SEARCH TECHNIQUES (continued)
The T
2+
’s other # OF TONES selections have a reputation for lightning-fast response over
targets, with the result that the duration of the sound over a good target can be very short,
especially in a trashy area.
bP
lengthens the duration of the target’s sound. Many users will
find this audio feedback less fatiguing.
bP
makes it easier to listen through the trash clutter to hear good targets. Whereas in
2+
slowing your sweep speed leads to a loss of sensitivity,
bP
allows you to sweep slower,
without a loss of sensitivity.
In areas which have been
pounded to death
and were seemingly
hunted out
, even by the
predecessor version of the T
2+
,
bP
can make such sites productive again. By detecting targets
which were just out of reach of other machines, or by lengthening the duration of good sounds
that were too hard to hear amid trash sounds, old sites are again productive.
Most of the foregoing techniques apply both to the Discrimination Mode where the process is
selected, and to the corresponding All Metal Mode, whose response characteristics are also
modified when
bP
is selected.
While searching using
bP
, you may also want to periodically toggle back to the standard
2+
selection. Press-and-Hold the MENU button to temporarily engage the standard
2+ selection
.
For users familiar with the T
2
2+
setting,
bP
may identify targets more accurately. Targets
yielding a marginal response in one # OF TONES setting may sound different in another
setting. If you are new to the T
2+
, toggling back to
2+
from
bP
, using the MENU button, can
serve as a learning tool to understand the different response characteristics of the different
selections.
Pinpointing With the Trigger Switch
When you turn the
T
2+
on, the ground cancellation setting is preset to give a positive response
on nearly all soils. This means that if you are pulling the pinpoint trigger, the audio tone will
get louder as you lower the searchcoil to the ground. But you do not want to hear the ground;
you just want to hear the target. So always Ground Cancel first.
After you have discovered a buried metal target using the ALL METAL or DISCRIMINATION
Modes, use the trigger switch to pinpoint its exact location.
Position the searchcoil an inch or two (2.5-5cm) above the ground, and to the side of the
target. Then pull the trigger. Now move the searchcoil slowly across the target, and the sound
will communicate the target’s location. As you sweep from side to side, and hear no sound at
the ends of the sweep, the target is located in the middle of that zone, where the sound is
loudest and the audio pitch is highest. If the sound is loud over a wide area, the buried object
is large. Use the PinPoint feature to trace an outline of such large objects..
