put on my new 6x10 dd coil, & first thing i noticed was could not run gain more than 8 , or will overload , & after run awhile could turn up to 9.5 & no more , it found clad & targets deeper than my 4x6, & my question is can you turn up gain to +2 or 3 , & not over load my soil is 34 -56 , mild, & any other tips on 6x10, thanks hh.
