METAL DETECTORS – How do I adjust my Sensitivity control to get maximum depth?
A. The Sensitivity control of your detector can affect just the All Metal mode, just the Discriminate mode, or both modes. Its purpose is to decrease the electronic gain of the stage it affects enough to make the detector more usable. If you are uncertain which modes of your detector are affected by the Sensitivity control, just tune the detector according to your operator’s manual, and wave a good target over the coil. If you can detect it farther away with the Sensitivity control at maximum than you can at minimum, the control affects that mode. Regardless of which mode you are using, the Sensitivity control should be as high as possible without causing many false signals or sputtering noises while searching. When these signals are present, it makes hearing the weak responses of good deep targets difficult.
