Raymarine Ray53 VHF Radio Integrated GPS Receiver
Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The Ray53 packs a built-in 72-channel GPS receiver into Raymarine's compact VHF chassis, giving you accurate position data for Class D DSC distress alerting straight out of the box, with no external GPS antenna required. It transmits at a selectable 1W or 25W across all US, International and Canadian VHF marine bands.
The internal GNSS engine tracks GPS, GLONASS and Beidou with SBAS support (WAAS, EGNOS, MSAS) for accuracy of better than 5 metres with SBAS. An external passive antenna can be connected via the TNC port where a clearer sky view is needed. Built to IPX6 and IPX7, the Ray53 suits exposed helm and flybridge installations. Connect SeaTalkng / NMEA 2000 to a compatible Raymarine multifunction display to share DSC and position across the network; NMEA 0183 and an audio (RCA) output complete the connections.
