Know before you buy
Yes. It is constructed from powder-coated marine-grade aluminum, which is specifically designed to resist corrosion and degradation in harsh marine environments.
The 1.5-inch rubber ball acts as a dampener, absorbing the energy from engine vibrations and choppy water before it reaches your device. This helps protect sensitive electronics and keeps your screen steady for easier viewing.
Absolutely. The double socket arm design allows for near-infinite adjustability, letting you tilt, swivel, and rotate your device to achieve the perfect viewing angle.
The plate features a pre-drilled hole pattern designed to accommodate a wide variety of GPS units and radios. However, if your device's mounting holes do not align, you may need to drill additional holes into the aluminum plate to create a custom fit.
Yes, this mount is compatible with RAM Pin-Lock Security Nuts. These replace the standard knobs on the socket arm, requiring a specific key to loosen the mount and remove your device.
Because this is a screw-in mount, you will need a drill and appropriate mounting hardware to secure the 2.5-inch round base to your desired surface. Please ensure the mounting surface is sturdy enough to support the weight of the mount and your electronics.
