which DD coil should I buy??

LF for sure if your primary targets are coins. That means you have a choice of two DD coils. Either the Coiltek 6" Digger, or the 15" All Terrain.
If you're hunting where there's significant trash, the Digger is the best option.

Hi from another Ohioan, kgramlich.
I recently made the jump from 80s technology to the 705, along with the 6" LF DD 'Digger' coil. I have been very impressed with that coil so far on several short outings.
I'm in NE Ohio, near the PA border, and the glaciated soil over here has proved to be quite mineralized, generally registering 10-25 at the sites I hunt. The DD coil has done very well; the target separation is excellent and I have found at least a dozen wheat pennies and a couple of indians so far in a very trashy park (an average three foot sweep registers 8+ iron targets) that I've visited often before. Several were on edge too; the coil still hits hard in that case, but the VDI was more narrow and slightly lower, along with more warble in 99-tone mode. After a while you can really start to tell the difference between coins and non-iron trash...although it seems to really like old pull tabs too.
In my own front yard, I've pulled 10 wheats, a 1919 British large penny (what the heck?!), a small cross, and miscellaneous clad that I'd missed for years with my old White's Coinmaster. The 705 is a fun detector and so far the Digger coil is fantastic on finding coins. I'm still waiting to find silver, but I've only had the new detector a couple of weeks and it keeps storming whenever I want to get out! :clsoedeyes:

I primarily hunt for coins and the 6" Coiltek coil is definitely the way to go but just remember that you can work your arm off in a big field using a 6" coil. For the most part, it's not a big deal but the width of coverage is limited. The depth of that coil I would definitely put up against the 10.5" Minelab coils any day.
If you want to cover a larger area then both of the 10.5" Minelab coils are also very good. In theory the MF will be the best for finding sliver but there are a few differences to consider between those two coils. The reaction time of the HF coil is much faster and more forgiving if you are swiping fast with it. The MF takes more time to react and you have to go significantly slower with it in order to get the most out of it. For me, it detects a little deeper in my soil than it's HF counterpart but there is not a night and day difference between the two in my soil. If you ever want to detect at the beach, although not waterproof the HF will do a better on a salt water beach. The 10.5" coils are very close in effectiveness as long as you understand the difference between them and how to use them.
If you wanted to go with a 10.5" Minelab coil and you could get either, used, at a good price, I would pick up whichever you were able to get your hands on. Having all three of those coils and knowing what I know now, I'd start with the 6" Coiltek coil and I'd have a hard time picking one of the 10.5" coils. You'll typically find more coins more quickly with the HF but taking your time with the MF will turn up some older, deeper targets.

I have the 10.5 DD MF waterproof, the 5x10 DD HF not waterproof and the 6" DD digger, new 6" diggers are waterproof don't remember the serial number when they were changed. . Minelab also has a 10.5 DD HF waterproof coil and a 6" DD HF waterproof. I find myself using the 5x10 HF the most just because it is lighter than the 10.5 MF, I also find more nickles with the HF,DD, however I don't feel the 5x10 HF goes quite as deep. I also have the Minelab 9" CC in LF it is very good for copper and silver and in our Nebraska mild soil it gains a little depth over the 10,5 dd. If you are in trash the LF 6" digger is the way to go. I like to cover as much ground as I can so I don't use my 6" all that much. However in an old park and you hit an area of high trash I go get the digger that's where the old coins are still hiding, but not from the digger.
WAIT!! None of the 10.5" DD coils from Minelab for the Xterra are waterproof. Only the 9" Concentric coils and the 6" coils from Minelab are waterproof.ahunter said:
