Going to get the AT Pro and was wondering about the optional concentric coil. I just saw a air test with the DD coil. In my area ( Texas) the soil isn't too bad, and from what I have read the concentric does get better depth in less mineralized soil than the DD.
Would the 9X12 coil be better at the Texas beach and larger areas, or should I stick with the DD??
