Tried the new d2 on the mxt pro . Experimented with it to see how well it separated signals.Laid my wedding band on top of a rusty knife blade.It read the ring loud and clear and ignored the blade.I covered the ring with the blade and it picked up the blade only.I turned 90 degrees swept again and it picked up the ring.Partially covered it was a mixed signal which ,as a relic hunter, I would have dug. If it was buried it may have responded differently. Looking forward to see how it works.How does it compare to the 6x8 sef?

MXT PRO w/ 10" d2 coil.
- Thread starter stonewal
- Start date
I'll share my thoughts. I really like the MXT Pro. It was an excellent performer for me in the sites I hunted, especially with my favorite two search coils
I really do not care for any of the 10" D2 DD coils I have had. Even the few that kind of worked okay, so it wasn't one of my two favorites.
What types of sites do you generally hunt?
What is/are the reason/s you had for getting the 10" D2 DD coil?
I can guarantee you the detector didn't "ignore" the blade unless it was rejected. Even then it still didn't "ignore" it, it only rejected or Discriminated it [size=small](if so adjusted)[/size] and the EMF still was affected by the blade, but the audio circuitry rejected it so you didn't hear the response.
Okay, so which direction did you sweep the coil over the knife blade the first time? Lengthwise or crosswise? That would then give an idea of the direction-of-sweep once you turned 90°, but my guess was the first time you might have swept lengthwise, and have now turned to sweep across it in a narrower position.
I am also going to presume that you are using a knife with a steel blade and not one of a non-ferrous material. I watched a fellow once work and work and work to try and reject a knife blade to try a similar stunt, but couldn't. The knife blade he used was made out of 'coin silver' so it was over 80% silver and quite conductive.
Using an elongated object, such as a piece of wire, nail, or even an iron type knife blade, and positioning a good target, such as a coin or ring, close to the center or end or on top of or just under such an object, will usually produce a mix of results with almost all detectors and different coil types based upon the targets sizes and shapes, orientation of the two targets, the settings used, and naturally the direction of the search coil sweep. Let's not forget the specific detector as well as coil sizes and types used.
I never really use a Target ID icon reference, and only glance at a VDI numeric read-out, if the detector offers that, just to get an idea of what I will be recovering. Good or bad, if it beeps [size=small](iffy or solid)[/size] then I recover it.
That said, I would easily opt to get the 6X8 Double-D SEF coil if I was going to use a DD on an MXT Pro. I would never use the 10" D2 DD as I have experienced too many failures with that coil along with poor performance in trashier sites.
The 6X8 is a little smaller than the round 10" DD so it should have a little advantage in a trashy, relic hunting environment.
I have two favorite coil choices for the MXT Pro:
• White's 6½" Concentric [size=small](they call a 5.3 Eclipse)[/size] for the bulk of my hunting where there is more trash, brush or building rubble.
• White's 9" 'spider' Concentric coil for areas with fewer targets to encounter and when I want to get a little improved depth in favorable conditions.
Just my opinions, but we all need to use what we have, what we are interested in, and make our own conclusions as to what detector or coil seems to work the best for us in the variety of hunt sites we pick.
I wish you the best on selecting what you want/need, learning what you can, and enjoying success afield.

Curious, which other coils do you have or have you used?stonewal said:

Do you usually search sites with a lot of undesired targets [size=small](aka junk)[/size] that can mask a potential keeper? I have done most of my detecting in such places, ghost towns for over 46 years and urban demo sites and other trashy spots for over 50 years. Target masking can be difficult to deal with, and the best first step I take is to use a smaller-than-stock coil. That way I am not covering too many targets at once in really bad conditions.stonewal said:
Usually a typical happening, depending upon the size and content of the good target [size=small](in this case your ring)[/size] -- the size and alloy content of the undesired target [size=small](in this case your knife)[/size] -- and the settings used. Did you first just reject the knife before placing the ring on the blade?stonewal said:

So back to the earlier question: Did you first reject the knife blade, or were you still responding to the blade, but interpreting the response, possibly, by an audio tone, such as a lower-tone for Iron? How do you determine it picked up the knife blade only?stonewal said:

Let's not forget the specific detector as well as coil sizes and types used.
As a Relic Hunter [size=small](which is mainly an attitude we use in our detector/coil choices, settings, and how we handle different sites)[/size] I search some sites in an All Metal mode or with an All Metal Accept Discriminate setting and recover all targets. If I know I am dealing with a trashier site and want to ignore some problem ferrous trash, especially iron nails, I will use no more than barely enough Discrimination to just slightly reject Iron nails. Even if they are just 'ticky' that's fine. Then I rely on the easy, simple, long-held approach to success ... "Beep-DIG!"stonewal said:

I prefer Concentric coils on most detectors most of the time, but there are exceptions. DD coils, as a rule, do not Discriminate as cleanly as a Concentric coil, the Target ID responses can often be more radical and have less 'lock-on' than a Concentric coil, and in many places I don't get quite the depth of detection from DD coils as I do for a comparable size Concentric coil.stonewal said:

I bought the MXT Pro for a backup unit and a general use detector.My main detector for relic hunting is a Tesoro Tejon.In our soil in North Ms. it is a very good unit for me. There is no problem with mineralization here.I run no or very little disc.I bought the 10"d2 because of so many positive reviews.
Been hunting since 1960's used a lot of different detectors.Like they say tho a detector is only as good as the operator I'm an old coot now but I still love it--it's the hunt.Its not so much what I find but I have done well at it. "Even a blind hog will find an acron if he roots long enough" : )

---I'll bet you could teach us ALL a thing or two! 
from your response over on AHRPS. It happens.
Curious, when in the '60s did you get started? I didn't get intro it until I build a metal/mineral locator from a kit in March of '65, and used "home-builds" until my first factory produced in the summer of '68. That was a White's Ghost Towner BFO. Looking back it seems [size=small](if my aged think cap is on straight)[/size] that there has been a time or two when I have changed my mind about parting with a coil or detector and pulled back my offer/ad. Not often, but like I said ... It happens.

I think it was about 1962 with a very cheap Relco all metal. I never saw anyone else for several years with a detector so I learned how and where to look by reading Karl Von Muellers books and they helped me a lot.In fact they are still good for newbies.I know there were some out there looking because of signs they left.After the Relco I got into the Whites-Garretts-Fisher etc. Health is still good take no meds still very busy and I'm tall old and ugly and bruise easy.. : )
After many hours of testing my 2D coil is the hottest Mid Frequency Coil I have ever Tested, Which is Quite A Shock So I phone Whites and Asked them if they have been Hot Rodding their Machines or Coils, As For the Sensitivity It Can See Test Nuggets down to 0.03 to 0.02 grams which is about 0.3 Grains, It will Pick up my Bare hand between 4 to 7 inches, Maybe you guys got one that was not Tuned Right, Stranger things have Happened,
But I think the Machine its self is Very Hot because when I put on my 15" Concentric there is No Loss in Sensitivity and it Can see Test bits smaller than ONE Grain or 0.06 grams, That Really caught me Off Guard and right down to 0.03 grams or 0.04 Grains, What ever has been done Whoops my PI Machine and that's not normal.

really have not given it a fair test--truth be known I use my primary detector when I am relic hunting but I do plan to keep it until I can test it further.Appreciate Monte sharing some of that vast knowledge he has.Would love to hunt with some of you guys and gals out there. Might teach this ole redneck hillbilly some good stuff. : )

G'day Stonewal,
I have been using these MXTs for quite a long while Now And I think they are as good as the Laws of Physics will Allow, A Simple Test, If you lock the Tracking In the Relic Mode with the trigger in the middle position Depending which model you have and Turn the Gain Right up and wave your had in front of the Coil and if it Bleeps at about 1 to 3 inches all is good, Then Try it In The Prospect mode and see how far it will pick up you hand, Depending on your hearing it should pick it up between 4 to 7 inches, If it can do That then you need to use it More Often because you could be loosing Targets, I know Air Test are A Grey Area But they do show what coil is best suited to your machine and the Further they Air Test means the more sensitive they are and if you have Tiny bits of Gold or Lead you can check to see how small targets it can pick up which is good if you want to use A Certain Coil for Prospecting or finding Fine Gold Chains etc,
Good Luck
Monte [size=small](that's me)[/size] is known to frequently post long, long replies. Sometimes, [size=small](and this is one of them)[/size] he [size=small](that's me again)[/size] actually does make them shorter and easily to the point. So, here goes.:
Facts: I very often state that I like 'Simple,' and I like 'Functional,' and I like 'Performance.'
In this case we have two search coils with almost identical internal Tx and Rx windings and, in-the-field comparisons show them to Perform essentially the same.
'Simple' is not really a factor between these two search coils as they both mount and operate in a similar manner.
'Functional' is the primary reason I prefer the newer 9" Spider Concentric coil to the standard 950 Concentric coil. What's is the 'Functional' difference?
Balance!
The 9" spider coil actually measures just a tiny bit more than 9" across. Maybe 9⅛" or so, and the "950" measures more than 9½" inches across. Basically, the spider coil measures a little smaller than ½ in diameter for similar internal windings and field performance.
Next, consider the coil 'ears' where the rod attaches. The rod-mount position is closer to the center with the 9" Spider coil. Not a great deal, but if you measure from the back edge of the coil to the center of the coil bolt hole, I think it was maybe 5% closer. If I had both coils handy, I'd measure them and do the math. I did in a forum post quite a while back but I don't remember the numbers.
Nonetheless, due to the smaller diameter of the 9" coil and the fact the rod-mount point is closer to the center axis of the coil, the result is a better balanced search coil that is less "nose heavy."
I guess an unmentioned reason I prefer the 9" coil is because the 950 donut coil is about a quarter of a century old. Like many people it started out with a slender profile but got thicker/fatter as time progressed, so not only is it rather 'aged' but it got fatter and, to me, a bit ugly and doesn't balance as well. The newer 9" spider is nicely shaped, feels good in the hand, and has more "eye appeal" or I guess you could say it's more 'modern looking' .... or some might even say it is 'sexy looking' alongside the old 950.
Thus, I prefer it for its looks, feel and balance.
