Smaller coil, better separation less depth. Larger coil covers more ground and gets deeper.

some guys swear by the 5'' DD coil. I have not used one yet. I guess it depends on what you want to hunt for. DD coils are good in trashy areas as far as seperating targets. I just got my F5 so I have not looked into coils for it yet. Like Bart said, the bigger coils can give you better depth and will help you cover more ground faster. I know this is not much help Jamton but its bout all I got
Hi there 
I just have to reply to this as I have had an eye opener this season. I have the F5 with stock, 11" DD and 5" DD coils. Last season I swore by the 11" to be the best coil for this detector. Come this season and my new 5" coil which totally changed my views on "bigger is better". The site has to be, in my opinion, really clean in order for the 11" coil to work efficiently. Even on semi-trashy areas you are missing lots of goodies because there are good and bad items under the coil at the same time causing the signals to be difficult to interpret.
I got a really good lesson on this one this autumn when I found a site that has lots and lots of coins. I scored over 300 euros (400+ USD) there in just 14 outings. I started out as usual with my 11" coil and while I thought that I did well with 10-15 euros per session for a few outings I was far from realizing the full potential of that site. Once I switched to the 5" coil my session totals really jumped. I started to get 25-35 euros per session (about three hours each) and at the same time the am

The stock coil is an exceptional coil design. You can get close to metal like it was a small coil, and it provides better ground coverage at depth than a standard round concentric and better target id. Good sensitivity to small low conductors.
The 11" DD is deeper, provides better ground coverage, looses some sensitivity to small low conductors. works well, but....it changes the balance of the unit and wears on the arm.
The 5" DD will go deeper than the stock coil in mineralized ground, provides exceptional separation and pinpointing, very good sensitivity to small low conductors, and can get close to other metal objects, but lacks ground coverage.
The 5x10" DD goes just as deep in the minerals as the 5"DD, still provides very good target separation, still maintains very good sensitivity to small low conductors and better ground coverage. However it cannot be used close to above ground metal objects like poles, barrels, etc.

Jamtom: Depends on where you are hunting and what you are hunting for. If you are hunting parks, lots, or school yards the 5 inch DD will quickly pay for its self, if you are hunting coins and jewelry, will occasionally be helpful if hunting relics. HH Steve
