Salt Mode Anomaly
Normally in Pinpoint mode all targets will produce an audio
response as well as the screen response. However, targets that
are
below
the ground balance point will produce nulled audio
response. In normal ground, this is not a problem as targets are
never below the ground balance point
5
. But in saltwater hunt-
ing, the ground balance point can be close to a VDI of 0, mean-
ing that the entire iron range could be below the balance point.
If you are saltwater-hunting and find that a target “disap-
pears” in pinpoint mode, it is likely below the ground balance
point, and it is likely iron. You will notice, however, that the
Pinpoint bars still properly respond to the target, so you can still
pinpoint it and dig to verify.
