Since I've retired, I've had a heck of alot of time to finally do what I've wanted to do for a long time.... Metal Detect the beaches..... So with all those hours out there I'm finally able to take the time when things are slow and the finds are few and far between(and they have been lately). Most of my time has been with the Excal II 10" coil and the SOV GT also a 10" coil but I have loads of time on a Sand Shark and a fair amount of time using the CZ-21 also. Since I was weened on beach hunting with the Sand Shark, it was a natural move to using the other three detectors in Pinpoint/Autotune or what everyone calls All Metal. Here is my definition of a Whisper signal and the three things that so far I have found that causes these signals.... Hopefully those with more experience can chime in with other posibilities or causes of those signals....
Whisper signal (my definition): A loss of, or slight up or downscale variation to the steady (or almost steady) threshold tone.
Here are the three things I have found that are the primary causes of whisper signals for me.
1. The electromagnetic field set up by the coil, does not go straight down but also out of the sides of the coil. So some whisper signals are really just because you have yet to get the coil directly over the target but yet is close enough that the field is disrupted (slightly) and sensed by the detector.
2. The target is a deep target and or may be on edge giving a smaller surface area and the field disruption is different than normal.
3. The target is not deep but indeed a really small target. Metal staples, metal sequins off of clothing, tiny rivets, tiny stud earrings, earring backs, etc. (You can laugh but that is why at night I carry my Pinpointer to find those darn little things in the sand)
In no way would I say I know what I'm talking about here, just passing on what I think I have found from experience that may help out others. Please add to this OR feel free to debate this, it can only make me and others better at what we do.... hmmmm maybe that isn't a good idea.... LOL
