I have a 6"swing arm base and 2 ram ball mounts raising mine some but I need to get a straight 12" or 18" extension rod to raise it more. The swing arm mount is awesome for gaining room wherever you need it (any direction that is). I fish both sides of the boat and use either foot on the moveable trolling motor foot pedal so the 1 foot 360* variance of the swing arm and the 2 ram mounts put the unit level and in front of me no matter which way I am facing.
