PINPOINTING
During normal detection, the X-TERRA operates
with discrimination patterns. When a target
signal is heard, it is an advantage to identify
the target’s exact position. This is determined
by using Pinpoint
.
Enabling pinpoint instructs the X-TERRA to
temporarily disengage discrimination and
become a non-motion detector. Targets
normally discriminated against will emit a
signal when beneath the coil.
In pinpoint, the detector gives a continuous
audio response as opposed to a single beep
while detecting. This continuous response
indicates the strength of the target signal
directly below the coil.
The pinpoint audio response is tone and
volume modulated. The difference in tone and
volume produced will help in locating the
targets position and depth.

The detector may become noisy if left in
pinpoint. If this occurs, return to normal
detection before trying pinpoint again.
