OK, you are setting up on a site to hunt. The advice is to adjust the gain until it gets chattery and then lowering the gain a notch or so.
Exactly what is used to benchmark the chattery condition?
Is chattery on ground sweeps?
Exactly what is chattery? Gibberish and beeps, bleeps and nonsense I figure. Some of that seems inherent to these things though.
This is never really a well explained procedure in metal detecting 101, it appears(to me) to be an understood term and an understood procedure of tuning for max gain. This may be so elementary to many here that is seems a stupid question, but if you don't ask a question, you never learn. Besides, others might wonder and be reluctant to ask.
Second, when you get that max gain setting, say you are working an area where you will drift toward power lines at some point. Is the max gain setting done twice? Is it done one time, in the EMI area so you cover all of the area with one max setting?
Maybe this will help others besides myself. Oh BTW, I'd never ask this question on that other board. I'd have been fried in oil. That's why I like this site.
Thanks,
Martin
