Sovereign GT 15 x 12 SEF Coil

Not as deep for me in my mineralized soil as the stock 10" Tornado on coin sized targets, but it did get deeper in my mineralized sands for some reason. I enjoyed it's stability and coverage for large open areas to grid even a bit faster than the improvement the 12x10 gives over stock in the respect, but I feel keeping both in my line up is like having two somewhat identical cars in my driveway. For me the 12x10 is deeper on both land and sand than both stock and the 15x12 and separates better than both, although both the Tornado and the 15x12 are no slouch at left/right separation either.
The 13" Ultimate is so unlike other coils, including the SEFs, that having been loaned one to try I plan to add one to my line up, since I won't feel like I'm replicating the 12x10 by having it in my arsenal. Very different coils. And even though the SEFs are obviously very different from "conventional" round DD coils, the Ultimate is very different from other conventional DDs even though it's round. It's kind of weird that it looks somewhat in certain ways like a Pro Coil, don't it? Might be something behind that...

Hey Frank, as you prob know Critterhunter knows a ton about the Sov and coils. His posts have been helpful to me. I have the 15 x 12 on.my GT and have a good number of hours with it on the beaches. It goes very deep but I'm learning that in some cases I was running my sense too high - some signals were degrading that I should be digging. Took some experimenting to discover that. I'm learning a couple of methods for setting the sens - see some of the posts here re that. If you want to try my 15x12 SEF we should get together soon. I can run the WOT on mine while you try the 15x10, and see how ya like it. It's got some heft where there 12x10 is lighter. Another week to 10 days before I'm cleared by the doctor. The only places left to hunt will be the shoreline after today's 2 feet of impending snow. I'm going nuts to get out and back swinging.
Talk to ya soon.

If you ditch the coil cover and use spray on bed liner the 15x12 is even lighter than the 10" Tornado I think from memory (check the coil weight thread in the coil sticky).
I too found that a lower sensitivity with it often gave better ID and tone at depth, much lower than max stable sensitivity. Only coil I've seen that with thus far, and I think it's due to it taking in too much ground matrix for it's size. Only way to tell is to find a fringe depth whisper at max stable sensitivity and then start lowering it at you sweep over the target. Often I found say while a 9PM sensitivity setting was stable, around 1 or 2 PM seemed to give me a much more easier/clean ID and tone at depth.
I should make a clarification- I said the 12x10 was deeper on both sand and soil for me than the 15x12 on coin/ring sized targets. Not sure if the 12x10 is any deeper in my sand, but for sure on land it was deeper on such targets than my 15x12. Both my soils and sands are mineralized, so the only thing I can guess is the types of minerals at my land sites was too much with the 15x12's size to for the Sovereign to deal with when ran as hot as possible. The official field report of these coils though does show the 12x10 is deeper on dime or at least sub-dime sized targets than the 15x12, while the 15x12 was deeper on say 50 cent sized targets or bigger, as one would expect with a larger coil.
The 15x12 is a great coil for sure, and for it's size is no slouch at left/right unmasking. I dug a barber dime in the midst of some heavy iron with it, along with a merc in the midst of some heavy tabs and foil, that were surrounding by all these things. If a target interests you, try wiggling the last 2 or 3" of the tip at it. Both SEFs get even more laser like in the DD line near the ends, although the center is even more scapel sharp like than any coil I ever used.
The 15x12, like the 12x10, are rock solid stable coils in both EMI and heavy iron. They seem to ride over such pot holes in the road without getting themselves bounced out of control. Faster "recovery" from such distractions is key to finding masked stuff. Both outstanding coils, and one day, even though I plan to pick up a 13" Ultimate as my big open area coil, I plan to pick up another 15x12 again for such areas, but 99% of the time the 12x10 is my go-to coil for land hunts.
If anybody is considering using the SEFs in the water, don't get one for that unless you can deal with a good bit more drag than the 10" Tornado. For that reason, I may pick up a S-12 just for my water rig, as it's round shape might not be any more drag than the Tornado for the most part.
