I found a sneaky little spot tucked away in a wooded section of a park that had major traffic, there must be a signal every inch literally for about 40 x 250 feet! And there are high tones everywhere and some are definitely old can tops and bigger junk along with the densest tab infestation I have ever found,my Ctx was going nuts partially because I had the 17 inch coil on it so I kicked the leaves aside and was shocked to see several older blackened 1970s clad quarters dimes wheats memorials ect.. and tabs everywhere right on the soil surface, no digging needed! , i said to myself I was going to cherry pick a few high tones and come back with my Deus anyways so I didn't hang around there long.. didn't find any clad later than 1976 it was all just under the surface litter,and I'm almost certain it was never hunted due to the location being abandoned around the early to mid 70s and the trash density being too much for the technology of the era when it would have been possible to hunt it before the undergrowth made it almost impossible to hunt for years until recently, i have been in every major park in my area for years and I have never heard anything like this, depth isn't an issue yet just separation, any help would be greatly appreciated! I really need to read Andys book! Thanks! Rich
