13" Ultimate Coil vs 10x12 SEF Silver dime trio & Colonial Button

Greetings all. Finally got my 13" Ultimate coil in the mail on Saturday, after 1 month+ of waiting! Got out briefly on Sunday to try it out. My first stop was at a very hunted out Union encampment. First few signals were trash so I decided to move from that area and as I did I noticed that the mix of signal tones became almost nonexistant, except for some occasional high tones that I could never seem to chase down. I swung the coil for probably 10 ft. square and had all but decided that the coil was all hype....then I looked down and discovered that I'd left the switch on my pinpointer on!!!! GAH I havn't done that in a long time!! LOL In any case, no good targets at the encampment other than 1 small piece of camp lead, but I would have been very surprised to find anything (even with my pinpointer switch on off!). I'd covered that area with several different coils and from all different directions. Worth a try though. Next stop was in the field I'd been finding Colonial buttons in. The corn is really too high to be doing much swinging but I thought I'd hit one of the hot spots swinging sideways and see if I could find something I'd missed with the 10x12 SEF. Nothing for quite some time and then I did finally dig one nice, but plain, Colonial Tombac button. Iffy signal but repeated from 4 directions. It was probably about 8" or so deep so I can't swear to a difference in detected depth between the coils, and I may have just missed with with 10x12 due to swing speed the 1st time, but it was in an area of heavy iron concentration so finding anything there with that large of a coil was impressive. I can tell you, however, that the 13" is almost exactly 2 ounces heavier than my 10x12, I weighed them on a scale (2 ounces doesn't sound like a lot but it feels like a lot when you swing it for a while). The only other find on that short hunt was a small shot round ball. At that point I wasn't real impressed but gave it another go on Monday afternoon. Took the coil to a pretty much hunted out park. Every once in a while I find a silver here still but they are few and far in between. I swung for a while, dug some trash, and also picked up some litter. I spotted a trash can several feet away and figured swinging in that direction was as good as any. Half way there I hit a confused signal that fluttered every once in a while to 11-45, I got a good high tone in 4 directions so I figured it was worth digging. When I dug my plug and pinpointed, I discovered a nice Merc. at about 6 inches deep. Drop the plug back in and waved the coil back over the area and discovered that a second merc had fallen off the side of the plug and was laying on top of the ground. SWEET....1st 2 silver spill I've gotten in a long time (a '34 & a '36, both plain). I swung around the park here and there for probably another 30 minutes and on the way back to the van decided to go over an area I'd hunted many times with other coils. Got another confused signal that again flitted to 11-45 once in a while, and again a high tone repeated from 4 directions. Dug down and about 5 inches deep was a beauty of a 1916 Barber dime on edge. SWEET! That was it for my time and I headed to the house with a 3 silver day, my first in a long time. SO....my opinion of the 13 incher is that it is a bit heavier than my 10x12. I don't find it as easy to pinpoint with, most of my targets dug were not in the center of my plug which is rare for me. In fact, the nicer of the 2 mercs, the '36, has a little ding in the side where I hit it with my digger GRRRRRR. Also, as Bryce noted in his trial of the coil, if the signal doesn't repeat from 4 directions, it was usually trash. The barber actually repeated solid from 3 directions, the 4th was "spotty" due to several other targets close on that side. I also dug a couple of Jefferson nickels and pennies, those are still in the pouch. I can't attest to added depth with this coil yet because nothing I dug was surprisingly deep. I'm positive that I swung over all three silver dimes, however, with other coils in the past so I guess I'm going to keep swinging the 13" great white hope for a while and see how it does. Am thinking about spray painting it black, though, if I keep it. That white sure does get dirty quick! OH....and the birdpoints in my pictures came from my early Monday morning hunt in a different field.....eyeball finds of course, wish they made a detector for those!!!! HH To all!!
 
Not sure why the pics aren't showing but you can click on the "open image URL" to see them. Also, for those who wonder, the 10x12 SEF is a coil I almost always have on my etrac unless I'm hunting in high trash or an area I've already hit hard with it, in which case I'll sometimes go back over the area with the procoil in case I missed something due to other close targets. I'm not sure the 13 inch great white hope will replace the 10x12 as my go to coil, especially with the added weight, but I'm planning to keep it on the trac for a few more hunts yet to see if I can get any deep finds with it.
 
Thanks for this! I haven't read it yet as I'm printing it out to read over a cigarette. I'm a big fan of the 12x10 with it's increased depth and jaw dropping separation abilities over my stock 10" coil, so I've been eargerly awaiting somebody to compare it to the Ultimate in those respects. As said, haven't read your field test yet but by first glance it appears like it may be the kind of comparison of these two coils I was looking for. Thanks again.

After reading it if I have any remarks I'll post them. Thanks.
 
Just read your excellent field review thus far. Thanks for that. Sounds like it has some good ability at seeing coins on edge like the 12x10 does. I've dug way more coins on edge with the 12x10 then I have with my stock 10" coil. I see you didn't really remark either way yet on how you feel it's separation is compared to the 12x10? What I suspect (?) is that based on the unique shape of the 12x10 that really compresses the width of the detection field it MIGHT have better left/right separation than the 13" coil because the Ultimate is a round coil? Or at least just based on the fact that the Ultimate is 1" longer and 3" wider than the 12x10?

HOWEVER, from what I've read so far on the web the 13" Ultimate appears to have some very unique abilities of it's own in unmasking coins in iron that you don't usually hear about on a conventional round DD coil. Certaintly not one of that size, so I'm in no way knocking it's unmasking or separation abilities here as it sounds like it does some things a conventional round DD coil won't do in unmasking coins in at least iron and such.

Besides, far as I know nobody has yet tested it against the 12x10 on undug targets to see if one separates or unmasks better than the other in certain ways yet, so it's really anybody's guess right now about just how well either one does against each other. Who really knows yet? Nobody.

I'm of course also looking forward to any comparisons of these two coils in terms of depth on undug targets. From what little Bryce has said thus far in the Explorer forum if I remember right he said up until the 13" coil he had never used a coil that made deep targets sound as loud as the 12x10. I can't remember but he might have even implied (?) the Ultimate made deep targets sound even louder than the 12x10? All I remember reading was that he was quite impressed with the volume of deep targets using the Ultimate, so read into that what you may or shoot him a PM and find out the exact details on that because I'm going from memory and could be wrong in what I recall.

Either way, there's a "hint" there that could possibly mean the Ultimate coil is just as deep if not possibly (?) deeper than the 12x10. Don't know, and am eagerly awaiting any in field tests of the two on depth and separation abilities. Of course that's the only way to really prove one way or the other just what the truth is.

I can throw in one tid bit somebody in the Sovereign forum said who really seems to like their Ultimate coil so far. They mentioned it tries to float a bit in the water but that it wasn't really too big of a problem.

My only concern is that in my soil I think either 12 or 13" might be the max coil size to still see gains in depth on coin sized targets. I found the 15x12 got less depth on a dime in my soil than the stock 10" coil, while some people say the 15x12 is deeper in their soil on coins.The 12x10 is deeper than both the 15x12 and stock 10" coil for me though. I suspect with my somewhat mineralized soils at some of my sites the 15x12 was just soaking in too much "ground stew" and thus degrading the target signal, even though it would run at high sensitivity settings. I found a much lower setting than what was max stable seemed to give me the best depth with it. Probably because running it too hot was taking in too much ground. So I suspect that it's either 12 or 13" in terms of coil size to still see improvements in depth on coins in many of my site's that have a bit higher mineralization than some of my other sites.

Once again, thanks for the field report and please keep us updated! :thumbup: This is the kind of stuff I love to read.
 
If anybody wants to read further on this coil here's a couple of field reports from Bryce and his initial thoughts so far on it compared to the 12x10...

I think part of the off center pinpointing is the result of coins on edge.I have been digging a lot of silver and other coins at moderate depth but on edge with this coil. Just dug a nice Barber dime today with DrBob watching that was several inches right of pinpoint in side wall of hole.Found it with my uniprobe pinpointer and took a big slice out of side of hole and their she was almost strait up on edge at about 6" . Have repeated this scenario numerous time with the Ultimate 13" coil.
Also have been pulling a lot of silver and Indians out of heavy trash with it along with some real deep stuff.What else can I say, this coil has impressed me a lot and is my main coil for most sites I hunt.Just today Dr.Bob had a couple of very iffy signals in extreme trash that he could not nail down with his 13x13 Neeel Tornado coil and I was able to isolate and pinpoint both targets dead on with the Ultimate 13 . Neither were coins but both were in the coin ID range :thumbup:
 
I can vouch for that. I have not used the Ultimate but have been impressed with what I have seen it do on Ray's machine while comparing signals.
 
Nice hunts!
Thank you for the honest and unbiased information.
I am curious of the depths on this too.
Maybe, you can try an old field somewhere--that may have some deepies and really put it to the test?
