THIS IS NOW OBSOLETE AND NO LONGER AVAILABLE             The HX851E is a 'Submersible Floating' 6 Watt portable VHF marine transceiver with built-in GPS and DSC signalling.
The HX851E has DSC (Digital Selective Call) Class D signalling built-in enabling it to participate in the IMO SOLAS GMDSS system and is able to send and receive Distress Calls with accurate position from built-in GPS receiver. All Ships Urgency, Safety, Individual,  Group call with Position Request and Position Report Safety calls are also available.

The built in GPS enables the unit to be used for simple navigation, with storage for 100 alpha-tagged waypoint positions the unit can be  used to navigate to any one of them.

The HX851E is ideal for anyone who sails in coastal waters currently without a VHF DSC radio, or for the 'grab bag' of the sailor or power boater user who is looking for that extra element of safety.

New features include a luminescent gasket strip that glows in the dark, A high power LED strobe light that can be programmed to flash in various configurations including SOS and triggered when the radio falls in the water.

Position and GPS data can be transferred to and from any NMEA 0183 compatible device including Chart plotters using connections in the CD-38 Charger cradle.

The HX851E is CE approved and has been notified for approval for sale in all European countries under the R&TTE directive Annex IV approval process. The Declaration of Conformity can be viewed on this website.

UK users of this radio are required to obtain a Ship Portable Radio Licence with an individual UK MMSI number in the range 02359XXXXX irrespective of whether they already have a Ship Radio licence or not. Users are also required to hold a SRC Short Range Certificate for use of DSC.

Details on how to obtain a Ship Portable Radio Licence can be obtained from the OFCOM website http://licensing.ofcom.org.uk/radiocommunication-licences/ships-radio/ 

Details on RYA Short Range Certificate Course can be obtained from http://www.rya.org.uk/coursestraining/courses/specialist/Pages/SRC.aspx

European Users should check with their local marine regulatory authority in their own country for assistance in obtaining a MMSI number for handheld DSC radio.

Users should be aware that the transmitter power output level of 6W maximum and small handheld aerial means that this device will have a reduced range compared to a standard 25W fixed mount DSC radio with mast head aerial.
