The pedestal mount from Fish Finder Mounts .com comes with 2x 6.5" shaft links equalling 13" inches of total rise height. You can mount one fish finder screen at the top of the pole or you may select a single or multiple additional Adjustable Swivel & Tilt Arms to mount your finder control screen at variable detents up and down the pedestal shaft/pole.
NOTE: If you are mounting more than one control screen, make sure you add more mounting swivel plates corresponding to the number of screens you will have mounted. More swivel mounting plates can be added by purchasing them at these following links:
