GMT Question

[RELIC_HUNTER]

Times $$$ are getting hard and I have the chance to buy a GMT for $300. I am not a gold hunter,but a civil war relic hunter. How would this machine do in this type of hunting.

I think you answered your own question. If your not a gold hunter then use the $300 to buy like an IDX. The GMT wouldn't go too deep being 48 kHz compared to a lower frequency unit. You wouldn't cover much ground swinging the GMT slow. You'll be better off buying the right tool for the job. But $300 is a great price. You might be able to make some money on that deal and buy a 6t, M6 or MXT?

VERY good info khouse.

IF I heard right, "The MXT is a two filter detector and is designed to hunt slow, comparitively speaking. If you want a fast White's go with the XLPro (four filter) or set up an XLT or DFX accordingly."

Are the 6000 DI PRO, IDX, 6T, M6, fast mahines or slower like the MXT??

Are some Whites units faster hunters than others??

Why you might say, because if a person is a Relic Hunter or (homestead hunter) there are very large fields to cover and a slow sweeping unit would take 2 or 3 times longer to cover ground and time is valuable.

YES higher frequencies have less depth BUT are they are more sensitive to iron relics(being lower conductive), than a lower frequency or not noticeable?

YES higher frequencies have less depth BUT are they are more sensitive to iron relics(and gold, both being lower conductive), than a lower frequency or not noticeable on larger iron relics? My opinion on this is, Minelab use to have a dedicated gold machine called a GT and FT 16000 at 5 kHz and Garrett had the ADS Deepseeker at 5 kHz for gold. I found about small 1 gram nuggets with the GT, so low frequency units will work fine on small iron relics and gold but just not on the real small pin-head micro iron and gold where higher frequencies are better like on the GMT. So it IS better to have a low frequency for hunting relics as it will pick up your valuable iron, brass, and lead mini ball relics just fine and you will go deeper like khouse said.

Go to the Whites web site. Go to videos. Fire up the GMT videos. Go to video #2. Watch Jimmy Sierra work the GMT. I personally haven't used the GMT but have watched the video set twice in the past. I know Jimmy helped design the GMT and knows how to use it. Typically lower frequencies go deeper and hit high conductors better. Also a lot of relic hunters don't mess with small iron. But do use iron signals as an indicator that activity has been on a site. If I were to go prospecting for gold (dreaming here) I would strongly consider the GMT for the info rendered and price point. It looks like a lot of detector for the price.

And they are so sensitive to such small targets it can really keep the ears very busy.

That's a good question and based from air and back yard testing one would think the GMT would be a great relic detector, I recently picked up a GMT & MXT and after a series of (square nail-coin) test the GMT prospecting mode appeared to see though the iron petty good and detect the coin.

But out in the field it's a different story and I was getting fooled with the GMT by iron signals allot more than I would have been if using the MXT in relic mode, The GMT is good for prospecting and for tot lots eliminating most iron signals using the (iron Grunt audio) and (percentage iron target) features but for serious relic detecting go with an MXT.
