I read a cpl of months back that this unit had a problem or was dis-contniued for some reason, was it corrected and are they back up and still for sale? I am currently using an etrac which I love but it's not the jewelry hunting machine I 1st thought, anyway I like what I had read about the tones and notch capabilities of the golden umax w/new tones. Anybody know what the deal is on this detector? thanks Jimmy in north carolina
