This fully adjustable universal mount securely holds most chartplotters, GPS, fishfinders and VHF radios while allowing you to reposition the unit for viewing from all angles. The top mounting plate is equipped with 25 hole locations to accommodate virtually any hole pattern. The positive locking head of the Sure-Lok Mount will adjust to any angle by actuating the padded lever. Simply release the lever and move the top plate to the desired angle and close the lever to keep the device from moving. This mount is also adjustable left and right by lifting on the mount and rotating the spring loaded indexing bases.
