I liked it for the week and a half I used it though it didn't do well on the beach so I had to send it back because Fisher Labs said what I described happening in the dry sand was not normal, so I am waiting for the FedX to bring my new one. But on the positive side before I sent it back to be looked at I did run it over an area that I had searched pretty hard with my Tesoro silver uMax and found a 1898 Penny!! So the jury is still out. By the way I don't recommend the electrolysis to clean a dirty penny (could have done it by hand but I was dying to try out the electrolysis. I also found out that these spesial hangers I had were chrome and not stainless steel, and that the copper will transfer to the chrome rod. Thats another post).
