I'm curious does anybody know? what's the difference? what make a deepscan coil that as opposed to a regular coil.

What is difference between a regular 950 coil & a 950 Deepscan coil anybody?

The 950 coil is a concentric coil and modern coils that are labled "wide scan" are a DD or SEF style. I think the older deep scan 950 is just a name change on the same coil, I might be wrong on that......it has been quite a few years..............
This is "in part" of a post I just made on the XLT forum concerning the concentric vs. the modern "deep scan" type coils.
So much depends on the ground to determine if a DD or concentric coil works best. In my ground a concentric simply can not get the depth that a DD or SEF style coil can. I did a lot of the initial coil testing on the prototypes of the V3 and the D2 coils. Hundreds of hours went into comparing concentric, DD and SEF coils in the development of the D2 and which coil might be the best coil to issue as the "stock" coil on the V3. The DD style D2 and SEF coils won hands down in my testing. For almost every major manufacture to issue a "non-concentric" coil as stock may suggest that it is more than just a passing fad. I long used the 10" DD Excelerator coil as my "stock" coil on the DFX for many years, clearly getting more depth and quieter operation with the ground noise as well.
With the electronics technology hitting a brick wall on gaining more depth in the ground, the development of newer and better search coils is what is going to get us to new depths.
What coil works best for you is still a personal choice and that is why there are so many choices of coils for the average user.

A 950 would "scan more deeply" than an 8" or other smaller-sized "stock" coil that was common with most brands at the time.
Back 35-40 years ago, a "Double-D" or "DD" term was used to describe the physical appearance of the internal Tx and Rx windings of a "Wide-Scan" coil and Wide-Scan was a popular term to describe them compared to a few other configurations in use at the time. Through the years since, there have been some manufacturers who favored the term Wide-Scan (such as Tesoro) while others opted for the term Double-D. They are both the same thing.
Wide-Scan suggests a Double-D design. Deep-Scan simply is used to market a deeper-seeking coil for, perhaps, larger-sized targets. It shouldn't be confused with a Wide-Scan design. All the 950's have been essentially the same coil.

So what your saying then the coil on my QXT that says 950 deepscan is say no better than my 950 coil on my spectrum XLT ?

Hey srf2112 you got a Quantum? what model 
I picked up a QXT pro with the stock Black Max 950 coil on it a couple months ago. It is one of critterhunters old machines. Being so new to MD'ing ( 5-6 mo's ) I was a bit confused and frustrated at first but recently took it out with more knowledge and experience under my belt and man am I impressed. After starting to get used to the tones I'm really seeing why so many hunters love the multi-tone feature on their machines. I almost sold it but am VERY glad I didn't. It will be a long time until I can maximize it's effectiveness but learning means hunting and that's ALWAYS good. I had also been having trouble getting comfortable with the relic mode on my MXT but after a little time on the QXT everything is falling into place and the relic mode will be getting a lot of use when I'm healed and can start hunting again. Sorry, I know that's a lot more than you asked but once I get started talking about detecting......
