RB, I hope you don't mind a few more questions. (hiopoefully pretty soon I'll be able to supply a few answers.) I haven't been able to download your program, but I set one one for my little iron patch where I'm certain some things are still hidden deep down. Hopefully you can kick the tires on these settings for me, as today I have only been sucessful in finding in the iron strewn area one small brass eyelet about four or five inches down, and a very tiny copper shoe tack at about the same depth. Sadly, they were both my stellar signals! Anyway, this is how I've got it set for what I hope will unmask the deep stuff mixed with the iron:
threshold straight line 27 with the nail pattern combined
sensitivity manual 24
gain 24
response long
sounds ferrous (no of tones 2) .....when in conductive, the sound is all over the place, and ferrous 2 tone seems at least give to me a clue when over the bigger iron..
variability 29 ...trying to knock out that high square nail iron screamer on 30
limits 30
pitch 15
deep on
fast on
trash high
ground difficult
You'll probably see a mistake in this setup immediately. What I am getting (hearing) is frequently the higher pitch resembling non-ferrous, immediately followed by a slight "thud" which sounds like what you'd hear with iron. (there is iron virtually everywhere). I even heard the "thud" on the shoe eyelet and tack though these were ever so slightly cleaner, and both those signals were in one direction (as virtually all potentially hopeful signals are in one direction over this area). If the pattern and settings seem reasonable (I've used conductive with even more apparent falsing also) then I'm probably at the end of the road for this patch until the six inch coil arrives. (I'm going to wait until I use the small coil before I start pulling out the iron, as my purpose on this patch is to actually see if refined settings can beat this iron) Please let me know what you think of the settings for this task. For instance, considering how contaminated this spot is, I'm not sure if "fast" and "deep" are helping, or are compromising the clarity of my signals even more than they already are compromised? Thanks, John
