TREASURE IMAGING
Sizing and pinpointing targets precisely
are important capabilities of your GTI
1500. Furthermore, when you press and
hold the TREASURE IMAGING pad, the
searchcoil can remain stationary over your
target. Move the coil around slightly to
try to center it directly over the target.
Targets must pass beneath the searchcoil,
not above it.
The searchcoil must be centered directly
over the target to produce correct size
and depth information. This is especially
important when searching such areas
as slanted walls or the ceiling of a cave.
Targets that are not properly centered may
be indicated as deeper and larger than you
will find them to be after digging.
Here's a tip. For most effective normal
automatic pinpointing: first, place the
searchcoil on the ground near your target,
but not over it. Then, press and hold the
TREASURE IMAGING touch pad. Scan back
and forth across the target, maintaining
searchcoil contact with the ground. You
