ST Transmitter
DigiTrak SE Locating System
The DigiTrak SE Locating System is used during horizontal directional drilling operations to locate and
track a transmitter installed in the drill head. You can use your existing DigiTrak Mark Series remote, MFD
(Multi-Function Display) remote, or FSD (F Series Display) remote to view the transmitter data at the drill
rig. The system consists of a handheld receiver, a transmitter, a battery charger system, and two
rechargeable nickel-metal hydride (NiMH) battery packs used for powering the receiver.
Locating is streamlined using the SE 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 SE system includes the
advanced features of predicted depth, off-track locating, and remote steering to navigate the drill head
easily and accurately even when obstacles prevent walkover tracking.
This manual provides information on each SE system component—the receiver, transmitter, 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. For instructions on using your Mark Series, MFD, or FSD remote, see the operator’s manual provided with your
remote display.

DigiTrak SE™ Operator’s Manual
Introduction
The SE 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 ST transmitter in Transmitter section). Also, the
receiver’s telemetry frequency designation must match that of the remote display being used.
Appendix A presents the SE system’s power, environmental, and maintenance requirements. Appendix B
explains how to calculate depth when the transmitter is deep (greater than 15 ft or 4.6 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. Finally,
Appendix D provides reference tables for depth and pitch conversions.

General Description
The SE receiver is a handheld unit used for locating and tracking an SE transmitter. The receiver
converts signals from the transmitter and displays the following transmitter information: depth, pitch, roll,
temperature, and battery level. The SE receiver then sends this 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. It must match one of
those listed on the remote display’s serial number label located on the back of the unit.
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). This number must match that stamped on the transmitter for proper
communication (see photo of ST transmitter in Transmitter section).

1-Point Calibration (Above Ground)
The 1PT CAL procedure is performed with the transmitter turned on and in the drill head, parallel to and
10 ft (or 3 m) from the receiver as described below. DCI does not recommend calibrating every day, but
you should verify the receiver’s depth reading daily at several locations using a tape measure.
NOTE: Calibration is necessary prior to first-time use and before a different transmitter, receiver, or
drill head is to be used.
The 1-point calibration menu display appears as follows:

To calibrate:
1. The receiver must be parallel to and level with the transmitter. It is preferable to conduct the
procedure on level ground.
2. Measure 10 ft (3 m) from the center of the transmitter to the inside edge of the receiver as shown
above in the 1PT CAL screen.
3. Verify that roll and pitch values are being displayed on the receiver and that a steady signal is
being received from the transmitter.

2 Point Calibration (In Ground)
The 2PT CAL option allows you to calibrate the receiver to the transmitter when it is in the ground. This
procedure requires the use of a tape measure. Two-point calibration is rarely needed. If you must
calibrate with the transmitter in the ground, use this procedure with caution.
Position the receiver on the ground above an approximately level transmitter. (See the Locating section
for instructions on how to position the receiver directly over the transmitter.) Start the 2-point calibration
procedure by selecting 2PT CAL from the calibration menu. You will see the following screen.
First Point, 2PT CAL
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.

SE Transmitter Specifications
DCI manufactures the standard-range ST transmitter for use with the SE system. It transmits a signal at
12 kHz and provides depth readings to approximately 50 ft (15.24 m). Pitch readings are displayed in 1%
or 1° increments (from 0% to 100% or 0° to 45°).
The transmitter fits inside the drill housing and emits electromagnetic signals that the SE 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
) near the serial number on the transmitter’s battery compartment, as shown in the
the globe icon (
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.)

The ST transmitter measures 15 in. (38.1 cm) long and 1.25 in. (3.175 cm) in diameter and must fit snugly
in the transmitter housing. See “Transmitter Housing Requirements” later in this section.
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.

Batteries and Power On/Off
The standard-range ST transmitter requires two C-cell alkaline batteries or one DCI SuperCell Lithium
Battery. 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-Cell
SuperCell™
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 using alkaline batteries, the battery status symbol at the bottom of the receiver’s depth mode
screen will indicate the battery life remaining. When using a DCI SuperCell battery in the ST 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 ST transmitter 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.
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 standard-range ST transmitter (15 in./38.1 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.

ST Transmitter Housing Slot Requirements
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. When the drill head's 12 o'clock position does not
match that of the transmitter, use the receiver’s roll offset function to display appropriate roll values. See
the “Roll Offset Menu” in the Receiver section.
Temperature Updates and Overheat Indicator
The ST transmitter is equipped with an internal digital thermometer. The internal temperature of the transmitter is sent to the receiver and remote display every 2 seconds. This temperature is displayed on the
bottom right of the receiver display screen next to the transmitter temperature symbol
. See the opera-
tor’s manual provided with your remote display to see how your remote graphically indicates transmitter
temperature.
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 118°F (48°C) the
thermometer icon will change to display steam and it will flash:
. At this point, the transmitter has be-
come 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.

The DCI SE Battery Charger (SBC) system includes an AC power cord, a power unit attached to the
battery charger, and two rechargeable NiMH battery packs. The battery packs are used to power the SE
receiver. Only DCI battery packs should be used in the SE receiver. Using another type of battery could
result in damage and voiding of the warranty. Although the SE receiver can accept a DCI lithium-ion
battery, you cannot charge a lithium-ion battery pack in the SBC charger.
The battery charger operates from an AC (100–240 V, 50–60 Hz, 0.35 A max.) power source. The AC
power cord that is shipped with your system is standard to your global area of operation.
A fully charged DCI NiMH battery pack will power an SE receiver for approximately 6 hours before
recharging is necessary. A battery will take approximately 3 hours to recharge. If power to the charger is
interrupted while charging a battery, the charger will reset and start a new charge cycle when power is
again supplied.
NOTE: The DCI NiMH battery pack must be fully charged and fully discharged twice before optimum
battery performance can be expected.
This battery charger is only designed for indoor use and should not come into contact with water or dust.
To avoid overheating, the charger should not be covered when it is in use.

Locating in High-Interference Area with the SE Receiver
Introduction
Locating with the SE 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 offtrack 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
Locate Points (FLP & RLP) and Locate Line (LL)
The SE 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.”

NOTE: If the transmitter pitch exceeds ±30% (or ±17°) and/or the transmitter depth exceeds 15 ft
(4.6 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).

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.

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.

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.

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).

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 SE locating equipment. Most electrical devices emit signals that can affect your ability to
locate the tool accurately or to get good pitch/roll readings. Typically active interference can result in
shallower than expected depth 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. You can
conduct a test for the presence of active interference with your SE system; see "Conducting a
Background Noise Check" below.
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. You
cannot conduct a test for the presence of passive interference with your SE system. Conducting a
thorough site investigation prior to drilling is the best method of identifying passive interference sources.
The first step in familiarizing yourself with the interference potential along your intended bore path. The
second step is to verify the speed and accuracy of the roll and pitch information.
Conducting a Background Noise Check
With the transmitter off, power up the SE 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. In the figure below, the red flag area denotes an increase in
background noise.

Roll/Pitch Check
At the end of the bore path, have a coworker install batteries in the transmitter to power it up. With the
receiver positioned on the intended bore path, have the 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. In particular, note any locations where you lose the update meter bars and/or inaccurate
pitch or roll readings are observed.

Two-Person Roll/Pitch Test with Transmitter
Suggestions for Dealing with Interference
Every job site warrants an interference/background noise check no matter how remote and interferencefree 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 drilling under metallic objects. The greater the separation between the
receiver and the metal, the better the receiver’s antenna will read the signal. Another recommendation is
to use a transmitter with a stronger signal strength that may be able to overcome the interference/
background noise.

Standard Method for Locating the Transmitter
With the SE 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.

WARNING: Do not hold the trigger in unless you are precisely at the FLP (target centered in box). If
you are ahead of the FLP, you will set an incorrect reference that causes a ghost locate
line. In this case, you must reference again at the FLP.

The depth value given at the FLP is the depth the transmitter will be at when it reaches its predicted
location if no steering adjustments are made.
NOTE: To verify that the signal is balanced through the receiver’s antenna, carefully rotate the
receiver 360° about the center of the display keeping the receiver level. The locating target
should stay centered in the box. If it does not, do not continue to use the receiver and
contact DCI’s Customer Service Department.
6. Mark the location directly below the receiver’s display screen on the ground as the FLP.

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 transmitter, and your depth reading is accurate, you should first find the RLP.
NOTE: If the locate line does not appear, move the receiver in a forward/aft direction over where
you think the tool is located. You will see the locating target jump from the bottom of the
screen to the top (or vice versa). Then hold the trigger; 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:

15. 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.

Tracking “On-the-Fly”
If you are running at 0% (0°) pitch over level ground, the predicted depth will be the actual depth. In this
case, all locating can be done at the FLP while the tool is moving.
Once the transmitter has been found and its heading is on line, position yourself the distance of one rod
length in front of the FLP on the intended bore path with the receiver facing the drill and sitting level on
the ground.

As the tool advances, the FLP should travel along the receiver's vertical crosshairs indicating that the tool

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°) under flat ground.
To explain how the off-track locating method works, we will use the example of an obstruction that is on
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.

then mark this location.
5. 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.

The remote steering function allows the SE receiver to be placed out ahead of the drill head and used as
a left/right steering target. The receiver is positioned on level ground so that it is facing in the same
direction as drilling. To activate the remote steering function, you must program a reference depth into the
receiver that matches your current drilling depth. See “Menu Options” in the Receiver section. When
remote steering has been activated, the locate screen on the receiver will appear as shown below.


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.

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.

Appendix B
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 (4.6 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.

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
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 installation 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).

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, and 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).

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:
Depth =
Distance between FLP and RLP
Divider
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:
11.5 ft
Depth =
= 7.66 ft or approximately 7.7 ft (2.35 m)

LIMITED WARRANTY
Digital Control Incorporated ("DCI") warrants that when shipped from DCI each DCI product (“DCI Product”) will conform
to DCI’s current published specifications in existence at the time of shipment and will be free, for the warranty period
(“Warranty Period”) described below, from defects in materials and workmanship. The limited warranty described herein
(“Limited Warranty”) is not transferable, shall extend only to the first end-user (“User”) purchasing the DCI Product from
either DCI or a dealer expressly authorized by DCI to sell DCI Products (“Authorized DCI Dealer”), and is subject to the
following terms, conditions and limitations:
1. A Warranty Period of twelve (12) months shall apply to the following new DCI Products: receivers/locators, remote
displays, battery chargers and rechargeable batteries, and DataLog® modules and interfaces. A Warranty Period of
ninety (90) days shall apply to all other new DCI Products, including transmitters, accessories, and software programs
and modules. Unless otherwise stated by DCI, a Warranty Period of ninety (90) days shall apply to: (a) a used DCI
Product sold either by DCI or by an Authorized DCI Dealer who has been expressly authorized by DCI to sell such used
DCI Product; and (b) services provided by DCI, including testing, servicing, and repairing an out-of-warranty DCI
Product. The Warranty Period shall begin from the later of: (i) the date of shipment of the DCI Product from DCI, or
(ii) the date of shipment (or other delivery) of the DCI Product from an Authorized DCI Dealer to User.
2. 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.

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.
