Silent searching in All Metal- G2

[Giantprawn60]

Hi guys, so I started experiencing with AM (i'm more of a Disc kinda guy) but don't seem to see any difference between being at -5 / -10 and being at " hum" level, in terms of depth (both air and ground). Is it really much better,according to your experience, to be in "hum" level when in AM?

The way I hunt in all metals (almost any machine) is to crank the sensitivity (gain) 'way down, adjust threshold hum to a comfortable background listening level, and then crank the sensitivity/gain control up until the background noise is clearly audible in the hum but not to where it starts to get choppy.

Then, of course, ground balance. If the ground turns out to be too noisy, then crank sensitivity/gain back down until the ground noise is tolerable and is not driving the background hum silent. And pay close attention to maintaining good ground balance while you search.

If either the threshold control setting or the signal noise pushes the background (no target) sound down into the silent region, you can be walking over weak signal targets and not hear them. This is why all metals searching is normally done with a continuous background hum.

Thanks Dave. Your the best buddy. I'll have to try that when the 30" of snow melts on my civil war camps.

Just use it in Snow mode.

Geez this is what I'm getting at. I'll take everything you have to offer oh great one & I'm serious about that. We do love you buddy. I'm hanging on your every word. Thank you for telling us pointers.

This is bull crap. I can't detect. Just saying guys.

By the way I shoved that by hand. I'm sore as heck.

It's cool I'm used to digging that deep with a FT machine.

Thanks Dave, that makes sense. So if i'm in the silent region I may be losing targets as they can be "masked" by the ground, correct?
