Anyone up to expressing their true feeling about the 13" Ultimate DD

What is your feeling about this Coil especially at the beach. Do you feel that you are getting more falsing ?? Do you feel that the coil is lighter then the rest...... I can tell you one thing it gets heavy quick when the sand builds on the cover (bad design) everything goes against what I'm really looking for with this coil. Maybe on land it's good. I have my own thoughts for the beach, anyone agree or disagree. I see problems with this snap on cover !!

Ron iam not really sure what you mean by cover ? if your in water sand cant build up on the coil , it isnt any differant then most other coils IMO in design and weight as far as falsing what machine are you using and are you in ocean beaches or fresh water beach . Jim
 
Yea, as I noted in my review field reports of it thus far, the coil cover doesn't ride high up the side of the coil, and since it's a thin coin (thinnest spiderweb coil I ever saw) there isn't much height to the coil cover to keep dirt or sand from getting in. There is also a bit of a "lip" there and I found that in just some simple testing for 30 minutes in one spot on the forest floor of rotted leafs/black dirt, there was already a sizable amount of dirt stuck between the coil cover and the coil. Not really an issue IMO, because I never use coil covers and instead spray the bottom of my coils with 5 or 6 coats of spray on bed liner, letting them dry well between coats, in order to protect the coil. It's lighter than the coil covers too. A few grams at the most, while coil covers can weight several ounces or more. That may not sound like much but at the end of the day with that few extra ounces all the way at the end of your shaft you are going to notice it.

So far I haven't used the coil in the sand. I'd be warry of taking it in water since it's not rated water proof and so probably isn't filled with epoxy (thus it's super light weight for it's 13" size). Especially if you are a scrubber in the sand I think you'd risk wearing a hole in the coil that water might get into.

If you search back about two months or so in this forum for "Ultimate" you'll find two guys who were lucky to get their hands on these things very early on from over seas. They seemed to like it in the sand. I would read their reports to judge how well they said it worked compared to other coils, but if I remember right they seemed to like it for sand and water use.

Again, seal under that coil cable nut and rubber cable sleeve with Shoe Goo or something if you are risking water use. At least make sure the nut is tight by hand and then turned a hair more with a wrench (not too much or you might crack it). The one I am being loaned had a very loose coil cable nut on it, just like the SEF coils when shipped. I didn't muck with it with a wrench or anything since it's not my coil, and also because I won't risk using a loaner coil in the water.

I'm going to get around to testing this coil against the 12x10 more pretty soon here. More marking undug targets with poker chips in the field, and also want to test them against each other on some fine gold like small earings and some gold chains to see if one is more sensitivity to tiny gold stuff like that perhaps.

All the rest of my impressions of this coil so far are down the forum a page or two maybe, so I won't rehash all of it since it's already there.
 
I'm hunting in salt water ...The cover isn't like other covers . It's a snap on coil cover and that causes sand and water to get in very easy. This will cause falsing all the time. So I ask myself what was the big hype on this coil. If your hunting the beach and by the water save your money. It might be a great coil for the semi dry sand or great for land detecting but not for the water. Maybe mine is defective I don't know. I think when I bought it I should have been told that it isn't good for the water, being that they know this is the only detecting I do. Sometime you think you have a relationship with people you buy from but that isn't the case all the time. Critter I hope you can prove me wrong.
 
Yea, I thought I mentioned in the initial impressions and field test thread that the coil cover didn't seem the most sturdy I ever saw, and that I could easily snap it off with my fingers. I'm pretty sure the SEF coils go all the way up the side of the coil? Or if they don't for sure they are taller and also don't have that "lip" at the edge, because the SEF coil covers go straight up where as this cover is kind of curved.

So far it looks to perform well on land. For sure makes deep stuff sound a good bit louder than the 12x10, but the 12x10 also makes deep stuff sound louder than the stock 10" coil to me. Still got to test more on undug fringe depth stuff though to see which might be deeper than the other. The 12x10 appears at two sites thus far to allow you to run the sensitivity higher (in one case all the way full blast while the Ultimate I think could only manage a noon setting if I remember right (look in the review thread)).

Also the 12x10 appears deeper at a lower sensitivity setting when I tested on a dime, but I want to do that test one more time to make sure. I kept lowering the sensitivity on the 12x10 until I just lost the coin no matter what sweep speed from fast to super slow, then I threw the Ultimate on and it could not hear the coin, so at least it appears it's no deeper at the same low sensitivity setting because I didn't touch the dial. And it appeared I had to raise the sensitivity a good bit before the Ultimate would finally make any kind of response on the coin above where the 12x10 just lost it.

But as I said maybe at higher sensitivity settings the Ultimate is more "in tune" with it's design and might take the lead on depth. All I know is the 12x10 is going to be very hard to beat on depth and separation, but I will say so far this Ultimate seems like a fantastic coil and if I didn't have a 12x10 I'd buy this thing. It's 13" size at no real heavier weight than the 12x10, which are both lighter than the 10" Tornado, is reason enough for coverage. Got to get around to more tests on that coil marking undug targets with the 12x10 first at depth to see if the Ultimate can hit on them with both maxed out to the edge of sensitivity they can ride. Probably head back to one of my favorite known deep coin sites.
 
Your right on the sensitivity setting, even on the beach noon setting is my spot forget about 10 and 11 o'clock it will start to false on you especially if the coil has been in water ! It's ok if the targets are there but I don't know what I'm really missing since I took the 10x12 off. It does try to act like the Sef 10x12 but has that down fall when wet. I would like to take the coil cover off, but did you see how fragile the bottom of the coil looks when you compare it with other coils big big differance....What are they trying to accomplish here with the word Ultimate.....Ultimate what ? I'm not doing this very long but have 3 coils that are nothing like this in nature. I'm going to still work with it, and see if it lives up to it's name. I'm not going to talk negitive about it anymore I said what I had to say. I will give it a good run in the next couple of months. Waiting for your results.
 
I've had one on an Excal for several months now, it's not very stable in or around the salt water!

I'll keep it on till the end of summer then maybe try the 10 x 12.

I believe we have covered this topic before yes?

13 Ultimate on the Excal

13 Ultimate on Excal
 
I didn't see your post until it was too late. Should have done my homework.
 
How did the SEF 10 x 12 do in the salt water? I'm ready to pull 13 off as soon as can find one,
 
You will love the coil get it !!! I thought the 13"ultimate was going to be better but I was wrong. I have no problem with the 10x12 by or in the water
 
I've never used the 12x10 in salt water, but I can tell you this coil is the most stable coil I've ever used over rough ground or heavy iron trash. Smooth as butter, and allowing very high sensitivity settings too for that reason. So I would suspect it's probably very good in salt water. I can say on my beaches it runs smoother in those mineralized grounds then I would have dreamed, having owned and used many machines over the years on them (including FBS units). The stock 10" Tornado was also the smoothest over that sand and soil I ever used, it's just that the 12x10 takes it up a notch in all aspects. If I couldn't have the 12x10 then I'd only want a 10" Tornado on a detector. Still seeing how the Ultimate pans out here in testing but in all respects it looks to be a very good coil. If the 12x10 wasn't around, then I'd for sure want to try an S-12 too, and see if it or the Ultimate would replace my Tornado, but beyond all that I'd be very happy with the Tornado if I could only have one on an island, compared to all prior coils I've owned on various machines, except the 12x10 of course. If the Ultimate or S-12 pans out to be better for me in my soil, then it'd be one of those maybe. All in good time of testing here for me...

Just wnat you to know the 10" Tornado is one heck of a coil. Very deep (deepest coins I ever got in my soil before I strapped a 12x10 on), excellent separation, quiet, smooth, and so on. It's an awesome coil, and Minelab should be congradulated for putting such a fine coil on the Elite and GT.
 
Hey Ron hope your good. I know broken ribs can be very uncomfortable at time. Had that problem once many yrs ago. They taped me up but they don't do that anymore. I would make good friends with that horse before you try again. Good Luck ! Ron..... Very grateful for your help
 
Took my GT to the beach with the 13" Ultimate coil installed. Played with it for about three hours. Found some clad and one junk ear ring. Coil seemed to be especially sensitive to changes in height off the sand and to changes in angle. I could run it with sensitivity set at about 2:00 and had very few falses except when I changed the height or angle of the swing. When I transitioned from the very wet sand to where the sand was beginning to dry out then the falsing was horrible. Had to put the sensitivity in auto or lower it way down to keep the falsing down. The one thing that I noticed was that deeper coins seemed to be louder with the Ultimate than they were with the standard 10" coil. Havent tried it on dry land yet with the exception of in my front yard. It seemed to behave itself pretty well. Located two zinc pennies that I had missed with the 10" coil.
 
I have used the Ultimate at the beach since I got it. Took a while to get used to the size of the rascal after using the standard 10" coil. On the wet sand I can run the sensitivity at anywhere from wide open down to about 11:00. On the dry sand I may have to lower the sensitivity just a little lower. Once I get the sensitivity set for the conditions the coil rarely falses. My last two trips the majority of things that I have found have been DEEP. For a time after Sandy went by and removed some sand from our beaches I was finding lots of coins etc that were withing four to six inches of the surface. Now that the ocean has moved some sand around I am finding that most of my targets are deep. Critterhunter I took your advice and put shoe goo on the connector to add just a little protection from the water. The coil works well for me and meets my needs for a larger coil. If my targets were any deeper I would not want to have to dig them. I just wish that the coil had been made waterproof instead of just water resistant. I have not used the coil to any extent on dry ground as we have not had any rain recently and the ground is dry. I do not want to go digging holes and killing the grass in the areas that i have available to detect. I did spend a few minutes at a friends place that he said "There was an old building. He does not know if it was a house or a hunting camp. I did pick up three interesting signals from the gt. Wish it would rain.
 
George, excellent read and thanks for posting more of your experiences with the Ultimate. I always love to read coil field reports to see what people's opinion and experiences are with various coils in contrast to each other.

When I get one as my own I'll also be doing the Shoe Goo thing under the coil cable nut at the coil, but I'd warn anybody doing that that it might void their warranty. I'd at least make sure the nut is hand tight, because I found on the Ultimate and the SEFs the nuts are often very loose from the factory. The safe advice is to only hand tighten the nut, but I go just a hair more after hand tight with a wrench on my my coils after I've Shoe Goo'ed under the nut's top and on the threads.

Since the Ultimate I was using was a loaner, I only made sure the nut was hand tight and didn't push it further, and I didn't want to risk using that coil in the water. I'm not even sure if I'd risk using the future one I own in the water, but I hear others are doing that with no problem.

I can't tell from your post if you used yours in the water? If you did, can you comment on it's drag compared to the 10" Tornado? The Ultimate is the thinnest DD coil I've ever seen height wise for the Sovereign, so I suspect that combined with it's round shape might make it surprisingly little drag. I'm real curious to hear how it compares drag wise to the 10" Tornado from people who have gone swimming with it.
 
I have not put the Ultimate in more than an inch of water and that was just to wash the sand off. Since it is not waterproof I do not want to risk getting water into the coil. Being an old Retired Rascal I find that my finances do not always meet my wants so i try real hard to protect those items that I am able to purchase. I do like the Ultimate coil. I am finding things deep enough that I am sometimes in awe of just how deep the item was located. Since I am working on the beach lately I dig those IFFY sounds. I usually find a deep clad coin. On another subject. Is everyone at Minelab shorter than 5'11". After a few hours of swinging the coil my back eats me alive. I guess I am going to have to find a longer lower shaft.

Hey George I have a 13" Ultimate I still haven't got out to use....BTW I have a 30" lower shaft (fits sovereign)up for bids on ebay here: coiltek lower shaft FREE shipping
 
I never use covers on any of my coils on any of my detectors. Almost every cover collects dirt and sand and will cause false readings.

As far as telling the truth, why would anyone lie about a coil? What is to gain?

So far, I have had it for a few months now and I can say I like it even better than my WOT that I sold. It is as deep as the WOT in my neck of the woods and in my ground conditions.

It seems to be more stable and I can say that it seems to be more pronounced on deeper targets than the factory 10 or the WOT. I find Id'ing the target is easier with the Ultimate.

I have hunted in fresh water with it and as far as being water resistant and not water proof, so far I can say that at the depths I use it, which is no deeper than 4 or 5 feet, (Average swimmers depths), the coil did just fine. I've not had one problem with water getting into the coil even after many, many hours in the water at those depths. Now if I were to dive with it, then I might worry. It sure would be nice if Detech would put to rest the worries of some by making a statement about the Ultimate 13's water abilities.

The one thing I don't like is the white color. It gets dirty pretty easily and is hard to clean. But I can see where in daylight, the sun could play a role in the ability of the coil to be stable as some White's users have found to be the case with the black Ultimate that was made for their V3's.

I have not used it in salt water as of yet but will give it a try this coming winter in Florida. I will also just in case bring with me the factory coil if it has a hard time in the salt water.
 
I find it odd that any company today would even produce a coil that wasn't waterproof, especially for a unit like Sov that really shines in a wet sand environment.
