A target at 3” will sound like a target at 12” because the signal is either
there or not…. Sort of like a light switch being on or off. When you hear a
loud beep, don’t assume it’s shallow. If your target repeats nicely but
disappears when the coil is lifted a few inches off the ground, your target is
either deep or very small. A coin size object that is only 4” deep will still
sound strong even if your coil is 6” above the ground. Bury a coin and
practice this technique for probable depth.
Less is more with your BLISSTOOL when it comes to
GAIN
and
DISCR
DEPTH
. Don’t be concerned if your BLISSTOOL only operates well at a
GAIN
of “1”. You will still be going very deep. When in Virginia, detecting
the Culpeper red dirt, we heard a deep signal with our
GAIN
set at “1”. We
turned the
GAIN
up to “5” and the signal disappeared. It ended up being a
round ball at about 12” deep. That old analogy applies here; too much
GAIN
in bad dirt is like turning on your hi-beam headlights in the fog.
If you need to run at a low
GAIN
level, make sure your
DISCR DEPTH
is
not too high - otherwise deep non-ferrous signals will “break up”. (see Chart
on page 8).
Wrap the cable as shown using the Velcro ties. If the cable flops around
loosely, you can get false signals.
