With the introduction of Return Link Service (RLS) technology and Near Field Communication (NFC) capabilities, the EPIRB2 provides significant advantages over its predecessors. Return Link Service EPIRBs comfort those who activate the beacon by confirming that their distress message has been received and the inclusion of NFC capability allows the use of a smartphone app to monitor the EPIRB’s battery and other functions ensuring it is working properly. The innovative new features of the EPIRB2 make it an excellent choice for a wide variety of marine applications specific to both recreational and commercial vessels.

In developing the EPIRB2, Ocean Signal has drawn on its substantial experience in designing and producing high-quality, feature-packed Return Link Service EPIRBs utilizing a conveniently compact form factor. Employing multiple levels of integrated signalling technology, including 406 MHz, GNSS (GPS, Galileo, Glonass) positioning, and a 121.5 MHz homing signal, the EPIRB2 effortlessly guides search and rescue forces to your location. The addition of Return Link Service (RLS) technology and Near Field Communication capability round out the impressive feature set of the EPIRB2.


Smartphone Connectivity utilising Near Field Communication (NFC)


The integration of NFC technology provides users with the ability to conveniently access beacon data from their mobile phones. Simply placing a phone near the beacon automatically opens the Ocean Signal Product App and provides access to a wealth of usage data including current battery life, the number of self-tests completed, the number of GNSS tests completed, and, if applicable, the amount of time that the beacon has been activated.


Detailed information on each self-test and GNSS test performed by the beacon is also available. Information that is accessible for each successful GNSS test includes access to a map showing exactly where the test was performed, the date and time of the test, the time it took the beacon to get a GNSS coordinate fix, the number of satellites the beacon used to obtain that fix, and the accuracy of the location.


Global Coverage via the Cospas-Sarsat Satellite Network


Harnessing the global reach of the Cospas-Sarsat Satellite Network, the EPIRB2 can be activated anywhere, at any time, and will transmit your 406 MHz distress message. The distress transmission includes beacon coordinates that are derived from the EPIRB’s integrated GNSS receiver and are accurate to within 100 meters.


RLS provides reassurance for users by sending a return signal through the Galileo satellite network directly back to the beacon to confirm that the distress message has been received and the beacon location has been detected. User confirmation is distinctly indicated by a flashing blue light.


Return Link Service (RLS)


The inherent stress associated with a maritime emergency situation is a challenging symptom that all boaters unfortunately have to confront should they find themselves in a distress scenario. Fortunately, the inclusion of the RLS feature in the EPIRB2 provides a means of minimizing the stress in such situations. Return Link Service EPIRBs provide direct-to-beacon confirmation letting the user know that their distress message has been received and their location detected. The indication of RLS functionality is represented by a distinctive blue light, making it easy for users to ascertain exactly when the RLS confirmation is received.


Ocean Signal prides itself on continuing to offer new and exciting features such as RLS and NFC as it maintains its goal of offering the highest quality innovative safety products. Regardless of the reason for your next voyage, or your chosen destination, guarantee your safety with the carriage of the EPIRB2.
