The MX300 is a well engineered and fully featured 3/1 Watt Switchable VHF Marine radio, and is an essential part of your safety kit on the water. The perfect solution for small watercraft such as tinnies, kayaks and jet skis that may not have electrical systems or sufficient space for a fixed-mount radio. Built tough to withstand the harshest marine environments, the MX300 is waterproof to IPX7† if dropped overboard and will float to ensure easy retrieval. †AC Adaptor is not waterproof.
