f2 depth

[Fieldodreams74]

Greetings all. I have an f2 and regularly find a coins up to 4, somtimes 5 inches. I am using the coil
that came with it. Is there a different coil I can put on to get more depth, and how much could I gain?
Do machines that ground balance generally get deeper penetration?

Thanks
Jahson

What coil came with it?

11"DD is about the best your going to get, which by the way is an excellent coil for depth and target separation.

4"- 6" is about where your going to find 90% of coins regardless of machine or coil used.
