Same depth MXT - MXT Pro w/ concentric & dd coils

[Aarong81]

My experience with 7 tone has been helpful. I hate to stare at a moving screen while I detect. Information overload is relevant. First, I don't descriminate much, everything over +10 or so is audible. I do NOT dig everything over +10, though. The reason to use a low disc is to avoid nulling out or masking a good target with junk next to it. That being the case, even if I used 2 tone I would hear all the same targets as when using 7 tone. However, if I'm swinging away and hear low/mid tones I keep swinging. If along the way I hear a mid/high tone I know to focus on it better to decide whether or not to dig. By mid/high tone I mean +50 and higher. When it gets to +60 it will stop you in your tracks. All those countless +10,+20, +30 targets would have me stopping to stare at a screen every 3 seconds if it were not for multi-tones. When you get used to the tones you don't have to look at the VDIs. The same amount of information is available, and needed, whether you stare at the screen to register the VDI with your eyes or if you are told the ID(tone) while you listen. You can easily confirm the exact VDI but the only time I want perfect VDIs in order to dig something is when I dig nickel signals. Even then, the VDI might be off 1 or 2 from what you think it should be.
Keep in mind, certain areas call for digging everything over +10 or even lower for some people. My style of detecting is to dig +50 and up unless I am in a low trash area, virgin ground, ect. One can only stand so much tin foil and pull tabs. Most of the signals I hear are 'dont dig' signals and the 'dig signal' stands out. I still want to know what is there, whether its a low/mid or high VDI. With 2 tones you only know whether it is below or above a set VDI and you will then have to obtain the same information overload to make a decision about digging.

I think I'm going to miss my analog VDI meter! I'm not sure if this is just one of my little quirks or if a lot of people have similar experience, but my brain processes visual info way better, smoother, faster etc. than auditory info. For instance if people want me to understand their instructions it works way better if they're written down than spoken. Also, visual info in graphical form - way better than in text form. Its like there is an extra translating step for my brain to perform when the data is in text form but when I see that needle move it instantly conveys so much understanding - anybody get my meaning? Does anybody else have experience with the old analog VDI meters? - does anybody want to admit to being that old? Yes, there were machines before that, that had no VDI at all, granted, but there is just something about watching how that needle moves - not just where it stops, but what it does along the way. Also, I generally keep track of the VDI meter in my peripheral vision without really focusing my full attention on it - if the audio registered a solid hit, only then would I study it closely. I'd be willing to try the 7-tone thing, Aaron, based on your recommendation, but I think its going to take a substantial retraining of the grey matter to really make it work for me.

In mild ground the concentric should be deeper.... BUT.... at depth, your search area is very small and you should overlap maybe every 2-3 inches to get good coverage. The DD gives up some depth in mild ground but better coverage at depth.

The diagram on left is concentric (conical) the two on the right is the DD coverage from front/back and from the sides.

Those Pictures have been banded all over the web and they are Totally Incorrect, you can easily prove this to your self by laying down your machine and turning it on and waving A Test piece by the side of the coil or just walking past the Coil in your work boots,

Pictures like that were used to sell Detectors from companies like ML and a few Others, The only correct picture there is the Side View of the DD, There is no way A Concentric puts out a Cone shape like that, It's more like a rounded version of the side view of that DD,

Jeez sweeper don't get your panties all in a twist, those are simplistic drawings to get the general idea across to the general public, not actual search patterns. Search patterns from each coil could vary greatly from the drawings depending on mineralization, coil design and many other factors.

panties, PANTIES,, What Panties I'm Wearing A Fig Leaf,, I can't wait for Autumn / Fall l


Seriously, even though we know they pick up from such A Large area around the Coil, I have used the 12/300 coil In junk sites just to see how it fared and it seemed to do quite well, Too Well In Most Cases, But I just Bought Another MXT ( All Pro ) and Dare I Say it,, this Set up With the D2 Coil Seems to be The Hottest Combo So Far, It Seems Hyper Sensitive And Extremely Powerful compared to the 2 previous Models, So whether Whites has Been Doing what they Do Best I don't Know,
I have Had Them All and all the Coils to Match But I have found the Concentrics to be Hotter On Tiny stuff, But On this New All Pro The D2 seems like it's On Fire, I would always go for the concentric But Seeing as Whites have not said whether they have Boosted the MXT's Power or Hot Rodded the D2 Coil, I am now having to re-think The Coil / Sensitivity Issue.

On the GMT Concentrics are The Winner,, But with the MXT's We Have to Go Back To School Because it Appears That with DD Type Coils things Are Changing we are going to see some good things happen,

Take Care Larry,

So after reading all the post. I think it's safe to say my vintage 2007 MXT is not worth upgrading to a "PRO"?
Not unless I need a back light or tones? Which I really don't. I run relic mode 95% of the time. Even coin shooting.

Since my earlier posts I've had a chance to puts some hours on the "Pro" in 7-tone and I actually like it - didn't think I would. I take advantage of the trick - a software bug really - where you set it to 7-tone in C&J then click the toggle into the "relic" position. The high tone is really great for cherry picking good targets from trashy areas. Also, I used the back-light for the first time yesterday when I brought the machine under the front porch for a little hunt - came in handy!
