My opinion on the 12 x 10 SEF

[Jeff in Pa]

Before I start please remember that opinions are like... Well you know what I mean. I have put a decent amount of time on this coil now and figured I would post my opinion on it comparing to the Pro coil. First and foremost this coil goes DeeP!! Very Deep!
I was in a park just this evening that was full of coins, problem was they were clad dimes. I dug 8 dimes that had the meter either buried or all but and still it grabbed them easily. The sound it produces is very good, has that nice warble to it. It has good separation of targets for its size.

I started keeping my gain at 9 because I like it when the depth meter gets to the 3/4 mark I can tell the sound is getting softer. It helps so that I don't need to look at the screen so much. I personally think the pinpoint is not as good as the Pro coil but it definately runs smoother, falses less and runs at a higher sensitivity than the Pro coil.

I guess the things that I dislike about it are the weight although I have got used to it, and the pinpoint isn't as good for me as the Pro coil.I am not a fan of the shape of the coil. My eyes just prefer a round coil.

Would I recommend it, Sure would!!

Good review Jeff.

 

[Hotcz70]

pretty much spot on with anyone and everyone I know who's ever hunted with me and tried or used it....especially for the pro's you listed about it.

In the last 3 years or so I have received over 100 messages and emails from people who either tried a friends 10 x 12.....or bought one of their own...and I can state with all honesty that at least 9 of every 10 people who contacted me were happy with it after doing so....and were contacting me to simply let me know.

Thanks for sharing your opinions.

such a GOOD COIL!------Simply put, it just "flat out" finds stuff--lots of stuff (deep silver coins)!

You are right-on about the weight of this coil Jeff. I am preparing for shoulder surgery as I type this (j/k). Been using this coil for two years now, wouldn't go without it!

For my opinion on this coil- I absolutely LOVE IT! I don't understand how I could've missed all the stuff I'm finding with the stock coil on my XS, but that's the ONLY thing I've changed and I am finding crazy amounts of coins that I previously missed.

Just my 2 cents- and oh yeah, I found one of those recently too!

HH All,

My 10X12 gets used 99.9% of the time. I will only switch to a smaller coil if I am swinging in tight spots ..

 

[Dave-IL]

it hasn't been off of my SE since...and that's the truth.
When I first got into detecting a few years ago he said it was his favorite coil and that he would never tell a friend to try something that he didn't honestly believe would help him find more stuff.

I received mine about two weeks ago and LOVE IT, but I have one question. When I received it the nut where the cable attaches to the coil was loose, so I tightened it up and was very careful while doing so. There is still a gap of about 1/8th of an inch showing threads, will this affect it from being watertight or is this not a concern.

Nice assessment bud. I have the same opinions. Great coil.

They won't tighten down over the entire exposed threads, so don't worry about that. In fact, don't try to over tighten it with a wrench or something.

The SEFs and even the Ultimates are coming with the nut very loose usually or even all the way off. Nobody knows why they do that. Saving the manual labor of tightening them in production (I bet having that job would get old)? Keeping them open so they don't pressurize when in cargo planes? I doubt that, as the coils are epoxy filled (well, the SEFs are, but I don't think the Ultimate is), but I guess gases could still escape from it perhaps? Or, my best guess, is that they simply leave it off or loose to keep pressure off the coil cable when shipping, as I noticed the box isn't high enough and puts pressure on the nut in that respect.

Either way, regardless of why, and even though the SEFs are epoxy filled and thus "waterproof" rated, I'd still take the prudent route and tighten that nut. Some say only hand tight. I prefer that and then a slight bit more of a turn with a wrench, but not enough to risk cracking it. Just a tad. In fact, I do that with all my coils, and before doing so I coat the threads and inside top of the nut with Shoe Goo, to insure it's sealed no matter what against a leak. Why I do that, is because even if the coil is epoxy filled, I worry water might wick down the coil cable wires to further into the coil internals encased in the epoxy.

If a coil goes bad internaly, there ain't no way of getting to it, so it's pointless IMO to be able to remove the cable nut anyway. Only way I'm aware of and seen done to access the internals of a coil is by using a angle grinder to cut off the outer casing, and if the coil is epoxy filled then hope you can chip off enough at just the right suspect bad part to fix. Otherwise it's getting destroyed chipping away and searching for a fault.

If a short happens in the col cable it's usually either right behind the coil plug on the control box or right above and not under the coil nut on the coil. If a short happens under that nut it'd be so hard to get to anyway to fix and heat shrink that I just don't see the reason to insure I can reach that less than 1/8th inch or so under the nut to fix a short right there. What's the odds of that?

PS- On some of my coils, if the rubber coil cable sleeve that slides down with the nut is solid, I even stuff Shoe Goo into that to seal it around the coil cable. Double walled protection way I look at it.

Some guys are using the Ultimate in the water, but being that it's not waterproof rated I personaly wouldn't risk it myself. I suspect the reason why it isn't rated waterproof, and that of it's super light weight for a coil of it's size, is that perhaps it's not filled with epoxy. If that's the case then one pin hole breach in the casing and it might be lights out for that coil. I was even a bit worried using a loaner in wet grass because of this fact, but luckily it didn't have any issues. For sure if not using a coil cover then protect the bottom against wear via spray on bed liner or something. I wouldn't want to risk wearing a hole in the casing if I were a scrubber by not using a coil cover or some other form of protection to guard against wearing a hole in this coil.

I love the coil by the way, and when my loaner goes back to the owner I'm getting one to sit along side my 12x10. Don't know if it's any better yet or even as good as the 12x10 in depth or separation, but the somewhat improved coverage of the Ultimate for working bigger areas is reason alone for me to want one, though the 12x10 is still an improvement in that respect too. I owned a 15x12, and while it's a bit more stable than the Ultimate around EMI or over rough ground, the Ultimate's weight and "feel/balance" on the shaft is a big perk to me.

How does it compare to the ultimate 13" any bodr know?
