When you are heading out on the water, the Cobra Fixed Mount VHF Marine Radio with GPS is vital for communication and safety. The built-in GPS receiver instantly pinpoints your location to make sure others are able to see your exact location incase of an emergency, and the 24 hour access to all NOAA weather channels allows you to dictate your travels according to the weather. This radio can also be fully submerged in water and remain usable, just incase you get caught in a storm, and the Rewind-Say-Again feature helps you make sure you are able to hear incoming VHF calls repeated again if you didn't hear them accurately the first time.
