TARGET RECOVERY
Once you have pinpointed a target, your objective is
to recover it quickly and neatly, leaving no trace of your
excavation. There are almost as many ways to do this as there
are Treasure Hunters. Whatever works for you is good enough as
long as you don't break any laws, damage vegetation, or leave
your search area looking like a World War II battlefield.
Generally speaking, beachcombers do little if any damage to
the environment while recovering targets. However, if you plan
to use your 1225-X on lawns or in parks, your target recovery
method can be very important. Two of the most successful
methods are illustrated in a separate booklet enclosed with your
1225-X.

your 1225-X will not be

your swings.

Note:
Depth is also determined by the size, shape and material of
the target as well as the degree of ground mineralization and
sensitivity setting.

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 1225-X has two operating modes. The "Search"
mode is activated simply be turning the unit on. This is a
"VLF-Motion Discrimination" mode which 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. Adjust your SENS control. Only experience will tell you
how much sensitivity to use in any given situation but
start out at 8.
As a general rule, turn your sensitivity down to reduce
excessive false signals caused by highly mineralized
ground interference caused by power lines, radio stations,
etc. Turn it up if you want the deepest, smallest targets and
you're willing to put up with a few more false signals.
3. Decide how much discrimination you want to use.
a. In relatively non-trashy soil use a low level of
discrimination (2 for example). In this manner the 1225-
X will detect all metal targets within its range and you
can instantly increase the discrimination for further
identification.
b. In trashy areas you will probably want to operate at a
high level of discrimination (6 for example) to cut down
on the amount of time you spend digging bad targets.
4. Keep the search coil moving at a comfortable rate.
Remember that the 1225-X is a motion detector and
responds only when the search coil (or the target) is
moving while in search mode.
5. Keep the coil parallel to, and as close to the ground
as practical. This is important for maximum coverage
and depth. If you are hunting on a lawn you can set
the coil right on the grass and search.
6. Overlap your sweeps approximately 50%.
7. Search in a methodical manner sweeping in a tight
semicircle. Pay close attention to where you're going
and where you've been.
