Hi guys.....I have a depth question for you.....>

I just purchased a MXT to back up my DFX....I was wondering about the depth of the MXT. What was the deepest coin you have dug with it?? What settings do you normally use. I noticed the MXT is a bit more sensitive than the DFX. Thanks for any help fellas.

Matty, using the 950 coil, in teh CJ or relic mode, start with a gain of +3, and see if your soil is mild enough to use that high a gain and still retain stability. If not, progressively lower the gain, until stable operation is restored. With the 950 coil, I'd guess that you CAN use a "+" gain. I am fairly certain you can run it "wide open" with your 6x4. You should be able to dimes to 7 inches (maybe more) with the 6x4, and 9 to 10 inches with the 950. This is with the CJ mode; with the relic mode, maybe even deeper. Yes, you will find that the MXT finds smaller targets more readily then the DFX; it was designed to do so. Now that you have the MXT, get ready to find deeper stuff, like more colonial coppers, and Spanish silver. <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt=":)"> HH Jim
 
I can probably best respond to your depth question with the very ambiguous reply of "it depends." For example, in my area of southern California, ground mineralization is pretty consistently high, which means that I would have to keep the gain at about 9 with the stock coil to prevent falsing. With this setup, I was regularly hitting coins in the 4-6 inch range and occasionally getting them down to 7 or 8 inches. Deepest was, I believe, 10 inches. With less ground mineralization, you can crank up the gain and effectively increase the depth of the machine. For instance, I recently switched to the 10x6 DD coil, which helps with the ground minerals. I can put the gain at +1-+2 and am regularly hitting targets at 6-8 inches, and sometimes pick up weak targets at 10 inches or more, depending on size of the target, etc. So trying out other coils can be helpful with regard to depth. You can also play with locking the ground balance if mineralization is high--this seemed to help with depth and VDI readings on deeper items.

I got a good signal and dug and dug and dug. when the hole was about 8 inches, I totally, completely lost the signal nothing zilch. I knew the target was in there so I kept digging the bottom of the hole a little at a time til I got the sigal back and finally found the 1916 wheat Penny in the very bottom of the hole. I measured the hole (first time I'd really taken a measurment ) and it was 9 inches. And I positive the coin came out of the bottom because I watched it. I was running gain on +3, very little discrimination and in relic mode (well actually I usually us both Relic and C/J switching back and forth on a target.
 
First, just a reminder that total detection depth is almost always going to be greater than what you can actually get a reliable TID reading on.
I watched a gal swing an MXT and get a decent 'hit' on an 8
 
Having read your post awhile back about using the MXT in the locked position, I tried it and like it much better myself. The only time I use the MXT in trac is on wet salt sand.
But how do you set it slightly positive? I have been setting mine by the site, pumping the coil till the unit stabilizes and "sets in" on a particular number, and then locking it.
Could you explain please?
Thank you,
Neil
 
I dug a flying eagle cent at p" with my DFX so I 100% believe you. Thanks for the post.

and I hunt with it locked about 90+% of the time. As you know, I posted about the "preset" '83', if you turn it on in the 'Locked' position, and for most sites this is going to be a positive ground balance. If the site has a phase reading of perhaps 77 or 79 then the 83 is positive.
If I chance upon a site that has more mineralization than where the Lock setting is, and that can happen a lot around here with our bad ground, then I toggle to Prospecting mode and go into the Ground tracking mode. If most of the ground reads from 81 to 85, for example, then I will lock it at 85, making it slightly positive over the 81 ground. Simple to do.
I do not like a radically positive setting, just one that is slightly positive.

Thanks Monte. That sounds close to what Im doing now.
Ever since your first post about locking in the MXT Ive had deeper and more frequent good finds.
Hope your having a great summer,
Neil
