Sun Ray still makes the 12 1\2" coil and there is the wot 15" coil. I was especially interested in the Sun Ray 12 1\2", but since everybody talks about the sef, am I to assume the Sun Ray isn't near as good? Also since I do the beaches I was thinking of the wot, but again, everybody talks about the 15" sef, so am I to assume the wot is a lesser coil? I'm asking because I don't want to buy a coil that isn't going to work well. Inquiring minds want to know.

Why the big fuss about the lack of sef coils?

There seems to be loyalty to certain types of coils, that said, I have heard nothing but GOOD things about the SEF 10x12. The other larger versions seem to be a bit harder to use though. I gave up on trying to get a 5" excelerator and finally bought a new 5" Sun Ray Intruder although I have not used it yet. Now my dilemna is whether to get ultimate or SEF

Both coils work great on the GT about equal, best coil i ever had on my DFX was the SEF12x10 , the S-12 on my GT so far is great i see no fuss swing your coil find a target and dig it, a few extra inches deep better seperation , wiggle your coil ? lol just go out and enjoy the day let the machine do it,s job .

I use both the 10 x 12 and 12 x 15 SEF coils with my GT. I previously owned two S-12's but in head to head comparisons in my test garden, the smaller SEF ran smoother and hit deeper and I sold both Sun Rays. I also got rid of my WOT after trying the 12 x 15 SEF for the same reasons plus it seemed easier to swing for long periods of time. I think it's a few ounces lighter. Different soils and beaches will vary performance of any coil.
One thing to watch with some of these coils is the null factor.Without getting myself in trouble some coils will null on quarters.Fifty cent pieces can null on some coils,so do your homework.I agree with Jim,keep things simple and get out for a search..HH Ron
There is a guy in our club that tried 2 of the 12X10 SEF coils and had this problem you are saying about nulling on quarters. First one had broken up signals on a quarter so it went back and second one just plain nulled on quarters and ask me if it was his Sovereign, but we didn't think so, so he got a S-12 and it worked great with no problems. I never gave it another thought until you mentioned it as I just thought he got 2 bad coils in a row. I had a 8 inch concentric coil that also did this and was sent back for another only to do the same myself and though it was 2 bad coils in a row, but maybe it is more than that and the tolerance may vary more on the windings of the coil on each one and why some like them while others do not.

Thank all of you for your thoughts and opinions. I could really have asked my question in a better way. What I was really wondering was since the sef coils are not made for the Sovereign any more, it doesn't really matter how good they were. Would the Sun Ray 12 1\2 inch or the wot be a good second choice or were there problems with them that I'm not familiar with?

I wanted a SEF 12X10 based on the recommendation of a number of gentlemen on this and other forums. After a phone call to the only USA supplier of this coil I was told that they would not be ordereing any more coils for the Sovereign. I contemplated purchasing one from a supplier in Bulgaria but decided against making an order and then waiting up to two months for the coil to arrive. I then decided to purchase a different coil. Time will tell if I made the right decision.

Ive never heard of problems with these two coils other than the WOT is heavy.
Ive also never read about problems with the SEFs but I had one that falsed like crazy on wet sand at the beach. Ive since had several others and have three now and they all perform flawlessly. my only real complaint with them is there design is a little tougher to swing in the water, a round coil is easier to push though the water, so if wading is something you do often consider that.
an S8 is a good accessory coil also, nice and light and gets good depth and excellent seperation. also its waterproof and round

The S-12 is still tops for the water because I can tell you the 12x10 doesn't swing too easy for my tastes due to it's drag/squarish nature in the water.For land though seems the trend is towards the 12x10, for some anyway. Far as the 15x12/WOT thing, the WOT is about the heaviest coil made for the BBS units. The 15x12 without coil cover is lighter than the 10" Tornado with coil cover if memory serves. Check the coil chart in the coil sticky. I think the weights in that chart also show the 12x10 without a coil cover is lighter than the S-12, which is a statement because the S-12 is known for being a light coil.
I found the 15x12 was too big to show gains in depth on coin/ring sized targets over my stock 10" Tornado in my mineralized soil, but it did get deeper on my mineralized beaches...But the 12x10 is deeper than both for me on coin/ring sized stuff. Some get more depth with a 15x12 over stock on those sized items. All depends on the nature of your minerals IMO, because there reaches a point in coil size where not only do they lose sensitivity to coin/ring sized targets, but also will actually lose depth due to washing out the target by sucking in too much ground matrix. All depends on the soil you have. About 12 or 13" in size appears to be the limit for my soil, but even in better soil 14 or 15" in size is pushing the small target sensitivity thing for a DD coil. Concentrics seem to peter out at about 10 to 11" or so in max size for coin sized targets, but even DDs have their limits on that.
I've dug plenty of silver quarters and also 4 or 5 halves with my 12x10, so I'm not seeing any nulling issues with mine. Think I'll air test it and see if somehow that shows up in an air test, but never saw a problem air testing various larger coins like large cents/tokens/etc. Just don't remember if I air testing a silver quarter or half with it, but I have dug a good many with it. One recently a 1921 standing liberty quarter in F-12 condition that a few other machines had missed gridding out a front yard from two directions before I got around to hunting the site myself, and a small handful of wheats and other coins too they missed. Best coil I've ever used, and I'd swim over seas if I had to to get my hands on another one.
But the Ultimate may be just as good or very close. Still testing that between the two.It might be as deep or maybe deeper (don't know yet), and it does separate very well, but I doubt it separates as well as the 12x10 just due to the unique shape of the SEF coils that really compresses the width of the DD line.
The stock 10" Tornado is one heck of a coil too though. It's the best stock coil I've ever owned on any machine IMO.
