The ACE 250 has got to be the best pure coin shooting machine on the market today. Many many detectorists never go beyond the coin shooting stage and for them that is all the machine they will ever need. I have a Garrett GTI 2500 and I am comfortable that it will do everything I ask of it within reason. How does it compare to other brands? I don't really know but it suits me fine. Fisher seems to have a great deal of the high end market in my part of the country and I saw more of them at the Club Hunt I attended than any other brand. There was a couple of kids at the hunt that were using the ACE and they beat me with my $800.00+ machine! All brands claim to be the best, the deepest, the smartest, etc., but I don't know that one is any better than the other. Like someone said, your machine is probably the best to you. JIM,
