Im tired of not getting Indianhead pennies,the etrac is not doing its job picking up deep coins.And Indians are deeper thanever because of 100 years of rain and storms anyways to get back to what I was talking about.Is there such a machine out there that has a certain number for Indians only,like for instance I wanted to hunt a 150 year old farm and I wanted to discriminate out everything except Indians I know its sounds crazy.Positive feedback would be appreciated.
