The Basics of Metal Detecting
Make sure the detector tube is adjusted to a comfortable length.
Sweep the searchcoil from side to side in slow, overlapping motions.
Keep the searchcoil parallel and close to the
ground. Overlap each sweep to get the best
possible coverage. The Junior T.I.D.
requires searchcoil motion to
properly detect buried
targets. If the searchcoil is
held motionless over a
target, the detector will
not detect the target.
Try not to lift the searchcoil at the end of
your sweeps. This may be difficult for
younger children, but the closer the
searchcoil is to the ground throughout the
sweep, the more likely you are to find
buried metal objects.
You may want to adjust your discrimination
during your search, depending on what you
are finding. For instance, if you are
searching with all three target categories
active, you will detect all types of metal
objects. If you find that you are in a trashy
area with a lot of iron objects, press the DISC
button to eliminate the iron category. If you
are in a trashy area with a lot of pull tabs and
bottle caps, press the DISC button again to
eliminate the middle target category.
CAUTION: Be aware that some desirable objects, like nickels and gold, are
eliminated from detection in the middle target category range. Gold rings
have a metallic signature similar to pull-tabs; nickels have a metallic signature
similar to some newer pull tabs. It requires practice and patience to
understand what types of objects are eliminated at each setting.
CORRECT
WRONG
Sweep the searchcoil in a half-circle
movement as illustrated here. Repeat
this motion every step you take to
guarantee that the area is being
covered thoroughly.
