Howdy,
The ground is too dry to do much hunting at the moment, so on my second outing with the SE (and Pro coil) I chose to hit a nearby site that has produced some older coins, has signal rich areas (aka trash), but has dropped off in finds quite a bit. My goal was to try out various settings and see what I could learn.
So I played with iron mask, all metal mode, ferrous audio, conductive audio, and sensitivity, and some disc. I've searched this place so many times before, I'm pretty familiar where there's 'open' ground, ferrous signal density, and where older coins had been found (widely scattered though).
The thing that seemed most interesting was sensitivity (to which several other posts here also attest). It was like finding the combo to a lock - dialing it in to get it 'just right' for the site. I ran it up to 24-28 to see what would happen, and ran it down to (16-22). I was paying close attention to how much nulling I got over various areas of ground I knew to be more and less signal rich.
The threshold was able to maintain most steadily and recover more quickly from targets when in the 16-22 range (18 seemed OK). With that more stable threshold, bam! out popped a wheat (from a spot I know I've been over, since it was near a landmark old tree). That gave me the bright idea to go back to another signal rich area I had tried just before then, but had been using sensitivity cranked back up closer to 26 or so. Literally not more than five minutes after lowering the sensitivity to get a steady threshold, signals started coming through more cleanly, and bam! another wheat. Again, right from a spot I've scanned several times in several manners before with my other detector/coils.
My takeaway seems to be consistent with other postings, in that some ('normal') nulling is due to discrimination (if any is set), but constant, unrecovered nulling may indicate sensitivity being too high. From other things I had read, I was expecting to hear lots of chirps and erratic tones to indicate too high sensitivity, but with disc set, too much nulling may be the indicator. I wasn't able to get a sense for how much (if any) depth might be rolling off between sens. at 16 vs. 24+.
Comments? On track here? I'm enjoying learning the new detector (although very familar with detecting). So much ground to retrace... doh!
(p.s., the wheats were a 1951 and 1920, remarkable only in being found after having eluded me before, so no pics).
