hey Starman2 i believe the only real difference of those two coils are these...
depth and separation and maybe stability .let me explain , the d2 is a bigger coil and i'm pretty sure it will get you more depth than the 6x10 . how much more :thinkingabout: :thinkingabout: well thats probably up for debate , the 6x10 i'm sure has better separation. again you will get those that want to debate how much better. stability is usually better with smaller coils over larger ones and you can often crank sensitivity higher with smaller coils over the larger type. i think it lies with more of a personal preference than anything at all , i almost all the time have the 6x10 on my dfx . i love that coil for the type of detecting i do (colonial cellar relic and coin detecting) it gives me about the best separation from a bigger type coil so i can still get very close to a trashy cellar like a smaller coil
but also cover a good amount of ground like a larger one . i hope this sheds some light on the two. your other question i assume you mean the signature area at the bottom of your post page ?? i believe that this space is limited to the number of characters you can use and you might have to experiment with it ,if i didn't mis-understand
your second question . please pm me or any of the Moderators to explain more.
