The G2 GROUND EXCLUDE selling is designed
to cope with even the most
severely mineralised sites. This setting
is marked in red as it is most
frequently needed.
However, you may need
to select either G1 or G3 under the following
circumstances:
Select G2
Lower the search head
to the ground from approximately 50cm away.
If the meter needle remains central and the threshold tone stable then search
in G2 after selecting the desired automatic discrimination.
If, when the search head is lowered, an increase in sound is heard and the
needle deflects
to the right, then select G1.
If alternatively, a decrease in sound is experienced and a left deflection of the
needle then change
to G3.
It is as easy as that.
When operated, this control acts as a memory re-tune bullon as described
under
Tuning (pA). It also indicates which Meter Console mode is engaged
by lighting a red LED over any mode which is on.
Auto Tune maintains the threshold set
by the tune control and is particularly
useful in the first 30 minutes of searching whilst the machine is warming up
or
in adverse ground cOAditions such as the beach.
See Battery Check and Charging (p.3).
