WILL THE METER WORKS WITH THE WOT 15" COIL on the GT?

I just purchase a new 180 meter and I'm thinking on bying a WOT 15" and SEF 12X10 coils for my GT, I dont whant to invest if is not going to work on it.
Thank you!

I have always had the 180 meters work with all but one coil. That was the S-5 from Sun Ray. It worked at first then kinda went nutty chirping.Of coarse each coil will require to be calibrated. Not even a problem. I have 12x15 sef minelab 8, 10, 8, newyorker horseshoe S-5 S-12 don't know if I ever remember having a problem with any, other than that S-5 I will give it another try.
 
Thank you for your information Buried Crap,I forgot to specifide about the meter it is a Digisearch 180 Target ID Meter and I know there are several types of meters outhere.
 
The only meter that won't work with a certain coil is the Insight internal meter when using an SEF coil. It will work fine it's just that you won't get any target IDs. There is a potential fix posted for this.

All the other (external) meters for the Sovereign will work with any coil, including an SEF.

I have an S-5 and it works just fine with my 180 DigiSearch meter.
 
Critterhunt, Thank you for thisone too! now I will have to make my mine betwing the SEF 12X10 and the WOT 15". any coments on this? in the accesoris clasiffide section is one WOT for 190 and I read on your coments that the SEF is going for 144 and no shiping.
 
Personaly I've never used a WOT and there are some big fans of that coil. However, it's a conventional double D coil. The SEF coils are a morphed DD/concentric design (mostly DD) with a real narrow detection field, meaning they have outstanding seperation. Big question to ask yourself is what you are going to be hunting? If it's wide open areas with little trash then the WOT or 15x12 would be a good choice for the coverage. If you will be hunting areas with trash then the 12x10 would be a better option. It will get deeper than stock. There are also fans out there of the S-12 sunray coil, but again that's a conventional DD coil so I doubt it has as good of seperation as the 12x10. I've never seen a coil with this good of seperation in the left/right perspective. It's even better at it than 8" concentric coils I've used on other machines. Although even the middle of the SEF coil has excellent seperation, I like to wiggle the front end of the coil at targets to seperate them even better. It feels like you are using a scapel it's so sharp.
 
HO nice, you have convensced me, i will get that SEF, it is only for coin/park hunting so should be perfect for it.
Thank you Again Critterhunter.

Coils are either a DD or concentric, not a combination of the two. The difference in a round DD vs an elliptical is the shape, whether it is a SEF or elliptical. The overlap in an elliptical or "elliptical" SEF may be slightly tighter in the detection zone so theoretically a slightly narrower signal may give a slight advantage in cross separation. However, the length of the coil signal will still be the same given same coil lengths. One advantage of rounds vs ellipticals is the round DD of the same length as the elliptical will normally give an overall depth advantage - example a 12" X 10" elliptical would be comparable depth wise to an 11" round DD. There are other factors at play which would concern the construction of the coil itself but that is the general comparison. The main advantage of an elliptical/SEF is the ability to be swing between narrower obstructions since it is thinner across than the round. Gold prospecting detectors usually have elliptical coils available for getting between shrubs, rocks, etc. Hope this helps.

Ralph, thanks for chiming in. So are you saying that Detech isn't right when they say the SEF is a morphed combination of DD and concentric design (mostly being DD)?
 
Here is what they say about the SEF coils...

"What does an Excelerator SEF Coil do? It creates a Symmetrical Electromagnetic Field uniquely combining both DD ( Double D) and Concentric detection signals resulting in your detector getting the best sensitivity of both types plus greater depth!"

I noticed that if you look at these SEF coils they have a center to them that is like a stretched out circle. That's where I would assume the concentric signal (if there is any) is generated. Any other conventional DD coil I've seen doesn't seem to have this unique center to it? From the feel of this coil to me it has a concentric signal in the center about the shape and size of a medium sized soup can, while it's a thin DD detection line extending out to the front and back from there.

Obviously being a coil manufacturer you know WAY more about this stuff, so please educate us some more on this.
 
As I said in my previous post it is either wound for a DD configuration or a concentric. DD are two D windings back to back which overlap each other. A concentric is two separate windings the outer being the transmit and the inner being the receive winding. Unless the SEF has a separate winding through the middle and then connects to an overall outer winding it is a DD. If it does have a separate winding through the middle (narrow oval) and then connects to the outer "circle" windings then it is a concentric. An example would be the Fisher 10.5" wide scan concentric for the CZ models. Now, DD windings can be manipulated into various shapes, etc.and marketed differently but they are still a DD coil none-the-less not a combination DD/Concentric as far as winding configuration goes. Our original S-12 DD Unltra Depth coil which was a pancake type coil with a solid housing, also had the
DD crossings in more of a football shape through the middle as opposed to the later open version which is narrower through the center for lighter weight, requiring less epoxy. We also increased the overall diameter to 12.5" vs 12".

Wow. that was intence information. thank you for all that enlighment it is great to now from the manufactures what are we using and I think with this info we will have a better prospect and undertanding of what and how to use them.
thank you Ralph and Critterhunter!
by the way I call Kellico and they don't have or sale the 12X10 anymore ( one of the sales persons tell me that) is there any other venders here in US?
Ralph do you have this particolar coil on stock?
 
The S-12 that Ralph sells is by far the best bigger coil for the Sovereign I have ever used, I tried a few others and didn't feel they were as good as the S-12 for me as i do land hunting. A few of the guys that do fresh water hunting in our club also preferred the S-12 over the other bigger coils they have tried.

Thank you for all your imput on this, it is great to have all those experiences and preferences on the use of each coil, the only coil that I have ever use on this machine is the stock 10" and works bery good for me but I just order the 12X10 and I will try it ass soon arives and the wether clears out.
