DISCRIMINATION POINTS
8. Some objects will cause sharp static or "ticking"
when rejected. This is a perfectly normal response
indicating that the powerful discrimination circuitry
of the 1225-X is doing the job.
9. Large pieces of trash such as beer cans or jar lids
may sound like a good target no matter what you
do. With a little practice however, you will be able
to tell the difference between a large target and a
small coin-sized object.
10. The following chart shows some different target
responses you may expect at different levels of
discrimination. Note that as you increase the
discrimination level, you progressively eliminate more
targets including some good ones, such as nickels
and gold rings.
Note: The discrimination levels shown are typical values only and
may vary from detector to detector.

RECOVERY TOOLS
1. A heavy duty, blunt screwdriver is commonly used by
expert Treasure Hunters.
2. A sturdy hunting knife with a 5" blade will do the job in most
soils. A high quality double-edged "survival" knife is an even
better (and more expensive) choice since it will be almost
impossible to bend or break. CAUTION: Using a pocket knife
without a blade lock is a good way to lose a finger!
3. A narrow garden trowel will work in loose or wet soil.
4. Several excellent digging tools are made just for the Treasure
Hunter and especially designed sand scoops are available
for beachcombing. Check with your local dealer.
5. A thin, dull probe is the preferred tool for precise
target location.
OPERATING TIPS
1. We've already said it but it bears repeating: TAKE
YOUR TIME AND OVERLAP YOUR SWEEPS.
2. Use good headphones. You won't miss faint targets,
you won't attract unwanted attention and you won't
bother others.
3. Practice pinpointing. There's nothing sacred about
the methods described in this manual. Many 1225-X
users have developed their own pinpointing methods.
4. Always bury a coin when working in unfamiliar territory
and check it at different discrimination and sensitivity
levels. There may be some sensitivity loss at higher levels
of discrimination. The greater the ground mineralization,
the higher the sensitivity loss. For example, you may
be able to detect a penny at 6 inches deep at zero
discrimination, but no deeper than 4 inches at the pull-
tab discrimination point.
5. The 1225-X is an easy detector to use but if you're having
trouble with any aspect of its operation (pinpointing,
searching, false signals, etc.) go back and reread the
part of this manual relating to your problem.
6. If a target gives a strong reponse in the search mode,
but no response in the pinpoint mode, you may have
"tuned out" your target (and all others) by pushing the
pinpoint button over another piece of metal. If you
suspect this may be the case, move the search coil to
another spot before pressing the pinpoint button again.
7. When in doubt about the possible identity of a target,
dig it up.
