Pick Magnets And Control Boxes

[Skookum]

Here is a question for people who have had years of experience with using, selling, or engineering detectors.
Has anyone ever heard if strong magnetic fields, say from a rare earth magnet on a pick head, bumping into contact with the control box have any potential for altering a detector’s performance?
I didn’t think of this until I was scratching my head trying to figure out why I kept hearing lightning spikes on an otherwise on a crystal clear day. 😅

When I got my Gold Bug Pro (August 2015) I read (in the manual, I think) about not getting a magnet close, but that vague comment was all I found.  So I emailed First Texas requesting more detail.  I don't think the person who responded even identified him/herself, but s/he asked one of their engineers and the reply relayed to me was that it could damage the speaker; otherwise not an issue.

I don’t worry about the magnets snd the detectors. Keep super magnets away from your wallet, unless you’d like all those magnetic strips erased.

No probs with magnets near the electronics coz there's no emission from it....magnets are passive. But I have noticed that my 6000 reacts to my pick being dropped onto the ground a lot, especially if it falls on a quartz rock....now thats sensitive!
