g Serious injury or death can result if underground drilling equipment rnakes contact with an

underground utility such as a high-voltage electrical cable or'a natural gas line.

e Substantial property damage and liability can result if underground drilling equipment makes

contact with an underground utility such as a telephone, fiber-optic, watei oi sewer line.

Directional drilling operators MUST at all times:

' Understand the safe and proper operation of drilling and locating equipment, including the use of

ground mats and proper grounding procedures.

' Ensure that all underground utilities have been located, exposed, anci marked accurately prior to

drilling.

I Wear protective safety clothing such as dielectric boots, gloves, hard-hats, high-visibility vests

and safety glasses.

. Locate and track the drill head accurately and correctly during drilling.

. Comply with state and local governmental regulations (e.g., OSHA).-

. Follow all other safety procedures.

Carefully review this manual and the DigiTrak Directional Dritling Locating System Operator's Manual

to ensure you know how to operate the DigiTrak System properly to obtain iccurate depth, pitch, roll,

and locate points.

Prior to the start of each drilling run, test the DigiTrak system with the Transmitter inside the drill head

to confirm that it is operating properly.

Regularly test system calibration while drilling using the ultrasonic function. Always test calibration

after you have stopped drilling for any length of time.

Test system for on-site signal interference. Background noise must be betow 150, and signal

strength must be at leasl250 points above background noise during all locating operations.

FEMEMBER: lf you 31e having difficulty on the job or if you have any questions about

the operation of the DigiTrak System, call DGI's Customer Service O6pirtmentat42S-

Introduction

The DigiTrak Mark lV Locating systgin incorporates significant upgrades that enhance its performance

over earlier Digirrak systems. The Mark lV receivers ind remotei have easy-to-read graphic displays

and menu-driven controls that make using "nO-to.iting easier than ever' You simply use the graphic

disptay to guide you in positioning a tardei ior i fin"i in a box on the display window to locate the

transmitter in the driil head. you can also i;;;i; using ine peak signal or plus/minus signs, as on earlier

DigiTrak models.

The DigiTrak Mark lV system uses the same transmitters, Nicad battery packs, and battery chargers as

t" rrrr-u* llt system. The Mark lV is also available as an upgrade to the Mark lll equipment'

This manual gives information and instructions for the DigiTrak Mark lV Locating System' Many of the

principles are the ,u*L ", in the previous-DigiTrak systems, so we frequently recommend in this manual

that you refer to the DigiTrak Directionat iriiirg Loruting Sy?tem Operator's Manualto understand how

to best operate the system. We have ptouiO"Ji "opy ot-tn" locating system q-anya.l here behind the tab

Telemetry channel setting - Shows the current channel setting for the receiver. The

receiver must be set to the same channel as the remote display. There are four

channel settings (1,?,3,4) and an off setting, which indicaies-that the telemetry

function is turned off and there is no signalto tne remote display.

Locating icon - Represents a bird's eye view of the receiver. The locating icon is

referred to as the "box" when using the target in the boxand tine in the bo\ locating

techniques.

Target - Flepresents the front and rear negative locate points (FNLP and RNLp). When

the receiver is positioned directly above a locate point, the target will be in the box.

L-ine - Represents the positive locate line (PLL). When the receiver is positioned

directly above the PLL, the line willbe in the box. The PLL also allows ior off-track

locating when access over the tool is limited (see DigiTrak Directionat Driiling

Locating System Operator's Manual.

Plus/minus locating indicator * The plus or minus sign in front of the signal

strength value is used_to guide the operator in finding the locate points 1ffulp anO

RNLP) and the tocate tine (pLL).

Signal strength - Displays the amount of signalfrom the transmitter. The signal

strength scale ranges from 0 to 999, where O indicates no signal and 999 indicates

signal saturation (receiver and transmitter are very close).

Transmitter battery - Depicts the transmitter's battery status.

Transmitter temperature - Shows temperature status of transmitter. An arrow

pointing up next to the thermometer indicates increasing temperature; an arrow

pointing down indicates decreasing temperature. A digitaltemperature reading is

displayed below the clock whenever the trigger is held in.

Receiver battery - Depicts the receiver,s battery status.

Transmitter pitch - Represents the inclination of the transmitter (tool). The pitch can

be monitored in either percent slope or degrees. The pitch value will be shown with

the drill tool indicator behind it; the drill tool indicator will point up for positive pitch

and down for negative pitch. Note the smaller superscripied "0', after the "5', in the

transmitter pitch symbol. This smaller number represenis pitch in tenths of a percent

(0-1%) and is only displayed when using sensitive-pitch transmitters.

Pitch/roll update indicator - The dot in the center of the clock should blink every

2.5 seconds, indicating that current pitch and roll inlormation is being received from

the transmitter. This also means that transmitter battery and temperature status

updates are being received.

Transmitter roll - The clock shows the 12 roll positions of the transmitter (tool).

hear three contirmatiJn- b;d; indicating triat ine menu setting has been changed- The display will then

go back to the locating screen.

During locating, to display the transmitter_tempelature.and depth or predicted -dgptt"'., you hold the trigger

in. Before locating vo[ "]ro need to noH tre'iiigger in for l.second at one of the three locate points: the

front or rear negative locate point (FNLp or iN[pi-or the positive locate line (PLL). This is necessary to lock

in on a re{erence signat ;tiength so that the receiver knows where it is with respect to the transmitter'

NOTE: lf you are changing a transmitter, you must reinitiate the receiver (shut it off and power it back up)

after installing the new'tra-nsmitter. you ruit tn"n recalibrate the receiver using either the 1-point or 2-

point technique (see pages 10-1 1).

Locating lnstructions

Handling the Receiver

IMPoRTANT NOTE: lt 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 distance'

Marking Locate Positions

The front and rear negative locate points (FNLP and

RNLP) and the positive locate line (PLL) must be found

and accurately marked during the locating procedure'

To mark a locite position after you have found it, stand

with the receiver level immediately above the locate

point. Look down the verticalaxis that runs through the

center of the display to proiect a plumb line to the

ground. The poini where this plumb line hits the

ground is the location that you should mark.

HINT: lf you mark ihe FNLP and the RNLP' and then

find the PLL, you can determine the exact location ol

the transmittei/tool. lt will be immediately below the

point where the line connecting the FNLP and the

ifNp intersects the PLL. For complete information on

the FNLP, RNLP, and PLL, see the DigiTrak Directional

Dritting Locating System Operator's Manual'

Locating the Transmitter

with the Digirrak Mark lV, you can locate the transmifier/tool and its heading while it moves, whether

standing in front of it, behind t, or toward ine side. You can also locate the tool either facing toward or

away from the drill rig.

The following technique guides you to the tool while standing out in front of it, facing the drill rig' This is

the recommended method for locating. ns vou continue to-drill or as the borepath curves, you may be

facing the last marked locate point rather than the drill rig'

The first position to find is the front negative locate point or FNLP. The FNLP gives you the heading of

the tool and the predicted tool depth. The FNLp's distance ahead of the tool is deperrdent upon the tool's

depth and pitch; the deeper the tool, the further in front the FNLP will be. The FNLP is represented as a

target O on the receiver's display.

Finding the FNLP

1. stand out in front of the tool (facing the drill) at a distance approximately 2 timesthe assumed depth"

2. Hold the trigger inJor t second "no ,"L"i" to locr in the signal, then begin walking toward the drill'

3. As you approach the FNLP, 16. t"tg*tlppeats in the tof lefi corner ot tne display and the signal

strength increases'

Target in the Box

Turn the receiver 90" to the tool's direction, and again center the target in the box by moving the

receiver forward or backward as needed. This is th; FNLP, which is ri,here tn" toot wiil end up if it

does not get a steering command.

With the target in the box, hold the lrigger in for at least '1 second to lock in the signat. During this

time, you will see the predicteo oept[ (with an arro* poinling down to " i"ig;t ahead of the

transmitter) and the ultra.soric height. The predicteo depih is thi depth the tooli"iir O" ar when it

Confirmation of Exact Heading when Tool Deflects Left or Right

Like the FNLP, there is a point behind the transmitter called the rear negative locate point or RNLP'

When the FNLp and RNLP are connected, they make a line that represents the transmitter's heading'

where this line intersects the pLL is the positiori of the tool. using the locate points and the PLL to find

the tool is more reliable and efficient than using the peak signal' T[e RNLP is represented as a target O

Mark lV Remote DisPlaY

The Mark lV remote display screen is configured in the same way as that on the receiver, and it uses the

same display symbols. 'The remote displaf, however, has.a main information screen and then only four

menu opiion* (po*ei on/off, telemetry'cninnet selection, backlight on/off, and hour meteQ- The main

information screen is described below, and then the menu options are explained. Specific information on

remote steering with the Mark lV remote display and its use with a cable transmitter and with a Datalog

mapping system is also included.

Main lnformation Screen

The main information screen shown below is displayed when you turn on the Mark lV remote display unit.

The on/off button on the remote works similar to the trigger on the receiver. The speaker on the remote

warns the operator if the transmitter's temperature is increasing-temperature increases are accom-

panied by tones from the speaker to indicate that appropriate_and immediate attention is required- The

speaker ilso emits tones during the Datalog function when a Datalog reading is received'

Depth Reading When Receiver ls Above Transmitter or pLL

By holding in the onioff button for 2 seconds or more, the transmitter temperature is displayed in place of

the pitch informalion, as shown below. Note that the arrow below the depih reading is poiniing to a target

in front of the transmitter-this indicates that the receiver has the target in the box-and is above the fr6nt

or rear negative locate point (FNLP or RNLP). lf the receiver is over the FNLP, then the reading is the

predicted depth' lf there are no arrows with the depth reading, then the distance is the slant distlnce to

the transmitter rather than the actual depth.

Remote Steering lnstructions

lnstructions for using the Mark lV system for remote steering are given below' ...Please refer first to

,'Remote Steering" unoeitne Remote"Display section inthe" DigiTrak Directional Drilling Locating System

Operator,s Maniatfor instructions on how to set up the equipment.

Once the transmitter is lined up with the receiver, the arrow will appear b9lo1v the depth reading.and,

when perfectly atigned, tn" i"rd.t symbol in the center of the remote steering indicator will blink. lf the

tool gets off course, tn'en tne irrowi to the left or right will start flashing, depending on the direction in

*r,i.fr it has gone ott course. The further the tool goe! off course, then the further to the left or right of the

blinking if the tool deviatis to the left, and ai I goes'further to the left, then the arrows further to the left of

the target symbolwill be flashing.

NOTE: The liashing "c" may appear when not using the cable transmitter if the remote display receives a

very strong signal from a battery-operated transmitter within very close range (5 ft or 1.5 m).

DataLog Function

The DigiTrak Mark lV remote display unit works differently when using the Datalog function than earlier

DigiTrak remote displays. The correct procedure for taking a DataLog reading using the Mark lV system

is given below. Please also refer to the DataLog Operator's Manudl.

1. Press the owrite" button on the Datalog module to place the unit in standby mode, which is indicated

by a flashing LCD on the Datalog module.

At the Mark lV receiver, record a Datalog reading (see instructions on page 7).

The remote display will sound three confirmation beeps when it receives the Datalog information,

and the LCD count on the DataLog module willbe incremented by one.
