The adapter serves as a quick release mechanism, allowing you to remove or transfer your Fishfinder in seconds. Designed into the mount is a 1" diameter patented rubber ball and socket system with adjustment points at both socket ends of the arm; this with RAM's rubber ball and socket technology allows for almost infinite adjustment and perfect viewing angles.
