roll, or heading. You should always perform an electrical interference check prior to drilling.
•
Sources of interference include but are not limited to traffic signal loops, invisible dog fences,
cable TV, power lines, fiber-trace lines, metal structures, cathodic protection, telephone lines, cell
phones, transmission towers, conductive earth, salt water, rebar, radio frequencies, and other
unknown sources of interference.
•
Interference with the operation of the remote display may also occur from other sources operating
nearby on the same frequency, such as car rental agencies using their remote check-in modules,
other directional drilling locating equipment, etc.
•
Background noise must be minimal and signal strength must be at least 150 points above the
background noise during all locating operations.


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.
®
DigiTrak F2™ Operator’s Manual
Introduction
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.

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). This number must match that stamped on the transmitter for proper
communication (see photo of FX transmitter in Transmitter section).

Types of F2 Transmitters
DCI manufactures three different battery-operated transmitters for use with the F2 system: the longrange FX transmitter, the extended-range FXL transmitter, and the short-range FS transmitter. All 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
) 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

The short-range FS transmitter provides a depth range of approximately 15 ft (4.6 m). It measures 8 in.
(20.3 cm) long and 1.00 in. (2.54 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.
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. The FS transmitter requires one AA
alkaline battery.
NOTE: 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.

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 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 F-Series 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.
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.
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.
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

Temperature Updates and Overheat Indicator
F2 transmitters are 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 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.

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.

DigiTrak F Series Display (FSD)
General Description
The DigiTrak F Series Display (FSD) is a multifunction
display that can be used with a variety of DCI receivers. It
provides the drill rig operator with information from the
receiver about the depth, orientation, and status of the
transmitter. The FSD remote can be powered through
either a DC cable source or a DCI lithium-ion battery
pack.
To meet regional requirements and for proper communication, one of the frequency designations shown on the
remote’s serial number label (see photo to the right) must
match that shown on the receiver. The receiver’s frequency designation is located on the serial number label
inside the receiver’s battery compartment (see “General
Description” discussion in the Receiver section.)

Power Options
The FSD remote can be powered by either a DCI lithium-ion battery pack or a 10–32 V DC power source
using the DC power cable. If both a battery pack and the DC cable are installed, the remote will draw
power from the battery until the battery voltage is below the DC source voltage. Install the brace insert as
you would the battery when using the DC cable source (see “Installing and Removing the Battery Pack or
Brace Insert” below).
Connecting the DC Power Cable
To connect the DC power cable, remove the protective cap from the DC power port on the back of the
remote. Then align the four pin holes in the DC
cable with the four pins in the DC power port. Push
in and rotate the cable connector clockwise until the
cable is secure. Install the other end of the DC
cable into the DC power source.

The DCI F Series Battery Charger (FBC) system includes AC and DC power cords, an AC adapter, and
three rechargeable lithium-ion battery packs. 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.
The battery charger can operate from AC (100–240 V, 50–60 Hz, 1.5 A max.) or DC (12 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 approximately 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.

User Serviceability
The temperature of the air around the battery charger should be between
+32°F to +95°F (0°C to +35°C). Charging the battery outside this range may
increase charge time, harm battery performance, or reduce battery life.
It is important to maintain free airflow around the charger, especially near the
top and bottom vents.
If the battery internal temperature is below +32°F (0°C) or above 113°F
(+45°C), the charger will not deliver charge current and will indicate a temperature fault.
The battery voltage should be in the range of 8 V to 16.8 V when inserted into
the charger.
If the battery voltage is above 17 V, the charger will display a flashing red
battery fault indicator and will not charge the battery.
If the battery voltage is between 16.8 V and 17 V, the charger will display a
charge complete status.
If the battery voltage is between 4 V and 8 V, a small trickle charge current will
be applied to bring the battery voltage up to 8 V. If the battery voltage does not
increase to above 8 V within 2 minutes, a battery fault will be displayed and
charging discontinued.
The charger will fully charge a battery in less than 3 hours if the ambient temperature is inside the operating ambient temperature specification.
If the ambient temperature is above or below the operating ambient temperature range, the charger may eventually charge the battery, but the charge time
will be longer than 3 hours.
If charging is not complete inside 8 hours, a battery fault will be displayed and
charging discontinued.
Use the supplied AC/DC adapter or the cigarette lighter adapter cable to power the
charger with DC power in the specified voltage range. Failure to do so could
damage the charger, void the warranty, and cause a safety hazard.
Do not disassemble the charger. It contains no user-serviceable parts.

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.
®
DigiTrak F2™ Operator’s Manual
55
Locating
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.”

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).

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.

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. You can conduct a test for the presence of active interference with your F2 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 F2 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
next step is to conduct an electrical interference/background noise check.
Conducting a Background Noise Check
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. In the figure below, the red flag area denotes an increase in background
noise.

Locating
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.

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, 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.

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.

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.

on the display. The figures below illustrate what you might see on the display and the actual position
of the receiver, transmitter, and locate points. Note that the FLP is ahead of and to the left of the

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, the receiver’s antenna or signal processor
may be malfunctioning. 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.

7. Continue to walk in the direction of the drill or the last known transmitter location. Keep the locating
target on the vertical crosshair and observe that the signal strength is increasing.

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:
11. From the LL, facing toward the drill or last transmitter location, walk forward keeping the target
aligned on the vertical crosshairs.

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

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°) 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.

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 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.
Feasible Target Depth and
Positioning the Receiver as a Target
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, starting with the drill head approximately level, the following
parameters apply:
The maximum depth change is approximately 4 ft (1.2 m).
The maximum pitch change is approximately 14%.
For the most conservative Target Steering operation, we assume that the ideal drill path is a circular arc
with a radius that accommodates the bend radius of most drill strings and products being installed. As
shown in the diagram below, the feasible steering area is limited to the shaded region bounded by the two
circular arcs.

Target Steering
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 or the
last locate points if drilling a curved path. The maximum horizontal distance from the transmitter that the
receiver should be placed is approximately 35 ft (10.7 m).
Programming the Receiver for Target Steering
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.

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 (4.5 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.

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.

DigiTrak F2™ Operator’s Manual
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, 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:
Distance between FLP and RLP
Depth =
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)

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

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.
