Yes but it may be best to leave it where it is set. I think this may be a very deep setting once you get the hang of it
General Search (GEN)
Different than the other modes, this mode features a threshold tone which is continuously
heard in the background.
General Search (GEN) mode is used in 2 different ways in the IMPACT: 1) with the Disc. setting
disabled at 0 2) with Disc. enabled (non-zero). When the device is first turned on, Disc. setting
will be off. When the Disc. is set at 0, the device does not discriminate targets and detects
all targets (metals, mineralized rocks etc.). ID of the detected target is shown on the display
(except for negative hot rocks) and the same audio tone is provided for all targets. The audio
tone increases in pitch as the coil approaches the target. This is the typical All Metal mode
found in most detectors.
When using the Disc. Setting in this mode, the device will emit a low ferrous tone for all
targets below the Disc. Setting, and a higher tone for all targets above the Disc. setting
which changes in pitch as the coil approaches the target. Let's say you set the Disc. to 20.
The device will generate a low iron tone for all metals with 0-20 ID and a higher tone for
all targets with 21-99 ID. Upon target detection, the threshold will momentarily go silent
and only the target audio response will be heard. The duration of the threshold's silence is
directly related to the level of the iSAT.
Gain, threshold and iSAT settings in this mode are optimized to provide the best performance on different terrains. You can modify these settings based on ground conditions.
We recommend using the GEN mode when discrimination is not important and not using
it in heavy trash areas or areas containing many hot rocks.
Audio Boost in the General Search Mode
This feature is not included in the settings on screen.
Boosts the sound of weak signals
received from small or deep targets making it easier for you to detect those uncertain
targets. It is recommended that audio boost should be used on a temporary or as-needed
basis because it will not only boost the target signal audio but it will also boost the volume
of ground noise and false signals along with the threshold hum.
Audio Boost consists of 5 levels (b1-b5). At start up, the Audio Boost level is set to low (b1). To
increase the Audio Boost level, pull the trigger and press the minus (-) button simultaneously.
Audio Boost will only work in the GEN mode.
