I have been experiencing the following behavior. Not sure if this is normal for this detector:
With all metal mode, ground adjust set to fixed, ground adjust enable toggled, and sensitivity adjusted from approx 3 o'clock to full, an increasingly louder audible tone is heard; almost like a threshold tone. At full setting the tone is so loud it nulls out any detected targets. If the detector is switched from all metal to discriminate, the tone becomes a static spitting sound within the same sensitivity adjustment range. I have tried the detector at several remote locations in case of possible electrical interference and the result has been the same. This is supposed to be a silent search detector. The manual states that some "noise" may be heard depending on interference and ground minerals. But what I am experiencing seems different than this. The detector actually works and I have found quite a bit with it. I just want it to work correctly. Is there is something wrong, out of calibration, etc?
Please advise me if you think there may be something wrong with the detector.
