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 diff erence 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.
Once the approximate target location is
known, move the coil outside of that area
and press
.
PINPOINT
Sweep the coil over the target location. The
menu scale segments on the LCD indicate
how close the target is to the center of the
coil. The detector will only produce a high
volume when the center-ring of the coil is
directly above the target.
Taking note of the detector's response, reduce
the span of each successive pass of the coil
until you are confi dent of the target's location.
Make a mental note of the position or, if the
ground is sandy, mark a line with your shoe
or a digging tool.
Move to one side so that you can pass the
coil over the target at a right angle to your
initial direction. When the detector sounds
you should know exactly where to dig.
