Does anyone here have experience hunting ground reading in the low to high 70's

Hey Jason, I have but I use a Whites 6"x9" Eclipse Coil, and I don't have any problems. If I'm not mistaken, I read several months ago. That any ground readings from 70 on up, are considered relatively hot ground, and will effect your hunting efficiency with the standard concentric coils. Either Jim McCullough, Art(S.C), or Rick(N.D.) are far more qualified, than I am to evaluate your question. I'm sure they will respond to your question either today or tomorrow,
unless they are unavailable. They give some thorough and great advice. Good luck, hh, lol.

aAl the ground i hunt up here is in the mid 70's(74) and most of the time i turn my gain down just a hair below the preset and run my disc. at 9 oclock. With the stock 950 coil.I dont think i lose to much depth. but hey maybe i need to learn this too cuz i ain't found any pre 1900's coins yet <img src="/metal/html/grin.gif" border=0 width=15 height=15 alt=":grin"> .

Hi Jason,
Glad to see you are out using that MXT.
I've hunted ground far hotter than you've described, and with worse hot rocks. Hot rocks by and large are not something you discriminate out, they are something you learn to identify. The only units that by and large ignore hotrocks are the are pulse induction (PI) detectors, and they are of limited use for coin detecting.
First step is to back off on your Gain. The hot rocks you are describing are the granite/diorite rocks from the Talkeetna Mountains that the glaciers carried down to your area. Bury one of these rocks and a dime and set the Gain to where the dime hits best and the rock is weakest. You will lose some max depth this way, but it is how you deal with bad ground/hot rocks.
If you go to the prospect mode the disc control becomes a VSAT control, and the proper adjustment of this control will also help smooth hot rocks. You still get VDI number for target id. Most people find this mode too noisy, however, for coin detecting.
I would not recommend locking the ground balance but using it in auto. Both the dime and a hot rock will signal on an initial sweep. But with auto ground balance on the rock will fade as you zero in on it, while the dime will still sound strong. Balancing to the hot rock and locking simply puts you way out of tune for the normal ground, not a good thing. it is sometimes possible to find in-between balance settings that work, but this is very hard to do on a machine without manual ground balance.
It really all boils down to time and listening. Most hot rocks do not "sound right". I really like my MXT but I have little use for VDI meters. I set my unit for minimal discrimination and dig things that "sound good". If I watch the meter it just messes with my head.
Any normal lower frequency coin detector will ignore the rocks you are dealing with. Since chasing nuggets was one of your prime desires, you got a good machine in the MXT. But its higher frequency and extra sensitivity translate into more noise. When starting out, my best and simplest advise is to just turn down that Gain control until the machine gets quiet enough to not wrack your nerves.
I had good luck with the MXT and 10"x5" DD coil in the Fortymile area, where the ground is hot and the hot rocks worse. I'm not saying the machine was quiet... not at all. But it helped alleviate the issues and found me nuggets. But overall my favorite coil is the little 6" DD Shooter coil. Good for small gold nuggets and real fun for coin detecting trashy areas. It spends more time on my MXT than the stock coil.
Give me a call sometime. maybe we can hook up this spring with a few other MXT owners for a day at Crow Creek.
Happy Hunting!

Hey Jason, in response to using the 6"x9" Eclipse Coil, I have only used mine about 3 times, because I can't get out to hunt as often as I would like.
But, I haven't found it to be tricky or anything.
I think I read previously, that the depth readings may be off an inch or two, but I'm sure one of the guys I mentioned in the earlier post, will advise you, when they see these posts. LOL/HH.

Hey Steve, nice to hear from you.
The MXT didnt stay in the box much longer than it took to pay for it and carry it out the door.
Recognizing the Hot rocks has definitely been my biggest challenge. Great tip about burying the dime with the Hot Rock. That will be a huge help. I need to school myself a little more as far as recognizing the sounds different metals make. I have had some of my targets fade out upon targeting and didnt realize why. Will other metals do this also? It sounds like I need to order a 6 inch coil. I did buy this machine for prospecting and I need to get in some practice. A crow creek trip sounds fun. I would enjoy meeting all the other MXT owners in the area, and would definitely benefit from all of that knowledge "Might find a big nugget too <img src="/metal/html/super.gif" border=0 width=26 height=28 alt=":super"> ". I will keep in touch. Thanks for the help. HH

With your advice for the 6x9 and Steves for the 6" I know I am definitely going for a smaller coil.

A few dirty bad nasty parks with subsurface bedrock are in the 78-81 range.
I haven't had problems, for the most part, with the MXT's I owned, with 'Hot Rocks'. I often use a smaller-than-stock coil, and that helps. I also do NOT rely on tracking in the more challenging environments, preferring to have a somewhat positive GB. MXT, XLT or XL Pro, I prefer to NOT use autotracking most of the time.
Just me, perhaps.

Hi Monte,
I agree... I usually do not use autotracking myself. But if hot rocks are an issue it is worth playing with. It will often quickly track out some types of hot rocks while still getting good targets. As always, small or deep targets may also fade, but in some hot rock situations that may be an acceptable trade.
What method do you use to get a locked and slightly positive ground balance setting on the MXT?

I have found the autotrack circuitry can work too fast in many environment, especially with a lot of varying types of rock, decomposed iron and tin, to name two, for me to enjoy it. It causes too much 'noise' in the circuitry with frequent updating.

Also, yes, there are times when it <EM>might</EM> be good to have some autotracking taking place is rock mineral conditions are radical, and especially with smaller rock specimens.

Great post with great info. I too hunt in the mid to high 70's and your post helped me alot. Especially learning the pre sets......I never knew that.
Truly a great forum with great folks!
thanks again and HH

I have shown that to dealers and one or two others who I thought would have known about it.
I worked some street & sidewalk renovation last Veterans Day over in Washington. Most of the sidewalk already had a thin layer of rock leveled to ready it for pouring. My friends had a terrible time trying to establish a workable GB, and the autotracking kept giving them fits!
Me? Just set it in 'Lock' and turned it on with an 83 GB level and hunted away w/o a problem. Popped late 1800's 'V' nickels and Indian Heads while they were trying to get stabile.
Glad I was of some help to somebody.

This is great info. Thanks again.
My serious question for you is, How the heck did you find this? Did you stumble on it yourself or did you come across it someplace? I cannot comprehend how this kind of info is discovered.
I assume that even though White's does not make this public info it was designed into the system for some reason. Any insight in this area?
This is like finding an easter egg in computer software.

first checking out the MXT. I have owned two MXT's and even before I bought the first one I wanted to learn as much as possible, so I used some loaners from dealer friends. Been doing that anytime I get any detector in my hand, and I am on my 40th year of detecting.
It isn't anything I ever saw in print or heard from anyone. As a matter of fact, this 'default' start-up phase reading/setting is something that I have usually only told to friends when doing some hands-on help, or in some quiet E-mails, or in my seminars.
For all these years I have always wanted to make the #1 thing I did whenever I turned a detector on was to either learn something new, or refresh my memory/knowledge about something I have learned in the past. Achieving #1 helps me enjoy reaching #2, and that is to find something of interest.
Questions? Feel welcome to drop me an E-mail.
