Ocean Signal SafeSea EPIRB3 Cat I with AIS and RLS

The Ocean Signal SafeSea EPIRB3 Cat I with AIS and RLS is the modern mariner's lifeline when the unexpected strikes far from shore. Whether you're running a commercial fishing operation, cruising offshore, or working in remote coastal waters, this Emergency Position Indicating Radio Beacon represents the gold standard in maritime distress technology. Built to international Category I specifications, it delivers the rapid location capability and multi-channel alerting that rescue coordinators depend on when every minute counts.

The EPIRB3 combines three critical rescue functions into one compact unit weighing just 3.42 pounds. The integrated Automatic Identification System (AIS) broadcast ensures that nearby vessels receive your position on their electronic chart displays in real time, while the Rescue Locator Signal (RLS) and traditional 406 MHz distress beacon activation provide multiple layers of location redundancy. When manually activated or triggered by hydrostatic release, the device transmits your vessel's registered information directly to global search and rescue networks, bypassing any delay in human voice communication. The Category I rating means it performs reliably in the harsh marine environment—salt spray, extreme temperature swings, and rough handling included.

This EPIRB is the right choice for any vessel operating beyond visual range of coastal rescue assets, from commercial fishing boats and offshore yachts to research vessels and remote work platforms. The RLS feature adds survival advantage by alerting nearby ships immediately through standard maritime alerts, while AIS transmission ensures constant position updates on vessels within radio range. Professional mariners and serious cruising boaters recognize that a dedicated, regularly serviced EPIRB is non-negotiable safety equipment—not optional. Installation requires no special tools; simply mount it in an accessible, unobstructed location above the waterline and register the unit with the appropriate maritime authority to ensure your vessel information is linked to the beacon code.
