Threshold; Noise Cancel - Minelab Safari Instruction Manual

Threshold

The Threshold controls the audible level of
sound during detecting, or the "background
hum". Most operators find that detecting
with a very low but still audible Threshold is
preferred. A lower level may mask responses
to smaller targets and the higher levels will
make targets difficult to hear. The level preset
by Minelab is 12.
The Threshold range is from 0 to 40.
Tip: The use of headphones will normally allow
the Threshold to be reduced.
Important: While performing a Noise
Cancel it is important to keep the
detector's coil motionless, and also ensure
that no metallic objects are moved in close
proximity to the detector's coil.

In many locations where you will be
detecting there maybe electromagnetic
interference (EMI) which can make your
detector unstable. This instability will manifest
as erratic false signals from the detector,
which makes detecting actual targets very
difficult. To eliminate the effects of EMI you
will need to perform a Noise Cancel by either
selecting it in the menu or by simply pressing
the Noise Cancel button on the control panel
(p. 15).
Whilst holding the detector still, press the
Noise Cancel button on the control panel.
Safari will automatically scan and select the
quietest operating frequency and should run
smoothly once complete. This process takes
approximately 20 seconds.
As EMI can vary over time, you may need
to repeat this process over the course of a
detecting session.
