Drastically increase your probability of survival at sea with the multiple built-in redundancies of the GlobalFIX V4 marine distress EPIRB. Upon activation, the GlobalFIX V4’s robust internal GPS accurately fixes your exact location. Your coordinates are then broadcast via a powerful 406 MHz distress signal to Search and Rescue forces worldwide. In the absence of GPS data, orbiting Cospas-Sarsat satellites can accurately triangulate your position using the 406 MHz signal alone. A 121.5 MHz homing signal further guides searchers to your exact position. The GlobalFIX V4 is a full-featured EPIRB loaded with high-efficiency electronics for performance you can count on, including an internal 66 channel GPS for faster acquisition from a cold start. A protective keypad cover helps prevent false activation, and the all-new, user-replaceable battery pack has a 10-year replacement interval — reducing the overall ownership cost and making replacement a breeze. Registering your EPIRB is mandatory in most countries. Registering is very important because should your beacon ever be activated, it is how Search and Rescue Teams will know who you are, and contacts provided may be able to supply information about your specific travel plans. In the absence of this information, it may take longer for a search-and-rescue operation to begin. Please note that this EPIRB must be registered in same country as the MMSI registered to your vessel. For US registered vessels, please choose our “Programmed for US” listing. For registration outside the US, please chose our ‘Programmed for Rest of World’ listing and advise us of your required country of registration after purchase so we can program the device for you.
