ACR GlobalFix V4 – Cat 2 EPIRB


This award winning product is suitable for all vessels but really comes into its own on vessels that are short-handed i.e. Husband and wife sailors.


Survival at sea with the multiple built-in redundancies of the GlobalFix™ V4 Emergency Position Indicating Radio Beacon (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.

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.

A protective keypad cover helps prevent false alarms, and the all-new, user-replaceable battery pack has a 7-year replacement interval.

The GlobalFix™ V4 has two functional self-tests to monitor the beacon’s transmission, power and battery performance, as well as GPS acquisition.

Pair these tests with ACR’s optional testing portal and receive satellite confirmation messages directly to your cell phone or email.
