Searching - Fisher M-Scope 1236-X2 Operating Manual

SEARCHING

Now comes the fun part if you follow a few simple rules. Good
search techniques are every bit as important as a good
detector.
1. The 1236-X2 has two operating modes. The
"Search" mode is activated simply by turning the
unit on. This is a "VLF-Motion Discrimination" mode
that automatically ignores most ground minerals,
rejects junk and works only when the search coil is
moving. The "PINPOINT" mode is activated by
depressing the PINPOINT button and will be
explained later.
2. Set the FREQUENCY control at zero.
3. Adjust your SENSITIVITY control. Only experience
will tell you how much sensitivity to use in any given
situation, but start out at 8.
NOTE: As a general rule, turn your sensitivity down
to reduce excessive false signals caused by highly
mineralized ground or interference caused by
power lines, radio stations, etc. Turn it up if you want
those deepest, smallest targets and you're willing
to put up with a few more false signals.
4. Decide how much discrimination you want to
use.
Figure 7. Keep the
search coil parallel
and as close to the
ground as possible.
