A MineLab dealer on eBay description of the Go-Find 66
“Minelab GO-FIND 66 Metal Detector ~ ALL NEW & Improved ~ Stronger Build & New Software ~ Waterproof Coil”
Sounds like a much improved Detector.
Just got off the phone with Kellyco and was told they are NOT here, they do not know when they will arrive, and if you have not been on the pre-order list expect another month :-(
