John, the GB2 was among my top 3 finalists in researching gold detectors. The other 2 were the Lobo ST (#1) and the MXT (tied for 2nd with the GB2). No final decision made yet, so all input would be appreciated.
The Lobo ST, btw, was #1 for a few of reasons: Lifetime warranty, optional manual/automatic ground balancing and sensitivity. The only other detector I've had experience with is the Ace 250. I really like the readouts on the Ace and the MXT seems to have similar (but different) readout.
HH, ya'll!
