Searching - Fisher 1280-X Aquanaut Operating Manual

SEARCHING

Good search techniques remain the same whether you're using
your 1280-X in the desert or on the bottom of the ocean.
1. Decide how much discrimination you want to use.
a. In relatively non-trashy areas you may wish to search
at zero discrimination. In this manner, your 1280-X is
at its most sensitive and will detect all metal targets
within its range. Once an object is detected, you
can increase the discrimination level for further target
identification.
b. In trashy areas, it is generally easier to search at a higher
level of discrimination (at the pull tab discrimination
point for example). This way you will detect mostly
good targets and can lower the discrimination level
for pinpointing (zero discrimination will produce the
strongest signal on small or deep targets).
2. Search slowly and systematically, sweeping in a tight
semi-circle.
3. Keep the coil parallel to, and as close to the ground as
practical.
4. Overlap your sweeps at least 50%
5. Search in a methodical manner. Pay close attention to
where you're going and where you've been.
6. Keep the searchcoil moving at a comfortable rate.
NOTE:
Other motion detectors may require a very rapid sweep for
Figure 6. Keep the
coil parallel and as
close to the ground
at all times
