GMT for tot-lots/wood chips?
- Thread starter ToniSteve
- Start date
so I wonder if what you read was a forum post about someone using a GMT King Cobra or GMT-1650 or GMT Cobra, etc., for working the playgrounds?
Those GMT references are for the long discontinued Gold Mountain Technologies brand. A short-lived resurrection of the out-of-business Gold Mountain metal detector company. THOSE GMT models would be OK picks for working playgrounds.
Of the models you have, your modified IDX Pro and Toni's M6 would be two very good models work tot-lots. I was just out this morning with the MXT-300 w/5.3 Eclipse coil for a little bark-chipping and managed about 80+ coins so far. Most were close to the pipes and other structures (metal) where others either used too much discrimination or (mainly) didn't work them properly.
The "nugget-specific" models are not good choices for general coin hunting tasks because they lack needed discrimination.
Have you and the family been out again? Having any success?

Hello Monte,
Yes we have had some fun! We still haven't tried for the ring yet, those folks are to busy with there strawberry fields to mess with it now. I want to video the whole thing. I am still having fits with ground balancing the XL Pro. I will get down there one of these days and hopefully catch up with you so you can take a look at it.
That post I mentioned was specific to the Whites Goldmaster GMT and blowing by the coins and just cherry picking jewelry. Far fetched?
Best regards,
Steve & Family.

I agree with Monte. My modified IDX Pros set up properly using the expanded disc. of the black sand feature and using minimum discrimination will hit small gold as well or better than a lot of higher frequency coin and jewelry detectors. For small gold chains in the ground watch for a iron to foil bounce on the meter with a weak soft signal.

As Monte pointed out, for coins you need a little more discrimination and the Whites GMT isn't the best choice in that regard. Although for micro jewelry like fine gold chains etc, the iron ID on the GMT is quite accurate. Anymore discrimination and you will loose micro gold.It's best to dig all. The Gmt will pick up the reflector silver paint chips from the back of junk gems. Fine gold chains air test @ 4" (no clasps), and dry wood chips similar depths. 12" on a fine ladies 18k diamond ring, which is more than enough for the shallow bed of wood chips.
You must have patients for this level of micro resolution style hunting, as you will have to dig tons of itty bitty foil hits. You might be rewarded with a diamond stud earring for your efforts.
Sure makes for good nugget hunting practice for later in the gold fields anyway.
It's fun.

Not a bad idea. You just need ferrous/non-ferrous discrimination in tot lots. Adjustable iron disc would be a plus as you could dump the nails but still get the bobby pin range targets. Would hit decent on chains and remmants of chains. Would also drive you a bit batty if someone spilled some BBs 
You'd need to hunt as if you were prospecting to recover some of the tiny targets you'd hit on. Need a good handheld electronic pinpointer. In sand a plastic measuring cup will be useful for recovering those BBs.
I've done the same with a Fisher GoldStrike in the past and plan on doing it again in the future. Be supprised at all the little silver and gold pieces hiding in those places. Be supprised as well at how hard they are to recover.
