ADJUSTING SENSITIVITY
Sensitivity control
The sensitivity bar indicates how responsive the detector is to a
target in the presence of ground noise and/or electromagnetic
interference.
The degree of sensitivity is increased by pressing the top shift
button and decreased by pressing the bottom shift button (on the
left side of the control panel). Pressing the center left shift button
switches between semi-auto and manual sensitivity.
Semi-auto
A line cycling around the number indicates that the detector’s
sensitivity is in semi-automatic mode. In this mode, the detector
continuously monitors the environmental conditions and will adjust
actual detector sensitivity as close as possible to your specified
level of stability, depending on these conditions.
Manual
In the manual mode (where the line does not cycle around the
number) the adjustment controls the sensitivity directly. This mode
is suitable for the beach and very quiet (unmineralized) ground.
Manual sensitivity is also recommended for high trash areas when
best results are obtained by sweeping the coil very slowly.
A high manual number is preferable for stable conditions with low
interference. A low number is suggested for very variable, ‘noisy’
conditions.
Adjusting sensitivity
The highest sensitivity setting (32) is suitable in only the least
‘noisy’, most stable environments. Decreasing sensitivity will
stabilize the detector where it is affected by noise or interference,
but will marginally affect depth penetration and detection of small
objects. This may still be preferable to operating with excessive
background ‘chatter’.
ADJUSTING SENSITIVITY
So that you can detect in best
conditions, we would advise you to
always choose the channel with
least interference before beginning
your detecting session.
If the detector becomes noisy and
you suspect electromagnetic
interference, change to a better
channel before adjusting
sensitivity.
To do this automatically, press the
Noise Cancel shortcut button, or
manually select the least noisy
channel.
