Finally got around to wiring up my Garmin to an Easy AIS. Easy AIS was recommended to me by Garmin at the boat show rather than the NASA one due to quality and ease of setting up. After a bit of faffing around because Garmin and Easy AIS use different terminology for NEMA wires, it was plug and play. How sensitive is it, well with the range set at 0.5 miles the alarm goes off everytime the Gosport ferry crosses the harbour. What did suprise me is the number of small boats and yachts transmitting AIS.
How useful is it? well for a rib wandering around the Solent, it's only
a "nice to have" and you won't want the alarm turned on or it will be constantly activating. However on the yacht for cross channel trips knowing were and how far away the big boys are is definately worth while.
Btw, had the chance to look at the NASA AIS at the boatshow. It's tiny, the screen is about the size of a fag packet (cigarettes for our colonial friends) black / white display and not waterproof according to there website.
