BEACON TRACKING MODES

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.
