Hi, I also have an X-Terra 70. These are not my opinions but what do you think of these letters below from Willy? I hope it is not true, as I have never tried my X-Terra 70 for prospecting yet and obviously not in Tracking doing it. But he does say the X-Terra 70 is a better hunter otherwise which is good.
The reason why I'd like to get an MXT is because it is, basically, a superior detector for prospecting in bad ground. As a coin/ring/relic hunter, the XT 70 is the better detector, but it just doesn't have the 'balls' to deal with bad ground when nugget hunting. I tested both detectors side-by-side and have used both for doing all the above. I now really regret selling my MXT. ..Willy.
Oh, I'd definitely get a large DD coil for the MXT. As an aside, I tested both detectors using elliptical (basically 5x10") DD's and the MXT tracking was fast and accurate whereas the XT 70 really struggled, and often failed, to track the ground. The MXT could also be swung quite fast without problems whereas the XT 70 had to be swung slow.. otherwise the piss-poor ground tracking and slower SAT would cause the detector to go berserk. ...Willy.
For just nugget hunting, the White's GMT will handily best the XTerra 70 and MXT when looking for small gold. The MXT hits harder on 2-3 grain gold than the XTerra70 and will handle bad ground better. The XTerra70 will see smaller gold than the MXT. The XTerra70 IMHO is a better coin hunter than the MXT. The disc. mode on the MXT, though, seems to be more sensitive than the disc. mode on the XTerra70.
Just got back from the Coquihalla river and, while up there, did some side by side in-ground and above ground tests using different sized gold nuggets with the XTerra70, MXT, and GB2. I had a GMT a couple of years ago and base my GMT comments on what I observed using that detector. Overall, as a multipurpose detector, I'd say that the MXT has it over the XT70 in bad ground when prospecting. In better ground the XT70 would get the nod. ..Willy.
XTerra 70 w. 2 coils/rods FS/T (for an MXT)
About 3 yrs old, in good condition with a bit of wear on the touch-pads and a few light scratches on the screen. There's a bit of white silicone on the inner coil ring of the stock coil. Also comes with the HF DD elliptical coil and extra rod. The DD has had the coil cover sealed on around the edge with liquid PVC. $540 USD shipped in USA/Canada. Paypal add 3%. I will also trade for an MXT w. DD and stock coils. ..Willy.
I think I'll hang on to the detector for now.. things to see and people to do; don't want to hang around with thumb up posterior, waiting, when I could be out in the mountains detecting. ..Willy.
