Just got a new M6 and went to a construction site this morning. Was able to find a worn Standing Liberty 25 cent piece and a 1902 Indian. Also found a token Good For 5 cents in Trade. Not alot but I can tell I like it so far. The site was littered with iron and trash. I had no problem with identifing almost all targets before I dug. I've used alot of detectors in the past 15 years, to many for sure but so far I'm very happy with the M6. I also would like to see a M6 form. Happy Hunting To All! Joe
