear at the top of the depth screen.

Locating 68 DigiTrak® F2™ Operator’s Manual 10. Mark the location directly below the receiver’s display screen on the ground as the LL. You can take a depth reading here by holding in the trigger. However, to be certain you are directly above the trans-mitter, and your depth reading is accurate, you should first find the RLP. NOTE: If the locate line does not appear, hold the trigger and move the receiver in a forward/aft direction over where you think the tool is located. This should re-reference the receiver to the transmitter's signal, and bring up the locate line. Finding the RLP to Confirm Transmitter Heading and Position Finding the RLP will allow you to confirm the transmitter’s heading and position. Like the FLP, the RLP is represented as a target ( ) on the receiver display. Once the RLP is found, you will connect the RLP to the FLP with a line that represents the exact heading of the transmitter. The transmitter is located at the point where this line intersects the LL. Continue the locating procedure as follows: 11. From the LL, facing toward the drill or last transmitter location, walk forward keeping the target aligned on the vertical crosshairs.

Position the receiver at the intersection of these lines with the LL passing through the center of the box on the display and hold the trigger in to take a depth reading. NOTE: To verify the depth reading, turn off the HAG and set the unit on the ground. Take another depth reading. This reading should be very near the depth reading obtained with the HAG on and the receiver lifted.

Once the FLP is in the box, hold the trigger in and confirm that the predicted depth reading is as expected. Off-Track Locating The off-track locating technique is useful when it is not possible to walk above the transmitter due to a surface obstruction or interference. Using the locate line’s perpendicular relationship to the transmitter, it is possible to track the transmitter’s heading and also to determine if it is maintaining its intended depth. The off-track locating method is only effective when the pitch of the transmitter matches the pitch of the topography. Ideally, pitch will be 0% (0°) on flat ground. To explain how the off-track locating method works, we will use the example of an obstruction that is over the intended bore path, as shown in the figure below. The transmitter is about to go under the obstruction. 1. Stop drilling and find the LL of the transmitter by putting the line in the box. 2. While holding the trigger in and keeping the receiver in the same orientation, step to the side of the tool until you reach a predetermined distance (P1) from it. Move the receiver forward and aft until you can see the ball jump from the bottom of the screen to the top of the screen (or vice versa), then mark this location. Must fix these drawings

After finding the three locations P1, P2, and P3 to the side of the transmitter, connect these locations with a line. This is the locate line. Because the LL runs perpendicular (at a 90° angle) to the transmitter, it is possible to determine the heading of the tool. By comparing the slant distance or signal strength at the predetermined distances of P1, P2, and P3, as the tool progresses you can verify if the drill head is moving away from or closer to the intended bore path. This allows steering corrections to be made.

Locating DigiTrak® F2™ Operator’s Manual 73 6. As drilling continues, the tool should be steered to maintain a constant slant distance at each of the points P1, P2, and P3.

DIGITAL CONTROL INCORPORATED DigiTrak® F2™ Operator’s Manual 75 The Target Steering Function The Target Steering function allows the F2 receiver to be placed out ahead of the drill head and used as a steering target. The receiver is positioned on level ground so that it is facing in the same direction as the drilling. To activate the Target Steering function, you must program the receiver with the desired target depth number. The drill head can then be guided to a point directly below where the receiver has been placed using the Target Steering screen on the remote display. The F2 system assumes level topography for the most accurate Target Steering results. It also assumes a conservative bend radius. Therefore, in situations with significant pitch changes, such as during the launch/exit ends, the up/down steering information on the remote display may not be accurate. In these situations, only the left/right steering information should be considered accurate. As a general rule, the depth cannot change by more than 4 ft (1.2 m) per 35 ft (10.7 m), and the pitch cannot change by more than 14% per 35 ft (10.7 m). Feasible Target Depth and Positioning the Receiver as a Target The Target Steering procedure requires correct placement of the receiver. The receiver must be placed out in front of the transmitter with its back end (where the battery pack is inserted) facing the drill. The maximum horizontal distance from the transmitter that the receiver should be placed is approximately 35 ft (10.7 m). The receiver must be programmed with the desired target depth number. To program the receiver, see the instructions under "Target Steering Menu" in the Receiver section. The figure below shows the receiver’s locate screen with the Target Steering distance at the bottom. This number is the horizontal distance that the receiver is from the transmitter. You will use this number to help you position the receiver a maximum distance of 35 ft (10.7 m) ahead of the tool. Receiver Screen with Target Depth Programmed Horizontal Distance Between Transmitter and Receiver

Target Steering 76 DigiTrak® F2™ Operator’s Manual The maximum distance that the receiver can be placed out ahead of the drill head for Target Steering is 35 ft (10.7 m). Over this 35-ft range, the following parameters apply:  The maximum depth change is approximately 4 ft (1.2 m).  The maximum pitch change is approximately 14%. To determine if your desired target depth is feasible: 1. Use the receiver to obtain the current transmitter depth with respect to level ground surface. 2. Subtract the current transmitter depth from your desired target depth to obtain the desired depth change. Steering to the Target Once the target depth number has been entered on the receiver and the receiver has been positioned ahead of the tool as the target, then select remote mode from the remote's main menu (see "Main Menu" in the Remote Display section). You will then see the Target Steering screen shown below. Target Steering on Remote Display The steering indicator in this case shows that the drill head is to the left and too high for the intended path. The steering indicator should be dead center in the display if you are correctly heading to your programmed target depth. A steering command of 4 o’clock would bring the drill head toward the target. Note that, for quick viewing and interpretation, the pointed end of the steering indicator corresponds to the clock position of the head. The horizontal distance from the drill head to the receiver is indicated at the bottom left part of the display. At the bottom right, the current depth of the drill head is indicated.

Appendix A 80 DigiTrak® F2™ Operator’s Manual General Transmitter Care Instructions  Periodically clean the spring and threads inside the battery compartment as well as the spring and threads of the battery cap to ensure a proper power connection with the batteries. An emery cloth or wire brush can be used to remove any oxidation that has built up. Be careful not to damage the battery cap O-ring; remove it while cleaning if necessary. After cleaning, use a conductive lubricant on the battery cap threads to keep the battery cap from binding in the battery compartment.  Before use, inspect the battery cap O-ring for damage that may allow water to enter the battery compartment. Replace the 2-022 Buna-N70 type O-ring if the one installed becomes damaged.  Placing tape around the fiberglass tube of the transmitter, if space allows, will keep the fiberglass protected from most corrosive environmental wear.  Send in the Product Registration Card for the 90-day limited warranty.

DIGITAL CONTROL INCORPORATED DigiTrak® F2™ Operator’s Manual 81 Appendix B: Projected Depth Versus Actual Depth and the Fore/Aft Offset What Happens When the Transmitter Is Steep and Deep The signal field emitted by the transmitter, as shown in Figure B1, consists of a set of elliptical signals or flux lines. The flux lines indicate the position of the transmitter. When the transmitter is level with respect to the ground, you will find that the locate line (LL) is directly over the transmitter, and the depth displayed on the receiver is the actual depth. You will also find that the locate points (FLP and RLP) are at equal distances from the transmitter. The location of the LL is found at the intersection of the ground and the horizontal component of the flux field, and the FLP and RLP are found where the vertical components of the flux field intersect with the ground. Some of the horizontal and vertical components are identified by short yellow lines in Figure B1. RLP FLPLL Figure B1. Flux Field and Geometry of FLP, RLP, and LL (side view)

Appendix B 82 DigiTrak® F2™ Operator’s Manual Due to the shape of the transmitter’s signal field (flux lines), when it is at a pitch greater than ±30% (±17°) and/or a depth of 15 ft (4.5 m) or more, the position of the locate line will be some distance ahead of or behind the transmitter’s actual position. In this case, the depth displayed on the receiver becomes what is called the projected depth. The transmitter’s distance ahead of or behind the locate line is called the fore/aft offset. The projected depth and fore/aft offset, shown in Figure B2, must be accounted for when the transmitter is steep and/or deep. See the tables provided later in this appendix (Tables B1 and B2) to determine the actual depth and fore/aft offset when you know the displayed (projected) depth and pitch of the transmitter. LLLPLP Fore/Aft OffsetProjected Depth Actual Depth30% (17°)Pitch Figure B2. Projected Depth vs. Actual Depth and Fore/Aft Offset When Steep and Deep Figure B2 above shows a transmitter positioned in a drill string that is meant to illustrate drilling at either a positive or a negative pitch—the pitch is positive if you are drilling left to right, and it is negative if you are drilling right to left. The transmitter’s signal field is also pitched at the same angle as the transmitter. The locate line (LL), which is where the depth measurement is taken, is the horizontal component of the transmitter’s signal field flux lines. That is, the LL is found where the flux lines are horizontal, as illustrated with short horizontal yellow lines in the figure above.

Appendix B DigiTrak® F2™ Operator’s Manual 83 The locate points (FLP and RLP) are also shown in Figure B2. These points are located at the vertical components of the signal field, as illustrated with short vertical yellow lines in the figure above. Note that the locate points are not the same distance from the LL when the transmitter is pitched. Again, this situation requires compensation for the projected depth and the fore/aft offset. Using the tables provided below, you can look up the actual depth (Table B1) and the fore/aft offset (Table B2) based on the receiver’s depth reading (projected depth) and the transmitter pitch. You can also look up the projected depth (Table B3) if you know the required depth (actual depth) of your instal-lation and you want to find the corresponding projected depth reading that you will see on the receiver during drilling. The final table (Table B4) provides conversion factors for determining the projected depth from the actual depth or the actual depth from the projected depth at various transmitter pitches. Table B1 lists the projected or displayed depth values (shown in red) in 5 ft (1.52 m) increments in the first column and provides values for the actual depth (shown in green) at different transmitter pitches. For example, if you have a displayed depth of 25 ft (7.62 m) and your transmitter is at a 40% (22°) pitch, then you can see from Table B1 that the actual depth of the transmitter is 22 ft 8 in. (6.91 m). Table B1.

Appendix B DigiTrak® F2™ Operator’s Manual 85 Table B4 allows you to calculate the exact projected depth reading as well as the actual depth using a multiplier. Values for the multiplier, or conversion factor, are provided at different transmitter pitches. Table B4. Conversion Factors for Calculating Exact Projected Depth or Actual Depth Pitch → ±10% (5.7°) ±20% (11°) ±30% (17°) ±40% (22°) ±50% (27°) ±60% (31°) ±75% (37°) ±90% (42°) From Actual to Projected Depth 1.005 1.025 1.06 1.105 1.155 1.212 1.314 1.426 From Projected to Actual Depth 0.995 0.975 0.943 0.905 0.866 0.825 0.761 0.701 For example, referring to Table B4, if you have a required (actual) depth of 24 ft (7.32 m), you can determine the receiver’s projected depth reading at a 30% (17°) pitch. You will use the first row of conversion factors (From Actual to Projected Depth) to select the corresponding value for a pitch of 30%, which is 1.06. Multiply this value by the required depth, which is 24, and you will find that your receiver’s projected depth reading at the locate line should display as 25 ft 5 in. (7.75 m) Using the projected depth displayed on your receiver, you can calculate the actual depth of the transmitter using the second row of conversion factors. Select the corresponding conversion factor associated with your pitch value, then multiply that value by the projected depth. For example, if your pitch is 30% and your projected depth reading is 24 ft (7.32 m), then you would multiply 0.943 by 24 to determine that the actual depth of the transmitter is 22.63 ft or 22 ft 8 in. (6.90 m).

DIGITAL CONTROL INCORPORATED DigiTrak® F2™ Operator’s Manual 87 Appendix C: Calculating Depth Based on Distance Between FLP and RLP It is possible to estimate the transmitter depth should the information displayed on the receiver become unreliable. This is only possible if you know the transmitter pitch and the positions of the front locate point (FLP) and the rear locate point (RLP) and if the ground surface is level. To estimate the transmitter depth, first measure the distance between the FLP and the RLP. The pitch of the transmitter must also be reliably known. Using the Depth Estimation Table below, find the divider that most closely corresponds to the transmitter pitch. Then use the following formula to estimate the depth: DividerRLPandFLPbetweenDistanceDepth = For example, if the transmitter pitch is 34% (or 18.8°) then the corresponding divider value (from the table) is 1.50. In this example, the distance between the FLP and the RLP is 11.5 ft (3.5 m). The depth would be: 7.661.50ft 11.5Depth ==ft or approximately 7.7 ft (2.35 m) Table C1.

DCI's sole obligation under this Limited Warranty shall be limited to either repairing, replacing, or adjusting, at DCI's option, a covered DCI Product that has been determined by DCI, after reasonable inspection, to be defective during the foregoing Warranty Period. All warranty inspections, repairs and adjustments must be performed either by DCI or by a warranty claim service authorized in writing by DCI. All warranty claims must include proof of purchase, including proof of purchase date, identifying the DCI Product by serial number. 3. The Limited Warranty shall only be effective if: (i) within fourteen (14) days of receipt of the DCI Product, User mails a fully-completed Warranty Registration Card to DCI; (ii) User makes a reasonable inspection upon first receipt of the DCI Product and immediately notifies DCI of any apparent defect; and (iii) User complies with all of the Warranty Claim Procedures described below. WHAT IS NOT COVERED This Limited Warranty excludes all damage, including damage to any DCI Product, due to: failure to follow DCI’s user’s manual and other DCI instructions; abuse; misuse; neglect; accident; fire; flood; Acts of God; improper applications; connection to incorrect line voltages and improper power sources; use of incorrect fuses; overheating; contact with high voltages or injurious substances; use of batteries or other products or components not manufactured or supplied by DCI; or other events beyond the control of DCI. This Limited Warranty does not apply to any equipment not manufactured or supplied by DCI nor, if applicable, to any damage or loss resulting from use of any DCI Product outside the designated country of use. By accepting a DCI Product and not returning it for a refund within thirty (30) days of purchase, User agrees to the terms of this Limited Warranty, including without limitation the Limitation of Remedies and Liability described below, and agrees to carefully evaluate the suitability of the DCI Product for User's intended use and to thoroughly read and strictly follow all instructions supplied by DCI (including any updated DCI Product information which may be obtained at the above DCI website). In no event shall this Limited Warranty cover any damage arising during shipment of the DCI Product to or from DCI. User agrees that the following will render the above Limited Warranty void: (i) alteration, removal or tampering with any serial number, identification, instructional, or sealing labels on the DCI Product, or (ii) any unauthorized disassembly, repair or modification of the DCI Product. In no event shall DCI be responsible for the cost of or any damage resulting from any changes, modifications, or repairs to the DCI Product not expressly authorized in writing by DCI, and DCI shall not be responsible for the loss of or damage to the DCI Product or any other equipment while in the possession of any service agency not authorized by DCI.

3-2200-00-A Page 2 of 2 DCI reserves the right to make changes in design and improvements upon DCI Products from time to time, and User understands that DCI shall have no obligation to upgrade any previously manufactured DCI Product to include any such changes. THE FOREGOING LIMITED WARRANTY IS DCI’S SOLE WARRANTY AND IS MADE IN PLACE OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE AND ANY IMPLIED WARRANTY ARISING FROM COURSE OF PERFORMANCE, COURSE OF DEALING, OR USAGE OF TRADE, ALL OF WHICH ARE HEREBY DISCLAIMED AND EXCLUDED. If DCI has substantially complied with the warranty claim procedures described below, such procedures shall constitute User’s sole and exclusive remedy for breach of the Limited Warranty. LIMITATION OF REMEDIES AND LIABILITY In no event shall DCI or anyone else involved in the creation, production, or delivery of the DCI Product be liable for any damages arising out the use or inability to use the DCI Product, including but not limited to indirect, special, incidental, or consequential damages, or for any cover, loss of information, profit, revenue or use, based upon any claim by User for breach of warranty, breach of contract, negligence, strict liability, or any other legal theory, even if DCI has been advised of the possibility of such damages. In no event shall DCI’s liability exceed the amount User has paid for the DCI Product. To the extent that any applicable law does not allow the exclusion or limitation of incidental, consequential or similar damages, the foregoing limitations regarding such damages shall not apply. This Limited Warranty gives you specific legal rights, and you may also have other rights which vary from state to state. This Limited Warranty shall be governed by the laws of the State of Washington. WARRANTY CLAIM PROCEDURES 1. If you are having problems with your DCI Product, you must first contact the Authorized DCI Dealer where it was purchased. If you are unable to resolve the problem through your Authorized DCI Dealer, contact DCI’s Customer Service Department in Kent, Washington, USA at the above telephone number between 6:00 a.m. and 6:00 p.m. Pacific Time and ask to speak with a customer service representative. (The above “800” number is available for use only in the USA and Canada.) Prior to returning any DCI Product to DCI for service, you must obtain a Return Merchandise Authorization (RMA) number. Failure to obtain a RMA may result in delays or return to you of the DCI Product without repair. 2. After contacting a DCI customer service representative by telephone, the representative will attempt to assist you in troubleshooting while you are using the DCI Product during actual field operations. Please have all related equipment available together with a list of all DCI Product serial numbers. It is important that field troubleshooting be conducted because many problems do not result from a defective DCI Product, but instead are due to either operational errors or adverse conditions occurring in the User’s drilling environment. 3. If a DCI Product problem is confirmed as a result of field troubleshooting discussions with a DCI customer service representative, the representative will issue a RMA number authorizing the return of the DCI Product and will provide shipping directions. You will be responsible for all shipping costs, including any insurance. If, after receiving the DCI Product and performing diagnostic testing, DCI determines the problem is covered by the Limited Warranty, required repairs and/or adjustments will be made, and a properly functioning DCI Product will be promptly shipped to you. If the problem is not covered by the Limited Warranty, you will be informed of the reason and be provided an estimate of repair costs. If you authorize DCI to service or repair the DCI Product, the work will be promptly performed and the DCI Product will be shipped to you. You will be billed for any costs for testing, repairs and adjustments not covered by the Limited Warranty and for shipping costs. In most cases, repairs are accomplished within 1 to 2 weeks. 4. DCI has a limited supply of loaner equipment available. If loaner equipment is required by you and is available, DCI will attempt to ship loaner equipment to you by overnight delivery for your use while your equipment is being serviced by DCI. DCI will make reasonable efforts to minimize your downtime on warranty claims, limited by circumstances not within DCI’s control. If DCI provides you loaner equipment, your equipment must be received by DCI no later than the second business day after your receipt of loaner equipment. You must return the loaner equipment by overnight delivery for receipt by DCI no later than the second business day after your receipt of the repaired DCI Product. Any failure to meet these deadlines will result in a rental charge for use of the loaner equipment for each extra day the return of the loaner equipment to DCI is delayed.
