The Chinese are pushing this GFX-7000 detector around the place, i’m going to say it as it is, the coil is crap, the bottom shaft is plastic tube and useless and it is as noisy as all hell. Upon inspection it is an attempt to clone a GPX-4500, some years ago the Chinese managed to get hold of the designs of the 4500 and other things by infiltrating the company by some sneaky means.
Now for the good news, apart from the Chinese screwing up the design, i worked on one of these clones and made it run perfectly, initial tests indicate that it works just the same as a 4500. looks like i will doing some tests out in the field.
