anyone have a sunray on their GTI series? i was wondering what kind of depth ya got outa the sunray, it says 3-4 inches on coin sized objects but thats the dealer talkin, i was wondering if it actually gets that depth out in the field. i'm on the fence if i wanna cash in my clad and get one. i really like the idea that it uses the discrimination from my detector plus works off my headphones and my detectors power supply. decisions...decisions..:doh:
