Mineralzation and general purpose Garrett machine

I have a couple of questions I hope the folks here can answer. I have been a long time detectorist and owned a variety of machines. One of my favorites was a garrett CX III. It was accurate and fast for coin shooting in towns and country down southern part of the the country. But when I moved back to the rocky mountain region I found it to be a bit iffy in heavy mineral areas of this part of the country. It still worked great as a coinshooter in town and parks but out prospecting or out where minerals were heavy it was a frustrating experience.

My question is this. My old CX III got run over. Yes...my son left it on the ground..I backed over it. No more detector. Anyway. I have been considering the 2500. Style and such is similar to my old grand master but with updates. My concern is this area is heavily mineralized as I said and I dont want to go through the frustration I had with my master hunter if I get the GTI 2500. Or should I get the GTI and then get another detector more suitable for the heavy mineral areas? I can do that but would prefer just having the one detector for now for all around use. That way I can load up on coils and have a coil for all situations rather than several different detectors.

Advice, solutions? Not trying to bring up another detector in this garrett forum, but I have also been looking at the minelab explorer se. My favorite brand of detector though is Garrett, hands down...but as I said...heavy minerals around here and I do need something that can cut through it and the hot rocks.

Advice please.....and thanks in advance
 
The MH was designed to handle mineralization. Did you ground balance it to the soil conditions in your area? The 2500 has a new mineral chip in it to handle mineralized areas but for prospecting I would go with the Scorpion which is also a nifty coin and ring hunter.

The 2500 handles minerals pretty well here in N. Cali and S. Oregon where the ground can be nasty. I have used the 2500 for prospecting and it can go nuts as all VLF's will do in nutty hot ground. I detected a hydraulic mine last year and it ground balanced around 11-12 which is almost maximum and it purred nice and smooth in all metal. And also it is more stable when you use manual ground balance for some strange reason. That area was mainly dirt and exposed bedrock. But the next week I detected an area while nugget hunting and all it was were rocks everywhere, big ones, small ones along a creek and it was so bad I had to stop. Then I grabbed my Infinium and all was well, ha.

I also detected with a guy who had an MXT and his handled the hot ground at Thompson Creek Cali better than my 2500. Very aggressive ground tracking that one has for sure. I think the MH CX Plus would be ok, I think most VLF's have trouble with really hot ground at some point. The Infinium however just purrs through whatever I throw at it. The Explorer is not a prospecting machine by the way, X terra 70 is better for that.

I just got me a Scorpion and havent got to the goldfields yet but so far I'm liking it, the manual ground balance is easier than I thought, but this is just at home so far.
By the way the 2500 with the DD coils is more stable also in hot ground.

Is the GMH III or the GMH plus more stable with the DD coils? Should be (?). I plan on getting one or the other in the near future.
Has any one got opinions on these vs the 2500 ?
I plan on some nugget shooting and cache hunting. I have a XTerra 705 which should be good in the Washington gold areas, but I want the GMH for hunting deeper caches near old cabins that would be close to old mines. I thought because of coil size, a GMH should be able to hit some deeper nuggets.

Double"D" search coils in general are more stable than concentric coils in mineralized ground. So, to answer your question, yes the GMH is more stable with the double"D" search coil. However, the only double"D" search coil still made for the GMH is the 10"x14" double"D"(which is a great search coil). Garrett use to make a 5"x10" double "D" search coil for it, but they no longer do. You MIGHT be able to find one used, but lots o'luck. I wouldn't part with mine.

The 5"x10" search coil is still made and sold for the GTI 2500 as well as the 10"x14". I occasionally use the 10"x14", but the 5"x10" is my favorite.

Best of luck to ya'!:biggrin:Happy Hunting!:)
