OVERVIEW
The 750 Tracker performs well with a variety of beacons and can
track shallow or deep bores. It can send beacon information to a
display mounted on the drilling unit operator’s station. The 750
Tracker can also locate lines and cables. Available modes are 8
kHz active (when used with transmitter) and 60 or 50 Hz passive
(for locating power cables).
A brief description of the buttons and display on the 750 Tracker
follows.

The 750 tracker has four operation modes: tracker control,
walkover beacon tracking, remote guidance, and line locating.
Potential radio frequency (RF)
hazard. Operating this device within 4 in (10 cm) of

IMPORTANT: Large metal objects, rebar, power lines and any
other kinds of interference can adversely affect depth estimates.
BEACON TRACKING MODES
Set-up
You must calibrate tracker before beginning a beacon tracking job.
After calibration, tracker can estimate depths from approximately
9 in (0.2 m) to 100 ft (30.5 m) depending on beacon used. Keep
the following in mind when calibrating system:
•Beacon and tracker should not be moved or rotated until
calibration is complete.
•Only depth estimation is affected by calibration. Roll, pitch,
left/right deviation, temperature, and battery status are not
affected.
•Large metal objects, rebar, power lines, and any other kinds of
interference will adversely affect calibration.

Calibration Procedure
1. Install beacon into
toolhead and place on
ground exactly 10 ft (3 m)
away from tracker. Make
sure no metal objects
including drilling unit and
drill pipe are within 20 ft
(6 m) of tracker and
toolhead.
2. Position tracker parallel to
center of toolhead.
3. Turn tracker on and press
and hold depth and up
arrow keys until calibration mode is entered. Release keys.
4. Verify calibration by moving tracker 15 ft (4.5 m) away from
toolhead. Check depth. If reading is not 15 ft (4.5 m),
recalibrate tracker.

Tracker Control Mode
Overview
Incorrect procedures could result
in death, injury, or property damage. Learn to use
equipment correctly.
This mode allows 750 Tracker operator to disable hydraulic
power to drilling unit thrust and rotation within 16 seconds. This
mode will not stop thrust and rotation immediately.
When tracker and display communications cease, green tracker
control light on drilling unit will come on and thrust and rotation
will be disabled.
Troubleshooting tip: If thrust and rotation do not work, check
whether tracker control light on drilling unit is on. If it is,
communication has probably stopped between tracker and
display or tracker is set to incorrect code. If communication
cannot be restored, install tracker control key on drilling unit.
Tracker control light will go off and thrust and rotation will
function.
IMPORTANT:
•Tracker operator cannot stop thrust and rotation from tracker
with tracker control key installed in drilling unit and turned to
disable position.
•Tracker control mode is available on units with “TC” at the end
of their serial numbers.

ground.
5. Turn off tracker. After 8-16 seconds, tracker control light on
drilling unit will come on and hydraulic power to thrust and
rotation will be disabled.
6. Change downhole tools.
7. If you are tracking backreamer’s path, turn on tracker and
enable code transmission. After 8-16 seconds, tracker control
light on drilling unit will go off and thrust and rotation will
function.
If you are not tracking backreamer’s path, install tracker

Walkover Tracking Mode
Location
1. Turn on tracker. Make sure you can see fore/aft arrows in
center of display. If you see left/right arrows, press fore/aft/
left/right key.
2. Walk bore path with bottom of tracker parallel to beacon. Do
not hold tracker at right angle to beacon.
IMPORTANT: A common problem when locating a beacon is
secondary or ghost signals. A typical beacon signal pattern
shows a main signal and two weaker secondary signals.
Track beacon at main signal. Familiarity with beacon signal
pattern will lessen the effect of secondary signals. Also, the
beacon tracking arrows will disappear when tracker is over
secondary signal.
3.When both fore/aft
arrows are on, sweep
tracker from side to side
and use signal strength
display to find lateral
location of beacon (point
A).
4.Step back until ghost is
located (no arrows in
center of clock face and
low signal strength) and
then move slightly forward
until only one arrow is lit
(point B).
5. Press fore/aft/left/right button to switch to left/right arrows and
sweep tracker back and forth until both left/right arrows are
on.
6. Switch back to fore/aft arrows and move forward until both
fore/aft arrows and target is lit.
7. Take depth estimate and mark spot.

Remote Guidance Mode
Information is transmitted directly to display at drilling unit when
tracker is in remote guidance mode. Approximate distance from
tracker to beacon (not the estimated depth of the drill head) is
shown every 5 seconds.
Distance will not be correct within one and a half times the
toolhead depth. For example, if you are drilling at 4 ft (1.2 m), you
will be able to drill within 6 ft (1.8 m) of tracker.
To operate in remote guidance mode, place unit in stand while it
is turned off. Press and hold mode button while pressing on/off
button.
Tracker and drill head can be up to 60 ft (18.3 m) apart when in
remote guidance mode. IMPORTANT: Do not drill past tracker.

Displayed Information
Beacons send a variety of information to tracker. All Subsite
Electronics beacons send pitch, roll, temperature and battery
information.
Roll
Beacon roll information is useful in determining the direction that
the drilling tool will tend to travel when pushed without rotation.
The following chart shows typical tool face roll indications for
directional drilling.
Depth
To estimate beacon depth, press depth button. Estimated depth
to beacon will be displayed. To change depth units, press depth
and mode buttons.
All tracking and locating systems are subject to interference. To
quickly check for interference, raise tracker 1 ft (0.3 m) and make
second depth estimate. If the difference between the two
estimates is not 1 ft (0.3 m), there is interference.
