I'm still playing with mine, so, the jury is still out. So far, not a big fan, but, I need to put in more hours before I decide if it's something I want to use or not. I've used a few PI machines before and didn't particularly care for them. I just spent too much time digging iron junk. I figured this would be better because it's supposed to have some discrimination, but, so far, I haven't found it to be reliable enough to ignore "bad" signals. Still, if it will find gold deeper than any other machine, that's pretty much what I bought it for. So far, I haven't found any good target that my other machines wouldn't have found. Deep iron, sure, it finds that junk 2 feet down, but, that's not what I'm looking for. The lower clevis just broke a few days ago, so, it's down at the moment until the new one arrives. Also, the factory battery life sucks. Fisher says it will get 3 1/2 hours on a charge, which is kinda pitiful this day and age, but, I knew that from the start and could live with it......if it actually got that. The problem is, I haven't even got 3 hours of use time yet, even though the battery has been cycled many times now. I did manage to get a custom long life battery for it, and it's sitting here waiting to go on it's maiden voyage as soon as the lower shaft gets here.
