cannot maintain detection sound with the searchcoil
held completely still above your target. This is called
manual pinpointing and for many treasure hunters
proves completely satisfactory.
2. Electronic Pinpointing
Precise pinpointing is an important capability of your
GTAx 550. When you press and hold the pinpoint
touchpad, the searchcoil can remain steady, directly
over your target. Move it around slightly and
maximum sound will be heard when the target is
directly over your target. This increase will be further
reflected in the Upper Scale of your graphic display.
Illumination of the Lower Scale's segments from left
to right will indicate the depth of your target.
For the most effective electronic pinpointing, place
the searchcoil on the ground near your target's
apparent location. Press and hold the Pinpoint
touchpad. Scan back and forth across the target,
maintaining searchcoil contact with the ground.
You will notice an even, more distinct audio sound
when the target is directly beneath the searchcoil's
center.
