The Ocean Signal SafeSea EPIRB3 Pro is a full-featured 406 MHz global rescue beacon with an auto-release float-free bracket that packs a host of features into a compact modern design including AIS technology. AIS provides local rescuers with precise and reliable information on the current beacon position, thereby speeding rescue operations. Additionally Return Link Service (RLS) comforts those who activate the beacon by confirming that their distress message has been received. The inclusion of Near Field Communication (NFC) capability allows the use of a smartphone app to monitor the EPIRB's battery and other functions ensuring it is working properly. The EPIRB3 Pro comes complete with a Category 1 auto-release float-free mounting bracket. This bracket securely stores the EPIRB3 Pro for the duration of your trip regardless of the conditions experienced throughout. It also provides the best chance of deployment in distress situations where it is difficult for a crew member to reach the EPIRB.• No subscription required• 406 MHz Cospas Sarsat Distress Signal (MEOSAR Compatible)• 121.5 MHz Local Homing Signal• AIS (Automatic Identification System) Alert• Smartphone connectivity via NFC (Near Field Communication)• Free Ocean Signal Beacon Mobile App• RLS (Return Link Service) Functionality• GPS / Galileo / Glonass GNSS• Global Coverage• Category 1 auto-release float bracket included• Small and lightweightTechnical SpecificationsStrobe: White and infraredDimensions (without antenna): 6.8" x 3.6" x 3.1"Weight: 0.42 lbs.
