I was looking for a really "SHARP" knife like seperation of targets like you explained in your threads ..... Either your coil is different than mine, or it runs differently on a GT than it does the original Soverign , but I get good seperation , but not knife like ..... I would say that it seperates about the same as my S-5 ,but no better .....STILL a great coil ...It runs a LOT more quiet than the stock coil , and I think it may go a bit deeper ....I need to spend more time with it ..... I think that it ID's a lot better than the stock coil too .......
In response to this remark in another thread from Synthnut about the 12x10...
The sharpest portion of the 12x10 and the 15x12 is the last 3 or 4" of coil near the tip or tail. Separation in the middle of the coil doesn't really seem quite as good due to the hot concentric (or at least it feels that way) middle to it, but still feels better than a conventional DD to me. I only use the middle of the coil for of course general searching, but once I find something to check out I'll back up and use the last 3 or 4" of the tip to check it out. For really tight targets near each other I sniff things out with the very tip of the SEF. That's where it feels razor sharp (the last 3 or 4", but even sharper as you get closer to the tip). Thus far I've only found a few super deep targets that the tip of the coil didn't see quite as well as dead center did, so keep that in mind if you sweep over a real deep one with the tip and the thing seems to null like iron. Get dead center over it and make sure it's not that the center is just seeing it better. Really I can't say that the center has saw targets better at fringe depth for me than I could with the last 3 or 4" of the coil, but just the same I'm always cautious about that just in case. I was never one to use the center of a DD coil for pinpointing or checking out targets. I always back up and use the front portion of the coil most of the time to check things out.
All that being said, I feel the 12x10 at least separates better dead center than the 10" Tornado (which is a real good coil at that), but things get real precise if you check things out with say the last 3 or 4" at the tip of the SEF. I've hit many coins with the tip that dead center would just null over due to nearby trash, yet I could isolate and get a great coin signal from any direction sniffing around with the tip. I just try to remember that- Perhaps slightly more depth dead center (though I doubt it) and with real good separation, but for sure more laser like target separation using the front or back 3 or 4" of the coil.
The only slight drawback which *might* be true of the 12x10 to me so far (every other aspect of this coil has been a huge improvement to me over the stock 10" Tornado) is it *seems* like I have a little less ability to tell oddly shaped small trash targets like bits of aluminum from something round in shape. The audio seems to have a little less telling traits at these types of targets than the 15x12 or the 10" Tornado. Now, I'm not sure if that's the case yet because I'm still learning the language of this coil. And, it for sure hits harder on tiny bits of stuff like aluminum, so that might be why I'm getting fooled a bit more and has nothing to do with any less ability to provide those audio details. It could also just be that I'm not used to the higher pitch targets put out and haven't tuned my ears for that properly yet, so I'm still learning how to speak it's language.
One thing for sure is that it seems to peek my interest more on real deep coins with it's slightly higher pitch than the stock coil, so I would gladly trade off a little tiny target audio ability in terms of what it is if it means I'm getting deeper on coins with this coil (which it appears to be doing thus far but with more testing to do). If anything, for sure you need to learn how this coil speaks. It is not the same as the stock coil and somewhat more different to it than the 15x12 was. To me the stock coil and the 15x12 have a more deep/rich sound to targets, while the 12x10 has a crisper, sharper, more focused report on what it's seeing.
It might be that for some reason my hearing with this coil isn't quite as good on tiny trash items versus good round ones (this is just a vague impression so far), and if that's the case then one might want to use the 15x12 or stock 10" coil for gold ring hunting if they are the type who really has built up a skill to hear gold rings versus trash. I'm not saying the 12x10 lacks this ability, but I am saying that I'm still learning it's language in that respect. Like I said, it might just be that this coil for sure hits harder ton tiny bits of stuff, and so I'm thus digging more bits of junk that sound half way decent where as the other coils don't have as good of ability on them and never produce a strong enough signal to bother with.
