hi gene. thanks for the good words. i went and bought the 10" magnum coil off ebay for 40 bucks, and it was as though i had bought a new machine. the 10" coil better fits the way that i hunt - lots of fields, woods, and old foundations. i'm willing to put up with some trash. it's a given with any machine.
i don't hunt parks, rec areas or tot lots at all. they don't offer up the types of finds that i like to make. so, when i get good signals out in the middle of a field, or in the middle of the woods, then there's a good chance it's something good... or a shotgun shell. i have to dig all shells, 'cause they sound just like an indian cent, a civil war bullet, or a good button. they're all in the same range.
some people seem confused about the reality of "whisper" signals. they are hard to pinpoint but usually sound off in at least two directions of the "x". it requires a little more patience and digging, but it's worth it. many ignore such signals. it helps to run low disc. and high sens. after a good rain, i'm the first one out the door! hh, and thanks,
