Hey guys just wanted to know your oppinions on the ctx and some usefull settings one for cellar hole high iron sites, one for saltwater beaches,one for farm fields with maximum depth and one more for trashy parks with deep silver. Any info on settings and comments on the machine would be much appreciated... I'm currently running an F75 with NEL coils... I want to hit the ground running and not spend too much time on playing with settings when I get it.
