4. Continue the above process until the sound is eliminated. If the sound is not completely

eliminated, then you can fine tune.

For fine tuning, follow the numbers above the symbol and use the + and - switches.

The sound may not be eliminated completely on some types of ground although you have

fine tuned. In such a case, to determine whether you have successfully ground balanced or

not, listen to the audio feedback when lowering the search coil to the ground and when

lifting it o the ground. If both sound the same, it means that the ground balance is

adjusted properly.

After a while the ground balance is completed, the device will switch to the main screen

automatically. If you do not want to wait for this period you can go to the main screen by

pressing and releasing the pinpoint button once.

GROUND TRACKING:

With this feature, the user does not need to make any adjustments. Ground Tracking can

be activated by turning the Ground Tracking switch to 1 position. The Ground Tracking

icon ( ) on the LCD panel starts blinking. As long as the search coil is swept over the

ground, the device updates the ground balance setting. It does not provide the user any

kind of feedback ( such as the ground balance value or the beep sound in the auto ground

balance).

When Ground Tracking is active, the device may emit a loud audible signal if the ground

conditions change (for example a hot rock) or if a target is encountered. In such a case,

sweep the search coil a few times over the spot where you receive the signal. If the sound

continues and the device gives an ID, there is a high chance that it is a target. If the sound

gets weaker or disappears after a few sweeps, it means that that the device gave a signal

for the ground change or the hot rocks.

For better performance, we recommend you to use Ground Tracking in the General Search

mode and not in the discrimination (DI2, DI3 and COG) modes.

Ground Tracking is suitable for fields with dierent types of soils or where hot rocks are

scattered around a large area and not condensed. If you use Ground Tracking in areas

where hot rocks are intensely present, the device may not be able to eliminate these high

mineralized rocks or you may miss the smaller or deeper metals.

IMPORTANT! When air testing, be sure that Ground Tracking is o. Otherwise, the device

will try to ground balance over the target and lose depth.
