The plate contains different combinations of pre-drilled holes which will match up to many electronic devices and mounts, including Marine GPS, CB Radios, Ham Radios, Gimbal Brackets and more. The rubber ball and socket technology dampens shock and vibration, as well as allowing for almost infinite adjustment and perfect viewing angles.
