The ACR RapidFix 406 EPIRB has a NMEA-0183 interface which, when used with the included cable, allows a simple connection to your vessel's existing GPS receiver or a dedicated handheld. So long as the RapidFix is interfaced to a working GPS, position information is continuously updated and stored. Accordingly, position data is immediately available upon EPIRB activation with no time delay caused by a cold-booted GPS's initialization process.
Upon activation the RapidFix 406 it transmits on 406 MHz (COSPAS-SARSAT) with your registered, digitally-coded distress signal (which includes the GPS-determined position), and 121.5 MHz (SAR homing frequency). It is available as a fixed-mount Category I model (manual activation / automatic activation once submerged to 13 feet), or the more popular Category II model (manual activation only). There's a built-in strobe light to aid rescue, as well as an easy-to-use switch for testing and operation. A lithium battery with a 5-year replacement life and an 11-year storage life is included. EPIRBs are sold with ACR's 5-year limited warranty and, for safety assurance reasons, are not returnable after purchase.
GPS-enhanced EPIRBs are arguably the greatest electronic rescue products ever! GPS technology now allows EPIRB signals to tell rescuers not only who you are, but also precisely where you are – all in a matter of minutes. Rescue operations will only start after a distress position is determined. Because they quickly relay precise position data, GPS-enhanced EPIRBs save critical time. Compared to standard 406 EPIRB rescue response times which, near the equator, can be hours, the response time following an ACR RapidFix 406 or GlobalFix 406 activation will typically be only minutes. And rescuers can determine your location within a few hundred yards as opposed to a general two-mile radius search area. Replacement EPIRB Antennas available.
