I will admit that I haven't owned a non metered machine for about two years. But as a coin shooter it would seem that in most ground conditions the Golden Umax would be a killer non TID machine. It seems that the Golden posts are few and from the outside it would seem that the Golden isn't as popular as the other Tesoro machines. I would think that it would be one of the top Tesoro coin shooters since it has a 4 tone target ID. Can some Golden Umax people tell me about the performance of this machine and how the variable notch works for them in coin hunting? Thanks.
