Just got back from a short 3 hour hunt in a "worked out" park. One 1919 wheat, 1897 Indian, 1889 V nickle, 3 Barber dimes,1900,1905-O, and 1912D. This is an amazing machine and over the last year I just get more amazed every time I go out. Used the Pro coil on everything except switched to the 6x8 SEF and got the 1900 dime and the Indian out of the same hole in high trash that I have hit several times before and just never heard it. This is the best machine I have owned in 30 years of detecting. Wonder why all my detecting buddies don't want to go anymore?
