One of the best user manuals I have ever used for an electronic device! A great piece of kit.

What Customers Are Saying About the AISWatchMate...
The WatchMate was a godsend when I recently spent two days, single handed, in the shipping lane leading into the Malacca Strait. At one time I had over 30 targets, some doing nearly 30 knots! You are welcome to use my comments on your website. I tell everyone how important a piece of safety gear the WatchMate is.

I'm a regular crew for the owner and always help out on the upkeep and new toys. He chose the WatchMate 850 based on the fact that it was one of the few approved for use here in the US, the fact that it had it's own display, and that with it's own GPS, it could act as a redundant GPS source.
I don't think he or I had any idea it would be as useful as we have learned at helping to integrate NMEA on the boat, and then output that in an easy to use format. This has been a pleasant surprise. The boat is a 40' sailboat that is based between Maryland and Maine throughout the summer. We're excited to have the additional information provided by the AIS WatchMate to increase the level of prudent & safe navigation, whether delivering or racing.
Again, I can't say thanks enough for the great product with so many intelligent features built in as standard. And more importantly, thanks for the amazing support and customer service. Your company and products will get nothing less than the highest recommendation from me by anyone who asks about AIS.

We just installed the new software update with the Anchor Watch feature. It is fantastic!! That feature alone should make anyone buying an AIS system, choose Vesper Marine. From a full time cruiser, you have created the ideal anchor watch system. Thanks!
