It did great i found 126 silver coins and 10 tokens, i ran my sens at 8 and had no interference with any of the 90 or so detectors that were out there,the 30 ran smooth as could be. this was my second hunt ever and im hooked,I also met joe demarco there and he is a great guy definatly top notch. the 30 is a very capable machine, I cant wait to try the 70. hh johnny nj
