decreases the sensitivity (depth of detection) of the detector,
thereby increasing the possibility of missing minimum metal
mines.

From the default (middle) V/S setting, it is possible to increase or
decrease V/S levels in five steps. Regardless of the V/S level
selected, the volume of the Threshold Tone will remain the same.
For safety reasons, the V/S setting will always commence at the
default (middle) setting every time the F3L is switched on. The Test

press and release the Volume/Sensitivity button the required
number of times (maximum five times from default level). During
each button press, a short high-pitched tone will be heard. When
the maximum V/S level is reached a long high-pitched tone will
be heard.
b. Decreasing Volume/Sensitivity. To decrease the V/S level,
press and release the Volume/Sensitivity button the required
number of times (maximum five times from default level). During
each button press, a short low-pitched tone will be heard. When
the minimum V/S level is reached a long low-pitched tone will be
heard.

V/S setting has been adjusted, it can be restored to default level
