I purchased one and installed it last May on the starboard stern on a 9 foot pole.
Installation took about 10 hours (one Saturday), which included finding a welder to attach the mounting plate to the pole. I used it for an
offshore return sail from FL to NC after wintering in the
Bahamas.
It was a natural extension of what I've been doing. I use 2 IPads for
navigation and
AIS, which is transmitted over
WiFi on the
boat. I purchased the
navigation application that allows the
radar plot to be overlayed over the the NOAA
charts, very handy for finding nav targets.
I was
single handing and found it indispensable
offshore, especially the alarming functions. I also used it in the
ICW during blinding rain.
I can highly recommend it.
