Clark, what were the GC numbers when you balanced?
Me, well, I'm just too new at this machine to make a firm call, but I'm one of those with a "problem" site due to apparent falsing and noise.
I was at my noisy site for about 2 or so hours. During that time, I took a bunch of pics and only dug a dozen or so targets, recovering maybe half because the others were frozen in. I did detect a lot of old iron I did not bother to dig.
I only noticed a lot of noise, I was still able to find targets as a stronger signal or better ID amongst the noise and at a respectable depth for their small size.
Re-reading the manual for the third time, I found I wasn't using Fast Grab correctly, so I was mis-adjusting the GB. Mostly, I didn't spend enough time setting things properly.
Zero disc is just too low to work at this place of mine, as it includes hot rock signals and other junk, it also makes it more susceptible to interferance to nearby powerlines. I know I had that problem, as it was falsing with coil held up in the air.
The coil beeped when bumped against a rock. Back home, messing around with arranging the coil cable and connector, it seemed like that helped the bump-falsing.
I started that hunt with a set of partly run-down rechargeables. Installing Alkalines back home "seemed" better behaved.
I haven't been able to update my findings with any outdoor tests to see if anything helped, as it's just too much like winter out there!
It's back up to zero degrees, a heat wave, compared to 29 below last night. Maybe today or tomorrow I can sneak out quick and try some different settings.
