Adjusting the sweep speed.
The speed at which you sweep the coil has an effect on target
response time and Ground Balance adjustment. Matching your
preferred coil sweep speed with the corresponding Motion
setting can reduce noise and improve target signal responses.
Very Slow and Slow
This Motion setting provides a stable threshold, making it ideal
for beginners and most detecting situations. When carefully
detecting a small area, a Slow Motion setting will ensure good
depth and sensitivity. For maximum performance, a very slow
and steady coil sweep needs to be employed when using the
Slow Motion setting.
Note: It is quite important that the Motion setting you select
matches the speed at which you swing the coil.
Medium
This Motion setting will often improve performance if a
more moderate sweep speed is used. Background noise may
increase just slightly compared to the Slow setting, so it is ideal
for the more experienced operator.
Fast (GPX 5000)
Fast Motion is useful when using a fast sweep speed to cover
ground quickly. In these circumstances, a quick sharp target
response will alert the operator to a target. Fast will allow you
to cover more ground in a shorter amount of time.
Note: The Motion speed also effects how susceptible the
detector is to external interference. Basically, the slower the
Motion speed the less interference you will get; resulting in a
smoother Threshold.
If the Threshold is too unstable while you are using Medium or
Fast Motion, you can select Quiet Audio Type (p. 64) or reduce
the Rx Gain (p. 63).
