Hi Rick, I chose the 5" DD because I intend to do some prospecting with my F75.
Most goldfields are heavily mineralised, and DD "widescan" coils are much quieter when the mineralisation is high.
Also I like DD coils, IMHO they are better at target separation than the concentrics
I appreciate the great pinpointing ability of the concentrics when coin hunting,
but target isolation amongst iron, and prospecting capability are the most important requirement for me right now.
