Enhance your voyage with the Ocean Signal SafeSea EPIRB3 Cat I with AIS and RLS — a compact, feature-packed 406 MHz emergency beacon engineered for rapid, reliable marine rescue.
Fast, Global distress signaling
When danger strikes, the EPIRB3 Pro immediately transmits a 406 MHz distress signal to the international Cospas-Sarsat satellite network. This ensures rescuers worldwide receive your exact position and beacon identity, enabling a swift response regardless of where you are on the water.
Local rescue acceleration with AIS
In addition to satellite distress signaling, the EPIRB3 Pro transmits AIS data on VHF frequencies as soon as it activates. This local beacon visibility helps nearby AIS-equipped vessels plot your location in real time, speeding on-scene assistance and improving chances of a rapid rescue.
Reliable positioning backed by GNSS
The EPIRB3 Pro uses GNSS (GPS, Galileo, GLONASS) to derive precise location information, delivering accurate position data to rescuers within 100 meters. When combined with AIS and homing signals, this creates a multi-layered approach that helps responders locate you quickly, day or night.
RLS — reassurance when you need it most
Return Link Service (RLS) provides visual confirmation that your distress message has been received by the rescue authorities, offering you peace of mind when seconds count and you must focus on safety.
Smart safety features you can trust
-
Float-free, auto-release bracket: keeps the beacon afloat and readily deployable, even if you’re unresponsive or separated from your vessel.
-
AIS and 121.5 MHz homing: enhances locate-and-rescue capabilities, increasing recovery speed for drifted beacons.
-
Strobe lights (visible/infrared): improves beacon visibility to rescuers in all conditions, day or night.
-
NFC-powered monitoring: use a free smartphone app to check battery health and essential functions before you go offshore, ensuring peak readiness.
-
Compact, ergonomic design: easy to mount on any vessel, from cruising yachts to commercial fleets.
Designed for every mariner
The EPIRB3 Pro is ideal for a wide range of mariners — whether you’re cruising the Med, navigating straights, fishing, working offshore, or sailing beyond the horizon. It combines advanced rescue technology with a streamlined form factor to deliver reliability you can count on when it matters most.
