Even after reading the article I am a little confused about exactly what this alarm does. Does it transmit GPS co-ordiantes? if so to what? If this really gives a DSC alarm with GPS co-ordiantes, which show up on the recieving VHF radio/and or chart chart plotter, properly hooked up, then it is a great device. If only a unique short range DSC, not quite as useful.
It is expensive, and you can buy 3 EPRIB's for the same price. A VHF RDF is expensive, and not readily available on most boats. There are much cheaper alerts for MOB.
But with GPS and DSC--it would be a real life saver. The best application would be offshore sailboat racing--or short hand cruising. These are situations where man overboard happen fairly frequently, and would be the best market. But with a 10 man crew--this would mean about $7500 for just the units!
