Hi all , I better introduce my-self, Im vanner. I have been reading all I can on the Golden Umax, as it sounds like a neat general purpose detector. Im impressed with it discrimination abilities, particullaly its ability in regards to pull-tabs. I just watched a video clip with " silver53" giving a demo on the beach with pull tabs''', WOW'''' . I would imagine with this ability the machine doesnt even have to run really deep as in sports grounds etc a lot of the jewelry isnt that deep. Ive never used a tesoro before , and I can only imagine that the discrimination abilities are common on tesoros in general....what are your views on the golden Umax. Wife has given me the OK to buy one,, thats all good as long as I dont have to buy her another ring/set
