The McMurdo FastFind 220 Personal Locator Beacon (PLB) is a personal safety device designed to alert search and rescue services and allow them to quickly locate you in the event of an emergency, on land or sea. When activated it transmits a coded message on the 406 MHz distress frequency which is monitored by the Cospas-Sarsat satellite system. The alert is then relayed via an earth station to the nearest Rescue Coordination Centre (RCC). As the satellites are in a polar orbit they offer true global coverage - with a PLB you can summon help wherever you are on the planet, no matter how remote.• Standards Cospas-Sarsat T.001/T.007 class2, RTCM 11010.2, ETSI EN 302152-1, AS/NZS 4280.2, NSS-PLB11• Sealing depth Immersion to 10m (30ft) for 5 mins• Operating temperature -20 to +55ºC (-4 to +131ºF)• Storage temperature -30 to +70ºC (-22 to +158ºF)• Altitude 12, 192m (40, 000ft)• Buoyancy Category 2, will not float (keep in buoyancy pouch provided)• Battery type Lithium Manganese• Transmit duration > 24 hours @ -20ºC (-4ºF)• Battery life (storage) 6 years• Battery replacement Service centre• Battery Use Logged by microprocessor• Frequency 406.031 MHz (alert) / 121.5 MHz (homer)• Power 5W (alert) / 50MW (homer) nominal• Unique ID Number Factory or dealer programmed• GNSS Receiver GPS(L1)+GALILEO(E1), 72 channel, ceramic patch antenna• Size (D x W x L) 34 x 47 x 106mm (1.34 x 1.85 x 4.17in)• Weight 152g (5.36oz)• Indicator Light High brightness LED signal light• SOS flash light Morse code SOS flash pattern, 30 operations• Activation Manual, three stage• Self-test Tests transmitters, battery and light Hi-Brightness LED SOS Light Minimum 24 Hr Operation 6 Year Battery | Camping World McMurdo FastFind 220 Personal Locator Beacon (PLB)
