Ocean Signal safeSEA EPIRB3 Pro Category I AIS GPS EPIRB with RLS & NFC Mobile App, Automatic Float-Free (702S-03933)

The Ocean Signal safeSEA EPIRB3 Pro brings satellite distress signaling, local AIS alerting and modern beacon status monitoring to a Category I float-free installation. Its automatic-release housing supports deployment if the vessel sinks, while Return Link Service, multi-constellation GNSS, NFC mobile diagnostics and visual/infrared strobes add several ways to assist emergency response.

Key Features & Benefits

• Worldwide Satellite Alerting: 406 MHz distress transmissions connect to the Cospas-Sarsat rescue system.
• Integrated AIS Distress Location: Transmits a local AIS alert to nearby suitably equipped vessels as well as global satellite signaling.
• Return Link Service: Provides visible acknowledgement when the rescue network confirms receipt of the alert.
• NFC Smartphone Diagnostics: Use the Ocean Signal mobile app to review beacon information and status.
• Multiple Rescue Cues: 121.5 MHz homing, bright LED and infrared strobes aid closer-range location.
• Long Emergency Readiness: Manufacturer lists 10-year battery replacement and over 48 hours of emergency operation.
• Category I Automatic Housing: Hydrostatic mechanism releases the EPIRB if the housing becomes submerged during a sinking event.
• SOLAS-Oriented Configuration: Pro variant is intended for vessels requiring an automatic-release EPIRB installation.
