What singe coil for MXT would be good for Coinshooting and nugget hunting?

I need to pickup a small eclipse or an excelerator for coinshooting but, What coil could I use for coinshooting and gold? Maybe one of those 4x6 coils?
 
I love that little 4X6 coil for coin shooting the areas where you want good separation, my wife and myself have picked some nice coins out of area other have been and been to trashy. Our main coil is the 6X10 DD coil of Whites which also is one great coil.
Never used a Excellerator coil as I have been more than happy with the 4X6 and the 6X10 Eclipse coils for depth and target ID.
 
with the 6x10 DD from Whites as your first accessory coil especially if nugget hunting is part of the mix. That said, for coin hunting I prefer round DD coils over ellipticals because they tend to give a better response on tilted and deeper coins.

EXcelerator coil. No doubt about it!

As Tom mentioned, I usually prefer a round coil for most coin hunting applications, especially concentric to hit better on canted coins ... unless the DD configuration provides a good, more open field ... and my #1 pick for most coin hunting in lower-to-moderate trash would be the 8" DD EXcelerator coil. For trashier sites, bushwhacking, or nugget hunting applications, the 4
 
Thanks for the input. I might pickup something this weekend if my wallet is heavy enough. :)
 
Definitely the 6x10 Eclipse coil. I live in Gold country and coin shoot also. Nothing wrong with the stock coil, but in trashy areas it will drive you crazy. I own every Whites coil for the MXT and one of Jimmy Sierra's the 12" hot shot. If you buy an after market coil go with Jimmy Sierra's the Excellerators are C&@p in my opinion
 
John MXT/DFX,
I also, need to get a smaller coil for the high trash areas. I have read many positive comments about the 5" Excellorator and the 4.5 X 7 and the whites 5.3 Eclipse. can you be more specific about why you think the Excellerators are C&@p. And what you really like about the whites or Jimmy Sierra's.

Thanks
Mike
 
For a small coil I prefer the Eclipse 4x6 DD over the Whites 5.3" coil. Much more stable and less noisy, depth is about the same. Jimmy Sierra's Hot Shot coil covers alot of ground, is lite weight and is very sensitive on small objects especially gold. The Deep scan 1400 gets great depth but not as sensitive as the Hot Shot on small items, it is great on really hot ground but is not very good on pinpointing. As far as the Excellerators I have had three 14" coils, one 8" coil and one 5" coil. The first two 14" coils were defective the third one was noisy got no better depth than the stock coil and sensitivity past 10 or +1 was not possible, it did cover alot of ground. The 8" coil was ok, probably their best, got a little less depth than the stock coil but not more than the 4x6 Eclipse. The 5" was ok very similar to the 4x6 Eclipse but was a little more noisy in hot ground. Overall quality of the Excellerator are not near Whites or Jimmy Sierra's. I am not sure were they are built but the quality is just not there in my opinion. I am not trying to bad mouth the Excellerators, but I wish Kellyco would improve them, they are a great idea with lots of potential they just need to go back to the drawing board especially the 14" coil.
 
Thanks John MXT/DFX, your opinion considering the Excellerators seems pretty logical based on your experience with the products you mentioned.
I have an MXT with the stock coil and a 1400 DD that is nice but not real comfortable to use and I'm not real good at pin pointing with it yet. The stock coil is driving me crazy especially at some of the older baseball fields with the all the junk,tabs, screw tops, foil,etc.
I have been able to have great luck coin shooting with the stock 950 coil, but I now want to really make an effort going for rings and I feel I can go over the sites I've already searched and concentrate on jewelry so, I'm really looking for a smaller coil. I was hoping to find one as accurate in depth indication and target acquisition as the stock coil. I agree, I also think whites coils are made very high quality. I just might pick up the 5.3 but, it is concentric and I kinda have my mind made up on a the DD format. Thanks again, good info.
 
I just picked up a 5.3 (on sale)and I wish I had gotten the 4x6. Hopefully I will be testing it out sunday.
 
My opinion is to go with the 4x6 DD over the 5.3 coil. The 4x6 will get the same depth as the 5.3 and is quiet and very stable. I see no advantage in the 5.3" over te 4x6 DD. Their are advantages in the 4x6 DD over the 5.3" such as finding small items especially gold nuggets in hot ground. For coin shooting I still prefer the Stock coil and in trashy area I will use the 6x10 DD and the 4x6 DD. The one coil I want to try is the Jimmy Sierra Bigfoot, I think that will be my next coil.

I don't know why you think you should have bought the 3+x6+ when you bought the 6
 
Because I was shown how the DD coils have better coverage, at least thats how I understood it. I was told that regular coils project a conical shape field but the DD project a flatter, wider field that covers more area, Is that not the case?
 
this is only my opinion and shared by a few others. The wider coverage of the DD coils does not extend to their full depth nor does it have an advantage on shallow targets over concentrics. It is in the mid range depths (where most targets tend to be) that they have an advantage.

Concentric coils are mistakenly shown as having a cone shape pattern, it is actually more bowl shaped. Neither coil design has much of an advantage over the other when it comes to fringe depth targets. You need to use lots of overlap to maximize depth irregardless of the design and don't forget, generally speaking it takes a 10" DD to acheive the same depth/ response that an 8" concentric will give.

These graphs from ML's web site show a comparison on DD vs Concentric deigns. These are large elliptical coils for their gold detector series but illustrate the difference in coil design quite well.

Great visual, Now I can see why the DD design is more forgiving in high trash sites, but if the trash is very close to the surface it doesn't matter what format.
Thanks
