When you’re setting out on a boat adventure, it’s important to have safety equipment you can count on. Designed with high-efficiency electronics that are built for performance, the GlobalFIX™ V4 GP Emergency Position-Indicating Radio Beacon or EPIRB provides the protection you can trust in an emergency situation. Should the unexpected happen, this EPIRB will relay your location to a vast network of search and rescue satellites, allowing local first responders to get you home more easily.

GlobalFIX V4 Radio Beacon Features

The GlobalFIX™ V4 emergency beacon 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.

The GlobalFIX™ V4 has two functional self-tests to monitor the beacon’s transmission, power and battery performance and GPS acquisition. Pair these tests with ACR’s optional testing portal (available for the Americas only) and receive satellite confirmation messages directly to your cell phone or email.
