Hello. i just purchased a new 10" x 14" power dd search coil. it works with my predator 2, anyone out there know how deep i can expect to get hits. just curious. thanks.
My guess would be roughly 12" on typical coin sized targets.
As a general rule of thumb, all things being equal, you can expect about the same depth as a coil is in size. That is to say a 12" concentric coil should get about 12" in depth. The elliptical DD coils get a little less depth, but better ground coverage and separation.
