I have a Garrett Super Sniper coil that fits the GTP / GTAx series - Note: it does not fit the early production models of GTAx 1000. Please look at pictures and make sure your connector is the same as this coil. Coil is in excellent condition; it was only used once on my 1350 GTP. I sold the detector and now have no use for it. Price is $65 shipped or would trade for a White's Blue Max 350 (Black Version), or a White's 5900 or 6000 control box (SL Black version only - and does not have to work but must be complete).
