Pinpointing

In the AUTOMATIC THRESHOLD OFF position, a surface target can appear to be very large,
which is normal. Now the target must be 'narrowed down' to determine its' location more
accurately. Start to pass over the target from one direction, when the meter goes 'off scale' press
the THUMB SET control to its' MOMENTARY position briefly to bring the meter back on
scale. Continue to cross the target in the same direction and repeat the pressing of the switch.
There will be a point where the meter reading and speaker tone will 'peak out' and start to drop
back down. It is at this peak that the front loop is over the buried metal object. Pressing and
releasing the MOMENTARY position of the switch will cause the target to appear to shrink
making pinpointing easier. The AUTOMATIC THRESHOLD allows the pinpointing to take
place automatically.
Locating Caves & Other Voids
1. Set the MODE switch to the CAVE position.
Set the THRESHOLD, SIGNAL BALANCE and the GROUND BALANCE controls to the
NORMAL range. The TONE and SIGNAL BALANCE control may be readjusted to
optimise for the location you are hunting in just as was done for the GROUND BALANCE
METAL MODE.
2. The AUTOMATIC THRESHOLD or the non-motion position may be used. Use the one
that gives you the smoothest performance and is the most comfortable. If there are rapid
ground changes and there is difficulty maintaining a threshold the best choice is
AUTOMATIC THRESHOLD. If you are an experienced user you may wish to leave
AUTOMATIC THRESHOLD off. A constant position with no changes in elevation with
respect to the ground is necessary to avoid false indications.
It is not recommended that you search in this mode unless you are looking for changes in ground
density. Again, make sure that the CS9000 MK2 is maintained in as constant a position above the
ground as possible.
Operation in the CAVE mode will produce a positive sound for all non-ferrous metals such as
gold or silver, and will produce the same response from voids, such as a cave. When a ferrous
target, such as iron, is encountered, the sound will respond by going quiet. The same is true if
there is heavy iron mineralisation.
Since the ground balance is not affected in the CAVE mode, leave the GROUND BALANCE
control at the NORMAL range. Because the ground mineralisation is not cancelled, the CAVE
mode does not achieve the depth that can be expected in the METAL mode.

ACCESSORIES (OPTIONAL)

Headphones

Headphones not only extend battery life but improve Signal Balance by cutting extraneous noise.
The headphones should be fitted with a standard stereo 1/4 inch (6.35mm) jack plug.
