Brand new, highly accurate, totally waterproof Marine GPS receiver / Smart antenna.
For use with any NMEA device. Includes marine radios such as Navman 7100 etc.
These receivers are NMEA and not Sea Talk. Some Raymarine devices are Sea Talk only and some are both. Check your owner’s manual before buying.
You will not be able to buy a Marine standard GPS receiver of this quality anywhere for a better price than this. I guarantee it!
This receiver, the SA 320, is of a higher standard and quality than the Raymarine 125 which costs £250 or thereabouts.
Connect this to your radio and when you send an SOS it will automatically send your position to the Coastguard.
Drop it and it will not break, totally waterproof, nothing affects it, and I mean NOTHING, Radar, VHF, not even the Earth's magnetic field, Nothing.
You sail to Spain and you will still be within 3 metres! Sail around the globe and it will still be accurate to 3 metres. Not like the road navigation receivers which the mapping software helps to keep on the road its meant to be on!

You will find others on ebay promoting their 'marine standard USB ' receivers, but be warned they will not have the accuracy and protection that this offers. The small wired receivers you find on ebay are not meant for marine use, when wet they will fail, possibly leaving you stranded. When sending an SOS, the VHF transmission will cause them to show a wrong or no position
This is a totally marine quality GPS receiver / Smart antenna.
It is protected from all kinds of interference possible at sea.
