As snowmelt commenced today, I decided to go into my own yard, in some areas where the snow was gone completely, and give the machine a run under "better" conditions. I live in the country, in a small neighborhood recently developed on property which was farm/ranch land prior to this. This fact plus some detecting I had done in the past had me pretty convinced that away from the house itself, where nails and construction debris reside, there would be few targets, and EMI should be low.
I tried starting up the unit at disc 6, 4-tones, thresh 0, sens. 70 and then ground balanced; ground phase was mid 60s with the 10" elliptical concentric. After ground balance, with these settings, the machine was INCREDIBLY quiet. TOTALLY different than before. So much so, that I raised sens to 85 and threshold up to 3, and still quiet as a mouse. I actually thought it was not working properly
, so I ran it over my boot just to make sure the metal lace guides registered! Obviously, EMI and tons of trash were a big part of the cause of my "brain overload" at the mid-city park I chose for that first F70 hunt.
Now, I didn't recover many targets, mainly because I didn't want to dig a million holes in frozen soil to recover nails. I found a couple of patches of ground where I'd have several iron hits per sweep (probably nail spills), sort of like I had at the park, but mostly just an occasional hit. I dug a screw which was bouncy but mid tones, and an aluminum beer can which was a hard-hitting near 70 tone. It pinpointed to 2", and when I had dug to 4 and had not recovered the target, I figured it was a larger aluminum piece. Sure enough, it was. I was really, really encouraged that in this environment, I was able to make sense of the machine and what it was telling me. I feel MUCH better at this point. Thank you all so much for the help and encouragement.
I think I'm really going to like this machine once I really learn to "drive" it!
