Hi Guys,

Looking at the sef coils for the beach using all metal or mixed mode in 22.5 frequency. This will be at the back of the beach to the towel line. How much more depth on a u.s. dime with the 10 dd against the larger sef coils.

I want the best depth not worried about the coverage so much. We do have a dealer here in Australia for deteck coils but they have no idea of what extra depth you can get.

Regards Pinpointa.
