I have only heard of two people here in the U.S that has a Algo Force E1500, and that is Steve Hershbach and one other person the Company sent one to Steve H to get his opinion on the E1500 and Steve H has let a couple of others try the E1500 out I know one of the people that Steve H sent his E1500 to was Gerry in Idaho Gerry's Detectors, go over to Steve's Forum and you can read his opinion on the E1500
Not much on the E1500 here in the U.S as of yet there is a E1500 in NZ that goes by phrunt on detector prospector that has posted quite a bit about the E1500 on Detector Prospector forum, phrunt was the first to receive a E1500 and he can tell you pretty much anything you want to know about the E1500, but he detects very mild ground in NZ
there are several of us here in the U.S waiting for the E1500 to get to the U.S, as far as I know the hold up here in the U.S is FCC clearance and then once that is done they will come to the U.S
