SEF 15x12 First Hunt! She's A KEEPER!

Warning: Long and mostly pointless ramble, but a good read if your out of sleeping pills. Skip towards the end if you want to know how this novel turns out.

Yesterday was about the first day in roughly two months that I was able to get out due to the snow cover and weather. We had a day in the low 40's and my friend and I figured we might find an area somewhere where no snow cover was present. After driving through a park for several miles we noticed a patch of green grass about 20 yards wide and 100 yards long at the edge of a sports field, but this area also serves as a picnic grove. This would be my first hunt with my custom lightweight GT using my own upper/lower shaft, grip, remote pinpoint, and meter mounted on top of the grip. It would also be my first hunt with the SEF 15x12. Combine all that with not being able to hunt for a long while and needless to say I was excited to get out and put this thing through it's paces.

Walking up to the green grass I instantly saw somebody else must have noticed this spot, because there were several unfilled plugs laying around on the ground. Not only that but this lazy bum didn't even pick up his trash. I re-filled his holes and picked up his trash. I think I saw the guy who probably did this when we were driving past a sled hill. That hill wasn't getting good sun so the ground there was frozen and it looked like this low life was using a pick to bust up the rock hard ground. If I see him again he's going to get a piece of my mind before he ends up getting us all banned from this park. You already have to carry a permit to hunt there so it wouldn't take much for them to ban us.

Anyway, despite that unpleasant experience I was still pumped about hunting. First off I'll say right away that this coil (at least on my lighter Sovereign with more weight yet to lose!) didn't feel as heavy as a stock GT with the 10" coil (which I knew it wasn't, but also feel it balances better than a stock GT). Keep in mind I haven't hunted in a few months or so and haven't been real active either, so I would have expected some arm fatigue. Yet, after about 3 hours of working this area I wasn't sore at all. If I was swinging the 10" on a stock GT I would have at least expected some arm discomfort having not been active for so long. The machine feels very natural and this coil does not feel big. In fact, after using it my 10" coil looks tiny to me and not "normal".

This area we were hunting has been well worked over the years by other detectorists. It's also heavy in clay so that I wouldn't expect coins to be rather deep over most of the field, at least in this area where there would be heavy foot traffic causing compact soil. It also is an area that has a lot of pull tabs and other trash. Combining all the above conditions (shallow coins, heavy trash) you wouldn't think this coil would be the best pick for such an area. In fact, had I known we were going to end up there I might have opted for my S-5 coil that would seperate targets best and still be able to reach what I expected to be less deep targets. Boy I'm glad I was "stuck" using this SEF coil yesterday!

On to my first impressions of this coil. Setting the unit up with zero discrimination and notch, threshold on, discrimination Iron Mask On, noise band 2, I was pleased to find I could set sensitivity at it's full highest level and the machine was still smooth as butter. No falsing or chatter at all. Very impressive, because although I can often do this with the 10" at areas that aren't near electrical lines or high in minerals, I would still have figured this larger coil would be picking up more noise and thus might never be able to run at full sensitivity.

Sweeping around the area I started hearing a lot of tabs, foil, and other junk. Since this was near the edge of a ball diamond I thought it might be a good place to find a ring as well as some old coins, so I opted to run my notch at 152.5 to 165 (killing about 84% of tabs...see "Splitting Hairs On Rings" thread) and my discrimination up to kill everything below 90 on the VDI. I like these settings ring hunt in high trash areas that I don't plan or have the time to dig every signal out of. I mostly never use any notch or discrimination when old coin hunting only because I like to hear the layout of targets and avoid masking.

Before going to the notch and discrimination I hunted for a while and found that the audio of this coil is like what others have said. It seems better than "normal" DD coil designs, bringing out richer tones and more solid locks. The VDI also seemed to be more stable, though I've never had any complaints about that, thinking the GT has one of the best solid VDI meters I've ever used on any machine. Regardless, junk targets that aren't uniform in shape or are tiny such as round tab tails will still jump around a bit tipping you off to the fact that they are junk. The audio for those also is very telling, making a warbly sound, breaking up, sounding bouncing or harsh, and so on. Overall I'd say this coil does seem to give better audio and ID to targets. Not that the 10" isn't awesome already, but it just seems even better.

Also before going to notch/discriminate I tested it's seperation abilities in heavier spots of trash. I couldn't believe what I was hearing/seeing. I had heard some say this coil seperated as good as the 10" or Pro Coil but wasn't ready to believe that. Not only does it seem to me that it does seperate as good as the 10", I think it seperates BETTER! My friend was using a 6000 Pro XL with the 9.5" concentric coil. We checked several coin signals each other found and I could hear every one he found mixed in with trash. More exciting information on it's ability to unmask or seperate targets is found further down in this review.

After turning on my "ring" mode settings I continued to search looking for any good coin signals or solid, smooth audio/vdi lock ons of everything else that fell outside of my notch or discrimination settings. Now I wasn't being distracted by all the tabs or foil bits and could concentrate on everything else. I popped a nickle that I knew was just that, and a few other tab tails that I knew would be those but wanted to be sure since I was a bit rusty and still don't have a ton of time on my GT since late last summer.

How's the pinpoint? Again, call me a liar but I think this is also BETTER than the 10". I used the reverse walking technique where you wiggle the coil back and fourth as you walk it back towards your feet until you just lose the signal. It should then be right at the base of the "V" where the two coils meet at the top of the coil. Every target I pinpointed with it was right on when I got down and checked the top of the ground with my ProPointer before popping it with a screwdriver. I was NEVER off, even though I have been with the 10" on occasion as I'm still getting used to it's pinpoint. Even in trash I had no problem isolating and pinpointing the target I was interested in. It's a dream, and I'd dare say even more precise than pinpoint on the concentric Whites coils I've used, which I always considered the most accurate on the market at that.

While on the subject, this remote pinpoint switch is like putting mag rims on your car. It really sets this machine off and makes it a pleasure to use. Not only that, but I found the meter being on top of the grip was fantastic as well. Even when I had it elevated on the stock shaft before so I could see it, that was still in the stock area further down the shaft so not as easy to see from that distance some times due to light conditions and such. So long as I'm talking about those custom modifications I might as well say that the light weight upper/lower shaft really is working fine as well. Everything is stiff and rigid and the machine already feels much lighter and easy to use.

As I said, this coil didn't "feel" that big. I'd also throw in that anybody considering an SEF but has the same concerns I had about the 15x12 being too big should drop those worries right away and buy the thing. It's not nearly as heavy nor as big as I had pictured in my mind. I know know I would have been let down if I opted for the 12x10 in relation to the 10" coil I already have. They would be just too similar in size for me. Even with all that said the 15x12 isn't very big if you compare them both sitting on top of each other like I did in the other thread (link below). After you use this coil you'll wonder how you suffered with any tiny thing smaller than it. It feels that natural to use.

The only problem I had was when I bumped the coil into by foot I noticed it wobbled for a split second or two on the shaft. At first I thought this was the Whites Tall Man rod but then realized it was the two Whites rubber washers. A Minelab coil has a wider mount so I had installed two plastic washers between the rubber Whites ones and the shaft, causing the rubber Whites washers to stick further out of the mounting holes on the shaft then they normaly would. This is what is causing the "wobble" when the coil is bumped as the rubber is flexing. I think if I switch the plastic washers to the other side, meaning between the Whites washers and the coil it's self, this would go away. Now the rubber washers will be sitting further down in the mounting holes on the shaft like they should and not be as prone to flexing. All that being said the coil and shaft was still solid.

Back to the impressions...So I'm swinging around when I get a good 180 coin signal. There was some trash nearby but the target gave a good reading regardless of what angle I swept at it. stuck my screwdriver into the ground and out pops a clad dime and a round tab from about two inches deep, both exactly in the same location from the tiny probe hole. Hmmm...looks like this coil is unmasking coins even with a round tab right with them and still giving a perfect coin signal. Not only that but I'm running my notch and discrimination. Very good first test of that, but it gets better!

Later on I hit a real heavy patch of junk near a large tree. I slowly sweep my way through it and suddenly hit another good 180 signal. This one is a bit smoother/sweeter sounding and also bouncing up to 181 for a split second here and there. Hmmmm....I'm betting this one is silver I think. I sweep around it from all directions and she's still reading true and perfect. I want to soak it all in here so I start sweeping around it to see just how much trash there was and how close it all was to the 180 signal. I'd say the target was completely surrounded by trash for the most part. At least almost a complete circle of trash ringed around it's perameter within 1 to 3" away from it at various points. Around the 7 o'clock position there was a larger "tab" signal that looked like it was a large piece of aluminum or maybe 2 or 3 tabs laying together. The other trash the surrounded the target was smaller but just as close or even closer to it. I then decided to get sloppy with my sweep from several angles and see just how quickly I lost the target. Nothing doing! Didn't have to be right over it to keep the signal a perfect 180. It wasn't one of those things where you have to perch right on top of it and wiggle right there. I could swing at that thing like a drunken sailor and still get that signal.

Now to put it to a real test. I call my friend over with his 6000 Pro XL and ask him to sweep over the target. He worked it for a while from different angles, commenting about all the trash there, and then finally said "I can get a high dime signal, but only from one direction". He also remarked that he probably wouldn't have ever seen that signal unless he knew to be looking for it. That sounded to me like this coil is unmasking this mystery target and seperating the surrounding trash better than his 9.5" concentric, though I sure want to do further comparisons in the field to firm this belief up.

Long story even longer, I'm pretty sure this is a silver. In fact it was, and not only that but this would be my first silver coin with the GT. I've dug indians, a v-nickle, and wheats since I bought it, but I've had limited time with the unit so far due to the oncoming winter. I've dug a gold ring on a beach and a thin/tinny silver woman's ring at about 9" in the sand as well which was loud and clear, but I still haven't put enough time in to pop out a silver coin with it. Combine that with the fact that I would often grab my QXT Pro for my hunts in the woods due to it's lighter weight when on scouting missions and it's easy to understand why.

But I just knew this was going to be my first silver with the GT, so my friend watched as I dug a plug (the only plug I dug that day because of thinking it was silver, everything else I popped with the screwdriver) and right at the bottom of the hole about 3" down was a 1926 mercury dime! OK, that's pretty outstanding. 3 hours into a hunt with a machine I'm still not totaly seasoned on, and a coil I've never used before, at a place that's been pounded by many machines over the years, and there she is laying in the dirt at the bottom of the hole. Can't get any better than beating all those odds along with the trash that was masking it, right? Yes, it can! The dime was also laying half way on edge! Wow, everything I've read about this coil is being proved true to me in the first initial hours of use. How about one more thing to stack those odds? The plug had a beaver tail in it for the most part right above this coin by about an inch to two.

As anti-climatic as this is going to be, I might also comment that I found this coil hit loud and deep on tiny beaver tails and other small bits of trash. Oh, I knew they were trash by the jumpy ID and bad sound but I wanted to see just how deep it was going on those. While I wasn't digging to the limits because this location didn't offer that with it's compact clay soil, I was able to notice that these tiny targets were louder and easier to hit than with my 10". That speaks well about this coil's ability to see small targets like others have said.

So what do I think? It's the most stable coil I've ever used on ANY machine. It doesn't seem to false as much on iron. It gives enhanced audio and more solid or easy VDI locks without the need to go into "wiggle" mode as much. It pinpoints like a laser, better than the 9.5" concentric I've used on Whites or (I think) my 10" Tornado. It seperates better (at least it feels that way) to me than the 10", which I didn't think was no slouch at that either. It does indeed seem to umask coins that other coils, even smaller coils, have problems with. I'd say that's due to it's unique design which is even different than oval or eclipse DD coils to some extent. The "hot area" seems much wider in the center, sort'a like a small concentric in the very middle, yet having the typical DD thin detection line running out to the tip and tail.

As the title of this thread says, she's a keeper in ALL respects. I can't think of one thing I don't like about this coil yet. I thought I'd never say it, but this thing might just turn out to be my "all purpose" coil I keep on every day. Tell me why the 10" would be better for that? I can't think of a reason myself. Seperation? No. Weight? No. Pinpointing? No. What's the advantage? It may be that I use this coil as my every day coil and go to the S-5 when I want to really laser through the trash. At least I think the S-5 is still going to do a better job at that, but I will have to think about it...:smoke:

If you have been on the fence don't think. Just go out and buy one. If you only own an 8" coil then try the 12x10. If you already have a 10" then grow some chest hair and pick up the 15x12. Heck, now I'm even wondering just how well that 18x12 would do for more coverage in wide open areas. Naaa....I already feel like I'm covering way more ground quicker with this one.

Here's the exciting thing...All those old spots of yours.,,You know, the ones that you've hunted for the last twenty years and look fondly at like an old friend when you drive by but just don't see the point of trying anymore? Guess what? If you just picked up a Sovereign those spots are already new again to you. I gurantee you'll find coins deeper or more masked then you have with any other machine on the market. But now, here's the thing...One of these SEF coils makes that "new" feeling even more distinct. Not only are you getting deeper by all rights than anything on the planet, but you are probably going to unmask even shallow coins that some how your "average" DD and concentric designs just aren't hitting right. Oh sure, they'll unmask coins to and some are better than others, but I bet there are going to be a BUNCH of masked coins out there that those run of the mill DD designs don't like and can't reveal. Along with the deepest of the deep those are the coins that are waiting for me, and they'll be waiting for you when you strap one of these SEFs on.

It's going to take another twenty years for people to cover all those "old" spots again. Think about it...How many people buy aftermarket coils? Probably only 20% of the detecting public I think. Then ask yourself how many of those people are buying an SEF? Most of them will still think these coils are junk like the first aftermarket coils KellyCo sold years ago.

Then put some further thought into it. How many of those people are going to strap it on to a Minelab? After reading some of the Whites depth reports I don't see any thread there myself. Let's narrow it down even further...How many Minelab guys are putting one on a Sovereign? I've heard plenty say the GT seems deeper to them. I know it is for me than the Explorer was. Ever wonder why the GT comes with a 10" coil, the Explorer a 10.5" (? never measured mine), and the Etrac with an 11"? Maybe that's not by chance. Maybe they have to do that with the FBS machines to *try* to give them an edge?

Then there's the guys who say the Sovereign runs more stable allowing higher sensitivity and better ID and depth at many spots for them. We could also go into some posts I've read from guys who have owned all three including other machines over the years and think the Sovereign handles larger coils better with less falsing or interference.

But, I'm rambled on enough for one day and am now even further off topic than I normaly get. Before I put you to sleep, if it's not too late for that, pick up the phone and buy one of these coils! Everything old is new again, and I can't wait to "grow up" and cut my teeth on all my older spots all over again. Old friend here I come...

(This message is subject to alteration, change, or complete deletion within days when I've had more time to use this coil and find out all my first impressions were wrong. Not responsible for people buying junk based on my opinion.) :bouncy:
 
Meaning "Wow, what a post" because of the performance of this coil, or "Wow, what a post" because of it's length. Don't answer that, I think I already know. :biggrin:

Critterhunter, thanks for your very informative posts. I will be watching for your posts on the 12 x 15 SEF coil. I may have to buy one myself for my GT. GH, Don
 
Critterhunter,

Your enthusiasm is contagious. You have a neat tendency to think outside the box. And don't worry about your posts being too long. I enjoyed every bit of it. I also got a kick out of your disclaimer at the bottom. You can never be too carefull.

Looking forward to your next review.

Glad you liked the coil, you pass on my similar emotions better than i ever could, you even took me back to my first outing with this coil on the Elite in 2008, its a shame they don't make an 8x6 for the Sov like they do for the Explorer/etrac or you S-5 would probably be retired to 2nd choice
 
In the interest of full disclosure, I was just talking to my friend last night and asked him again about what kind of response he was getting on that silver dime. He says that he thinks he was able to get a response from it in any direction but that all the rest of his remarks above still hold true. Regardless of that, I'm still very impressed with how well this big coil saw through all that trash, and there are plenty of other reports on the web from people who give me confidence that an SEF will unmask even shallow coins or ones on edge that other coils seem to have problems with.

One of the things I have never learned properly is that brevity is the essence of wit. As the old saying from the great movie Blazing Saddles goes, I always like to keep my audience riveted. :biggrin:

You're missing the point...Nobody would expect such a large coil to even compete at separation or unmasking ability with something in say the 9" range, yet by all appearances this coil does! As I said, I think it might in fact be separating and pinpointing better than my 10" Tornado. I think this might be due to what I've heard others say- that the detection line of this coil seems thinner than even a smaller DD. That doesn't mean you'll miss targets, as the line is still going from tip to tail with each pass like any other DD, it just means that you can stick that detection line between some very tight spots. It seems much thinner than my 10" detection line, yet still is going VERY deep....from what I hear deeper than any other coil on the market for coin/ring sized targets.

I also think that at the center of this coil it seems to have a nice big round hot area about the diameter of a medium sized soup can. Maybe that is the "concentric" hybrid part that Detech hints to in their promotion material. That part allows you to just nick the edge of a target without fully sweeping over it and still get a good signal. I think that's why the coil will ID a target perfectly most of the time without getting into the perched "wiggle" over it, and also probably why I could sweep at the silver dime in a real sloppy motion and still pull a good 180 signal out of it. Yet, the separation is still there with the rest of the signal's detection line from tip to tail to offer extremely good separation and pinpointing, and is uniformly just as deep across the entire line and not just in the very small center like a concentric has. It truly does seem to be some kind of hybrid offering the best of both worlds.

Also, separation and unmasking can be two different things. A small coil is better at separation but not necessarily better at unmasking. It will "unmask" coins by virtue of the fact that it can isolated multiple signals. Some of what is involved in umasking a target is also how the coil's signal dynamics hit the target, and also what the machine does with the signal to separate two targets mixed together. With the unique field dynamics this coil seems to put out I hear it does indeed seem to hit better on certain coins on edge or mixed in with trash. Combine that with the Sovereign's excellent ability to process a signal that has a coin and trash mixed together and draw the coin ID out of the signal and I'm smiling from ear to ear on the potential of this puppy. It may in fact be able to unmask or hit harder on coins that even a small coil can't "see".

If I was going to compare to my friend's 6000 Pro XL using a 5.3" bullseye (which is actually I think 6.25" in diameter) I would be using my S-5, which is only 5.5" in diameter and a DD versus that concentric Bullseye. The story might come out even worse for the Whites in that situation. :biggrin: I've owned the 5.3" on some of my Whites and the S-5 is both deeper and better at separation.

I wasn't expecting any of the bonus features of this coil- excellent separation and pinpointing, smooth operation, enhanced audio and VDI, ability to unmask coins in trash or on edge (remember, unmasking ability is not based on separation alone, but how the signal hits those coins and "ignores" what's with it in the hole), and so on. All I wanted was the deepest coil on the market for coin/ring sized targets. Everything else is just icing on the cake.

By the way, I've owned a few 6000 Pro XLs (two I think) and even with the Bullseye coil they still are slugs in heavy trash to me due to the lack of multitones and the slow meter response. You have to constantly watch the needle and work it over targets to separate the good from the bad. That was my only major complaint with that machine and the reason why I sold it.
 
Here's a quick picture I drew up to illustrate what I think this coil is doing based on it's "feel" in the field. I might also mention that while the "concentric" part should keep you from missing targets near the center of the coil that you don't fully sweep over (in other words, you just hit the edge of with the middle of the coil without the target crossing the center DD line), of course the DD signal will also keep you from missing targets near the tip or tail since that detection line is equal in depth across it's entire thin length. That should be yet another plus to this coil- You are less likely to miss targets and not just based on the larger size of the coil, but also in how it's detection field is being transmitted into the ground.

I'll bet that this is also how this coil seems to unmask targets smaller coils or typical DD and concentric designs seem to have a hard time revealing. The unique coil dymanics might hit those more elusive targets in just the right way to ID them. I'm sure DDs, concentrics, ovals, eclipse, and even "butterfly" coils will hit on masked coins in their own special way as well, but since there are more of those coils on the market there should be more of those coins already recovered by people. By my way of thinking there should be a whole bucket load of other coins out there on edge or masked that have "SEF" written all over them. They've been saving themselves for that "special" coil. :biggrin:

Thanks guys. As they say the devil is in the details, or is it only devils deal with details? :biggrin: I always read those short little reviews and "how to" articles wanting more. I don't like to leave questions unanswered for myself or anybody else, so that's why I try to be real specific. The only reason why I "think outside the box" is because you have to in order to stay ahead of all these smart fellow detectorists. That's how I find my virgin spots or even unworked areas in the middle of "worked out" locations. Use your imagination in life as well as detecting and I find things much more interesting and productive that way. The disclaimer at the bottom was a purely a joke. Felt I needed to wake people up before they fell asleep on their computer. :biggrin: Besides, I don't feel I have much at this time that needs to be protected from others. :cheers:

Thanks. If you knew all that I just wish you would have done a better job of convincing me sooner about this coil. Open up a little and give people a piece of your mind. :biggrin: Yea, I'd like to see a small SEF. Perhaps a 6x3. Now that would be killer separation with the depth of a 6" and the separation of a 3". Does anybody make one of a similar size to a 6x3 for any machine?
 
Managed to get out for my second hunt with this coil a few days ago. This time we headed into the woods at a spot we haven't hunted yet. This area is near where an old road intersects a river. I was anxious to see if this coil was going to be usable in wooded locations. Based on my hunts with the 10" Tornado in wooded areas I found the 10" to be somewhat a pain to use due to the open faced circle design, causing me to snag the odd branch or other debri on the ground. It's fine to use, just more hassle than using a closed faced coil such which offers less chance at snagging things on the ground as you go.

The 15x12 was surprisingly less prone to this than the 10" due to the webbing of the coil which seems to more easily slide over the branches and other objects without it finding it's way up into the coil and getting hooked. Still not as easy to use in the woods than a solid close faced coil, but a mild improvement over the 10" to some extent. However, I did find that it's extra size (mainly it's length) made it more difficult to poke between trees or brush than the 10".

We mainly try to hit areas with older trees present and thus less ground weeds/brush since the shade of larger trees prevents them from growing there. In places like this where the woods were wide open I found the 15x12 really came into it's own in that I could cover a large area quicker without worrying about missing spots thanks to it's larger coverage than the 10". Think about it...at 15" long this coil is covering the same amount of ground in two sweeps that it would take three sweeps to do with the 10" coil.

This made for much faster and more thorough gridding of larger more wide open wooded areas. This is another added bonus to this coil. In effect you are increasing your sweep "speed" by a third (if I did the math right in my head, or is that 1.5X the coverage? Too early in the morning for me to make such computations). Of course you're not really increasing your sweep speed but you are increasing the speed in which you cover an area, so they both equal the same results- more coverage in less time.

I'm thinking about continuing to use it in wooded areas that are open enough. I'll switch to my S-5 in the really thick brush and stuff when I want to be able to poke the coil between things like that. The 10" isn't any less trouble for the most part than the 15x12. I'm thinking of cutting a piece of coruplast (sign material that looks like ribbed cardboard only it's plastic, smooth, and VERY strong) into the shape of the coil and then using zip ties to secure it to the coil for hunts in the wood. Corruplast is so smooth that it should slide over the ground fairly easy, probably even better than just using the stock coil cover.

As I hunted through this new body of woods my friend and I both found there to be a lack of signals for a while. Finally we arrived at a "corner" where two ravines created a bottle neck, pinching the higher ground into a span of only about 40 yards or so. As I suspected this concentrated activity because we were now picking up a lot of iron and the occasional shot gun shell. I swept through the more intense area of iron for about ten yards when I came upon the long awaited "180" signal. Checked it from all directions and it was a perfect 180 still. While it didn't bump up into 181 like the Merc I found the other day, it did still have the same softer/sweeter/less harsh sound of "silver", which I'm still learning on this machine but it's very apparent already.

I'm finding that if I calibrate the meter to 181 on a clad dime and then bring the adjustment down just enough to drop it to 180, I believe (still to early to say for sure) that a silver dime, clad quarter, silver quarter, large cent, half dollar, and silver dollar will at least bump into 181 here and there as you sweep. This makes perfect since because a clad dime would be just a tad less conductive than a silver dime, and so on.

So I'm thinking to myself..."Sure sounds smooth and sweet like my first silver dime with the GT the other day, better bug my friend to come over and sweep it." He looks at me from a good 60 yards away like I've lost my mind but decided to come over anyway. He sweeps over the target and says "It's just between a clad and silver dime on my meter (6000 pro xl), I'm betting it's a worn silver dime." I told him that was exactly my thought based on my very limited experience with this machine on silver thus far. He watched as I dug down four inches and out pops something silver in my hand. I wipe away the dirt slowly and softly and there it is- 1908D Barber dime, and it's pretty worn around the edges! Probably was dropped in the 1920's with that amount of wear.

Very excited about this coil now. Only my second time out with it and it strikes silver again. Yea, this coin wasn't on edge (that I know of) or very masked by iron or other trash this time, but it did allow me to cover that larger more open area completely in less time. After all, if you don't sweep your coil over a target you'll never have the chance to find it. Had I been using the 10" or a smaller coil I might have moved through this spot and onto the next good looking area further into the woods with out covering it completely. It's far less hassle or having to convince yourself to cover a spot when you know you can do it in less time with a larger coil like this.

This extra coverage should make hunting wide open large grass areas in parks, beaches, fields, and other such open expanses far less intimidating with far more chance to not just miss a target with your coil. It also makes it much easier to "see" what has been covered and what has yet to be as you sweep the coil around using it's larger size as a good reference point.

Forgot to mention the sensitivity. Once again the coil was very stable, falsing less on iron, and allowing higher sensitivity settings. As I worked my way into the woods away from the nearby road with electrical wires I was only able to have the sensitivity set to about the 11 o'clock position. Once I got another 80 yards or so further back into the woods it was full sensitivity all the time with no falsing or chatter. I really feel this coil is the most stable I've used on any machine.

This has got me to thinking...Most would say that a small coil is the best choice in heavy iron or high minerals. But, based on this coil's ability to remain stable in heavy iron, it's unique coil dynamics that might see or unmask coins that even small coils can't, and it's ability to run at high sensitivity levels even in heavy minerals, I'm wondering if this coil might prove to be a deadly weapon in those types of areas as well. I'm sure the S-5 will unmask (separate) coins from iron or other trash that other coils can't, but by the same reasoning this coil might also do the same in those areas that the S-5 and other coils can't on certain coins. If anything I'm thinking it's increased stability allowing higher sensitivity settings in heavy minerals should allow it to get deeper than other larger coils, where as it would be your first choice to go to a small coil to cut through the mineralization better but at the same time losing depth due to the smaller coil diameter.

I have a few high mineral and high iron sites that I want to run this coil over and see if it gets deeper in the minerals or unmasks coins in the iron that even a small coil couldn't. I plan to then re-work these areas with the S-5 and see if it can produce any coins that the SEF missed. Remember, I'm not saying that a large coil will separate as well as a 5" coil, but there might be more involved here than just that (coil dynamics "seeing" the coin laying with the trash, increased stability in high minerals allowing deeper detection than any other large coil, etc). This should all prove very interesting to test in these two separate site conditions- ones with heavy iron and ones with heavy minerals. I've got the perfect spots in mind for this.
 
Yesterday I managed to hit a local fresh water beach on a small lake near my home. A few months ago a friend and I had gridded most of this beach with my GT using the 10" coil and him using a 9.5" on his 6000 Pro XL. We managed a few rings and tiny earrings. This is the spot I dug a deep thin silver ring with diamond at like 9-11" which was loud and a gold class ring. My friend had dug a few junk rings at this place and a silver Rosie and a few wheats. Anyway, we also had seen a few guys using Fishers gridding this area on a few different days when we drove by. Keep in mind that it's cold around here so this beach hasn't has swimmers to re-stock the sand with items.

I didn't grid yesterday but rather just wandered through a few of the spots that I know we've gridded several times over let alone what the Fisher guys had done there. I found targets present with the 15x12 that I never even heard before with the 10". One round pull tab that was loud and clear was probably within five to ten feet of where my friend had dug one ring a few months back. I know both of us had walked right over this round tab. It wasn't all that deep but I *KNOW* we worked that spot several times digging everything. Perhaps it was sitting at enough on an angle to not give a signal before. I also dug some round tab tails very deep and a shotgun shell also very deep, deeper than I've ever dug one of those before anywhere. I knew the junk like this was junk based on the jumpy ID and/or warbly audio, but just the same I was hunting a beach and am not going to pass up anything above iron in this "cleaned out" beach. Within an hours time it started raining so I had no choice but to pack up and leave. While I didn't did any silver, I did dig several targets that everybody had some how missed before, either due to depth, tiny size, or angle of the target. Can't wait to get back there.

I found that I was unable to hunt with the sensitivity any higher than about the 1 o'clock position in the wet sand near the water, but that in the drier higher areas I was able to hunt with sensitivity at about the 10 or 11 o'clock position. This is a little higher sensitivity settings than I was able to run the 10" there at. Very impressed with this coil's stability even at this high mineral beach.

Glad you liked the coil, you pass on my similar emotions better than i ever could, you even took me back to my first outing with this coil on the Elite in 2008, its a shame they don't make an 8x6 for the Sov like they do for the Explorer/etrac or you S-5 would probably be retired to 2nd choice

Thanks. If you knew all that I just wish you would have done a better job of convincing me sooner about this coil. Open up a little and give people a piece of your mind. :biggrin: Yea, I'd like to see a small SEF. Perhaps a 6x3. Now that would be killer separation with the depth of a 6" and the separation of a 3". Does anybody make one of a similar size to a 6x3 for any machine?

I did try, but with so many favoring the Sunray S12 or the Wot 15" i was outnumbered(Thier loss :biggrin:) my only worry was that maybe on the other side of the water to me, maybe the ground is so much different that you wouldn't get the same results.
Anyway you seem to be doing ok with it:thumbup:

there is a 4x7 by detech for the explorer but no sure if they make it for the Sovereign
 
Maybe we should get a pile of signatures together and lobby KellyCo/Detech to offer the 4x7 (or something new yet even smaller) for the Sovereigns? I'm game if there is anybody else who wants to jump on board. I'll handle collecting the signatures (handles) and present it to them with a letter as to why we'd like to see a small SEF coil for the Sovereign line. While they might not want to waste the money tooling up for a totally new size coil, making a 4x7 for the Sovereign would be as easy as re-winded the existing coils being made. A 4x7 should have the depth of a 7" with the separation of a 4". That might even separate better than my 5.5" S-5 due to the squeezed with which would equal a thinner detection line.

I doubt there would be enough motivation from fellow Sovereign owners to try to get this ball rolling but I'm throwing it out there to see what happens.
