RapidFix™ truly lives up to its name as the fastest self-locating beacon in the world, providing accurate emergency position data
to Search and Rescue satellites within minutes instead of hours!

DISCONTINUED

Optically interfaced with a vessel's GPS receiver, the RapidFix continuously updates and stores precise position data. When activated, "Instant-ON-GPS" technology immediately transmits coordinates to Cospas-Sarsat satellites along with a registered, digitally coded 406 MHz distress signal. A 121.5 MHz homing signal is activated and, with the RapidFix's incredible GPS position accuracy, the search area is reduced to several hundred yards instead of a general two-mile radius.

  • NEW FEATURES: Send I'm OK Messages. Increase the functionality of your beacon with optional 406Link.com non-emergency messaging service.
  • GPS interface-optical data interface via infrared diode (NMEA 0183): Flashing LED in GPS interface confirms data transmission from GPS; downloaded GPS coordinates confirmed by flashing LEDs within three seconds of completing self-test sequence
  • Patented proprietary electronics package for faster, more stable 406 frequency transmission; full functional self-test including battery voltage and internal circuitry
  • Fully enclosed, high density, UV stabilized polyethylene bracket hydrostatic release
  • Automatically deploys EPIRB if vessel sinks to approximately 13 feet (4 m)
  • Fastest means available of delivering GPS position
  • Field programmable - built-in vessel code can be reprogrammed by an ACR Authorized Service Center worldwide (Maritime/Serialized/Radio Call Sign/MID Protocols, Country Code, etc.)
  • Lanyard coil retained with all around cover for non-tangling deployment
  • Universal usage illustrations; English and French languages
  • 406 MHz EPIRB meets all regulations and is fully approved worldwide
  • Built-in strobe for enhanced location in poor visibility conditions
  • Single, three-position switch for easy test and operation. Steady green LED indicates unit has passed full functional test, flashing red LED indicates unit is "ON"
  • Transmits on 406 MHz (Cospas-Sarsat) with your registered, digitally-coded distress signal, and 121.5 MHz (SAR homing frequency)
  • Can be manually activated; self-buoyant - no external float collar to lose
