I am still reading here everyday and still learning. I know I am the one that said this is such a easy machine to use, and it is. The hard part is mastering to the greatest potential. I have been doing nothing but working in trashy parks, figured once you learn trash...you would know the coins. Not sure this is true yet but working on this idea. It is a hour or better drive to my so called good locations and just want to be prepared. I have been having pretty good luck all-in-all. Been finding a lot of wheatie, tons of clad..not much silver, but in these worked out parks that isn't bad. I have learned to slow down and listen a lot better. I have been digging a lot more nickels as well. On my nickels they never seem to vary much in ID, if it stays in the 10-12 area it's a good sign. If it hits 8 or 14 at all...it's junk. And no double beeps or stutter sounds...just my experiences. I found a quarter that gave sound only and (--) on the screen. You may have guessed, iron right on top of it. So use your ears. I am digging most of the coins in the 6" range and know the 70 can do better. I was wondering if anyone has any suggestion or hints on the deeper ones. I make sure I get a signal from both directions and if it doesn't vary much on the ID, I dig it. If you are digging deeper coins please share some ideas on what to watch for. Are they sounding good? ID'ing good? I am still using pattern 1 because of the trash and really like it. Also love the 10.5dd 7 kHz and 4 tones. Would love to hear your stories, just luck or what made you dig it? How deep?
