Ocean Signal SafeSea EPIRB3 Pro (Cat1)

The Ocean Signal SafeSea EPIRB3 Pro (Cat 1) brings together global satellite distress alerting, local AIS positioning and automatic deployment in one advanced Emergency Position Indicating Radio Beacon.

Designed for commercial, offshore and serious recreational vessels, the EPIRB3 Pro is supplied with a Category 1 automatic-release float-free housing. If the vessel sinks, the housing is designed to release the beacon automatically, allowing it to float free and activate once in the water.

That means an emergency distress alert can still be transmitted even if the crew is unable to manually reach or activate the beacon.

Global 406 MHz Distress Alerting

When activated, the EPIRB3 Pro sends a powerful 406 MHz digital distress signal through the international Cospas-Sarsat Search & Rescue satellite system.

The alert includes the beacon's unique identification and precise GNSS position, helping Rescue Coordination Centres identify the vessel and determine where assistance is required.

With global Cospas-Sarsat coverage, the EPIRB3 Pro provides a dedicated emergency communications link far beyond conventional mobile or VHF coverage.

AIS for Faster Local Rescue

Alongside the global 406 MHz distress transmission, the EPIRB3 Pro also broadcasts an AIS emergency signal locally.

Compatible AIS-equipped vessels in the surrounding area can see the EPIRB's position on their navigation displays, providing rescuers nearby with an immediate and precise target to navigate towards.

This combination of global satellite alerting and local AIS visibility can help reduce the time it takes for rescuers to locate survivors.

Return Link Service – Know Your Alert Has Been Received

Once the Cospas-Sarsat system has successfully received and localised your distress alert, a return signal can be transmitted back to the beacon through the Galileo satellite network.

A visual indication confirms that the distress alert has been received and forwarded through the Search & Rescue system, providing valuable reassurance in an emergency.

RLS does not provide two-way messaging or confirm when rescuers will arrive, but it lets you know that your emergency transmission has successfully reached the system.

Multiple Ways to Help Rescuers Find You

The EPIRB3 Pro uses several complementary technologies to improve the chances of rapid location.

Integrated GPS, Galileo and GLONASS GNSS positioning provides accurate coordinates, while a 121.5 MHz homing transmitter helps Search & Rescue teams locate the beacon during the final approach.

High-intensity visible and infrared strobes provide an additional visual signal at night and in poor visibility, giving rescue crews another way to identify your location.

Category 1 Automatic Release Housing

If a vessel sinks, the hydrostatic release mechanism allows the EPIRB to automatically deploy from its housing at approximately 1.5 to 3 metres depth. Once released and in contact with the water, the beacon can activate automatically.

The EPIRB can also be removed from the housing and activated manually whenever required.

This automatic-release capability makes the EPIRB3 Pro particularly suitable for commercial vessels, offshore sailing and SOLAS applications where float-free emergency equipment may be required.

NFC Smartphone Connectivity

Simply tap a compatible smartphone against the EPIRB and use the free Ocean Signal app to access information such as battery status, self-test history and beacon programming details.

Because NFC doesn't rely on the EPIRB's emergency battery for communication, you can check your beacon without compromising its standby readiness.

10-Year Battery Life

The EPIRB3 Pro is designed to remain ready for years at a time. Its lithium battery has a 10-year replacement interval and provides more than 48 hours of emergency operation at -20°C once activated.

That makes it a dependable long-term safety device for vessels operating far from immediate assistance.
