Hey Guys:
First, I wish to thank you in advance for any help that you may be able to provide me and your courtesy.
Recently, I became the proud owner of a Pulse Induction Metal Detector. Being that I've never used a P.I. metal detector and don't know anyone personally who has, I don't exactly know what is expected.
My dilemma concerns the following: Normally a VLF detector has a threshold "hum" that can be adjusted to the lowest volume using the threshold tuning knob. This is of course after ground balancing. What I have noticed while bench testing is that there is a constant threshold "hum" that can be adjusted to a lower volume but there is also what seems to sound like false signals or interference at various pitches. The threshold tuning, frequency adjustment and discrimination doesn't eliminate this. What I'm currently doing is setting the threshold and headphone volume to just about audible and ignoring these signals when performing bench text. Please, advice whether this is expected of pulse induction detectors or its particular to this one.
Thanks Again,
Ernie
