TARGET PINPOINTING

(no-motion PINPOINT mode)

After you have identified a target using a motion mode of detection,
press 

to identify the target’s exact location. This technique can

yield more information about the target’s shape and size and also find
its exact location to facilitate excavation.

1

1.. Position the searchcoil just barely off the ground, and to the side of

the target.

2

2.. Press and hold 

and raise the searchcoil about 2 inches.  Lifting

the searchcoil away from the ground makes the ground signal go
negative, so the machine is silent. 

3

3.. Now move the searchcoil slowly across the target, and you can

locate it by the sound.  The target is located directly under where
the sound is loudest.

1..   To narrow the response further, position the

center of the searchcoil near the center of the

response pattern, but not directly over the center.

2

2..  Release, then press and hold again

again.

3.. Repeat this narrowing procedure to narrow the

field of detection further.

e::  Depth indication is less accurate after

narrowing.

If you keep

depressed for continuous searching,

realize that drift will occur over time, causing the

detector to gain or lose sensitivity. Periodic

retuning of the detector is required to

minimize drift; release and press

to

retune.

●

Position detector upright.

●

Rotate the LOCKING COLLAR fully in the
counterclockwise direction.

●

Insert your finger inside the tube and make sure the
INTERNAL CAM LOCK is flush with the inside of the tube.

●

Insert the MIDDLE STEM into the
S-ROD, with the SILVER BUTTON
pointed upward

●

Rotate the MIDDLE STEM until the
SILVER BUTTON locates in the hole.

●

Twist the LOCKING COLLAR fully in the clockwise
direction until it locks.

●

Repeat this process on the LOWER STEM.

●

Using the BOLT and KNURLED KNOB, attach
the SEARCHCOIL to the LOWER STEM.

●

Adjust the LOWER STEM to a length that lets you
maintain a comfortable upright posture, with your arm
relaxed at your side, and the SEARCHCOIL parallel to the
ground in front of you.

●

Wind the CABLE securely around the STEMS.

●

Connect CABLE PLUG to housing.
Do not twist the Cable or Plug. Turn Locking Ring only. Use
minimal finger pressure to start the threads. Do not cross-
thread. When the Locking Ring is fully engaged over the
threaded connector, give it a firm turn to make sure that it
is very tight. When the Locking Ring is fully engaged over the
threaded connector, it may not cover all of the threads.

●

Tighten both LOCKING COLLARS.

Note: Very tall users can purchase the optional Extended Lower Stem (TUBE5X), for extended reach.

Forcing in MIDDLE STEM with CAM LOCK raised may form a burr on
camlock. If this happens, remove burr with knife to allow insertion.

If you wish to change the
position of the armrest, remove
the screw and move the armrest
to one of the alternate hole
locations.
