Is anyone in a position yet to compare the relative merits of the round 10" Excelerator DD coil that's been discussed here recently and of the equally new "butterfly" 10x12 SEF DD coil? Both are DD, both seem to give added depth. Is one superior to the other in some way, or for certain uses?

Merits of 10" Ex. DD coil vs. 10x12 SEF coil?
- Thread starter apikoros

I haven't been able to use a 10x12 yet but have used the 10". I know Larry has used both. I do know the 10" is a lighter coil only 1 oz more than the stock coil. The 10" has been a replacement for my stock and 6x10 coil. It is now my general use coil. Good coverage and more depth. Unless I get a 10x12 to test I would guess I would use it more for wide open spaces and if I remember correctly, I think Larry said it might get 1 inch more. Rob

The SEF 10X12 DD weighs 18.4 Oz with out the coil cover, as compared to other coils I have weighed.
White's 10" DD.........16.09 Oz.
White's 950..............17.10 Oz.
EXcelerator 10" DD...17.70 Oz.
As far as depth, I'm not sure, I wouldn't be surprised if the SEF has a slight advantage over the EX 10"DD because of the newer design of overlapping windings as opposed to windings side-by-side on the other DD coils. The overlapping winding design seems to be the design of the future and what testing I have done has given me mixed results. The SEF for the Minelab is getting rave reviews from users and the 10X12 I have seems to work OK for the MXT with what limited use I have with it. I will have to get Nancy to use it and see what she says. The problems I am having is on other machines than the MXT.
The SEF seems to be a bit quieter, rejecting mineralization better and because of the newer design, the "active" zone of the coil seems more concentrated which should result in better depth and separation. I will know more as I log more hours on the one I have.

Our scales vary a little but the 6x10 is 1 oz lighter than my 10". I think if they answer your post several of the regular people on this forum no longer use their 6x10 coil. I know on some forums I hear they use no other coil. First let me say I used the 6x10 coil myself. The reason I changed is the 10" is deeper then the 6x10 but separates about the same as the 6x10. Like you said 1 oz makes no difference to me. Carl, an engineer for Whites, has posted the 6x10 has a depth closer to a 6" rather than a 10" coil.
Now remember, I said the 10" is the coil I keep on most of the time. It is my regular coil and has replaced my 6x10. I was going to wait until spring to sell the 6x10 but if you are interested let me know. By the way, by the time you get your MXT they might come with a 10.25" coil instead of the 12" coil.
I'd like to try the 10x12 SEF but a 12" coil wouldn't be a coil I would have on all the time, if it was a SEF type or not. IMHO I think Whites has found out 12" is too big as a main coil and that is why they have come out with a 10". Is a 12" too big for a coil, NO. Is a 15" coil too big for a coil, NO. I would be happy to have one when I needed the extra depth. For my type of hunting it is too big for a general purpose coil. Rob

Thank you, Rob! Your explanation is very clear and very helpful. You mention the possibility of White's marketing an MXT with a 10.25" coil. Are you privy to information revealed by a highly-placed source who spoke only on condition of anonymity?
Thanks for the offer to sell the 6x10 but, frankly, from what I'm gleaning from the ongoing (I hope) conversations here about coils for the MXT, I'm now leaning toward emulating you and using a 10" EX (or a 10x12 SEF?) in lieu of a 6x10. I suppose the round or butterfly shapes would be more difficult to manoeuver in tight spaces than the oval 6x10, but I do intend to buy a 4x6 shooter.
Rob, you said above, "I think if they answer your post several of the regular people on this forum no longer use their 6x10 coil. I know on some forums I hear they use no other coil." Do you mean no other coil than the 6x10? or the 10" EX?

I am a firm believer in the 6 X 10 DD, its one great coil it just doesn't get the depth as some of the others. But you can't beat it when your in trashy yards or high mineral ground, that's the only coil I will use when prospecting.
They use the 6x10, which probably is the coil used by MXT users more than any other coil. As Bob said it gets good separation and coverage but is not the deepest coil. The 6x10 is also more resistant to EMI than many coils when used on the MXT. Not everyone likes the same coil. Many guys never take the 5.3 coil off their detector. Depth is not their main concern. Coils are a matter of preference and hunting style. Rob

Well, I intend to hunt coins and jewelry, but I'm particularly interested in gold nugget hunting in some of our arroyos. I know the 6x10 DD has often been recommended for nugget hunting, but I'm wondering if the 10" EX or the 10x12 SEF are likely to out-perform the 6x10 on nuggets. Anyone have an opinion

I been told that the 10 X 12 SEF does real good in highly mineral soils that are common to gold bearing areas, BUT you have to take in consideration the shape of the thing it's going to be hard to work a coil like that around rocks and brush. Now I use the 6 X 10 DD when prospecting because of the shape and it gets around obstacles and works extra good in mineral soils, And you don't really need great depth in the gold Fields because most gold areas have a shallow soil over bedrock. Also the MXT will not pick up small gold any deeper then 3 to 4 inches anyway, bigger nuggets will ring out with any coil. So I have been prospecting for gold for over 20 years, if you want my opinion I would say the 6 X 10 DD is the best combination for the MXT and gold hunting. The Whites GMT is one of the best gold machines out there and it comes with a 6 X 10 DD coil on it I also own one of them. I do use my MXT more now when prospecting because the three mode settings come in handy. But I have said this before the MXT + 6 x 10 DD = GMT

Gold I have found this year in Arizona with MXT and 6 X 10 DD coil and some are pretty small

Yes, you can find gold in your area or at least in a county or two away from you.
Placer gold can be found:
Sandoval County; area gravel deposits, near Placitas.
San Miguel County; the Willow Creek Mining District, just east of Terrero.
Santa Fe County; all area washes, arroyos and slope gravels {generally dry} along the northern, western and southern slopes of the San Pedro Mountains, including Tuerto Creek and Larzarus Gulch, in the Golden area; area dry washes, arroyos and slope gravels in the Ortiz Mountains, between the San Pedro Mountains and the Cerrillos Hills, near Cerrillos.
But you can find placer gold in almost every county, you just have to look for those areas a little harder. Always remember gold is were you find it!
Did they ever get all that road construction done out there on I 40 came throw there this past July, MAN it was a mess.

Thank you, Bob. It seems to me you must have given me that info before. Looks awfully familiar. In any event, a very quick check against the pamphlet I bought suggests it includes the areas you mention. As for I-40, forget it. One stretch or another through town is always under construction.
