White's MXT Question.

[cwilk]

Hi guys! I am a regular poster over on the Garrett forum and have a question for you. Tonight I met a fellow detectorist who was swinging an MXT and we naturally got to chatting about our machines and he told me that his MXT could routinely find ID silver coins at 12-14 inches. I think he was using the stock coil. Since the site we were mutually hunting did not produce any silver for either of us we couldn't test his theory. I asked two or three times if he found silver coins in discriminate mode at 12-14 inches and he said yes. I asked again, in discriminate mode and he said yes. I was a bit leery and figured I would ask here. FYI my Garrett GTI 2500 will find and ID silver coins accurately down to about 8 inches if detecting conditions are perfect. Deeper than that the signal can be anything, iron, silver, alumininum, clad..............

What I would like to know is how deep the MXT would regularly find and ID a silver dime in normal, moist, soil, in say an old school yard.

I am not trolling or trying to start a brand vs. brand discussion. If my new friend is reading this I'm sorry I didn't see you leave I wanted to get your phone number. It was nice meeting you!

The pinpoint stops at 12 inches, but the VDI is on the edge at 10 inches. I'm afraid its much like your Garret in that if an MXT user gets a deep signal (over 8 inches) he would be wise to check it out, especially if he's getting a mixed sound, with a hint of high in it. If your friends unit IDs at 12-14 inches he has the hottest MXT I've ever heard of.

I want an MXT like your friends. Mine won't go that deep in "perfect" conditions. Yes, I have retrieved solid signals of silver, targets, misc. at 8 inches and some beyond, but usually it stops there. Sometimes I do find that old Studebaker DEEP. But I usually leave it buried. I would hate to have to use a back-hoe in a yard. I think your new friend was pulling your leg. Maybe both of them. HH to all, Nancy

Not a chance. I have pulled silver at 10" but rare and no VDI. Just a rise in threshold so I was just lucky when I dug it up. The VDI numbers will start to fall off after 6 inches and after 8 inches you have to dig everything if you want to know what it is which is no big deal because most of us dig anything that deep anyway,

Maybe it kept falling to the bottom of the hole until it was at that depth when he finally saw it.

The exact answers I was expecting. I know the detector is a good one and I know mine is as well. When I heard he was getting almost twice the depth I was getting I expected it was a little exaggeration and maybe a little inexperience. I think this guy may be sort of new because he was reburying his junk and digging some pretty large holes for some pretty shallow coins. I should have said something but didn't. He had found some real nice old coins at a few choice spots!

I have found a few very deep silver coins at around a foot with my GTI 2500 in true all metal mode which sounds like what one of you guys called a change in threshold. Those few coins required digging maybe a hundred pounds of garbage. I don't dig much deeper than 8-10 inches now.

Good hunting and if your in Texas please find some place safe and dry this weekend.

I have used the MXT in various areas, some with really good ground, others with really bad ground. In really good ground, optimally tuned, dimes can give a faint, but repeatable signal, to 10 MEASURED inches. In bad ground, such as we have here in the Mojave Desert, the depth drops to about 8 inches, MEASURED. The VDI depth is about 70% of the audio depth, thus, as I've often mentioned, be sure to dig faint, repeatable signals which DON'T give a VDI lock on. The reason I mention MEASURED depth, and perhaps the reason why the guy you met offer such optimistic depths, is that many folks don't have a clue how deep a coin really is. For example, at a detector rally I will dig a 3" wide hole, exactly 4" depp (MEASURED) and then ask detectorists to "eyeball" the depth, and tell me how deep it is. Probably 90% answer "six or eight inches." Really. Thus, to such folks, a dime REALLY 8" deep looks to them to be 12 to 16 inches deep. Thus, these "super depth" claims are often unknowingly exxagerated. HH Jim

I've pulled mini balls at 8"-10" pretty routinely with my MXT, perhaps some even deeper. This was from sandy Georgia clay/dirt. I've hit on the rifle percussion caps at about 6"-8". These minis' are much different from a coin, but a dime at 10" seems a stretch.
