I have one, it is useful but only ok as far as the "execution" goes. No surprise from Raymarine..
My big complaint is that in STBY mode the remote shuts down and then upon start up it needs to reacquire the wireless signal, which takes about 30-45 seconds. This is pathetic!
I bought it to dodge lobster pots and it works well unless you have hit STBY and then try to turn the AP back on via the remote as it takes a little bit of time, too much time.
I have conversed with Raymarine over these flaws and their attitude is typical Raymarine, we are right, you are wrong and most folks want improved battery life.
Well, I for one could care less about battery life I want functionality, batteries are cheap and rechargeable these days. I asked them to do a re-program of mine, was very willing to pay, to add an "always on" setting but they claim they can't... Ya right...
Funny how the next model up has an "always on" function???? Go for the next model up!
Oh yeah the base station simply plugs into an existing Sea-Talk port. Takes longer to install the batteries in the remote than to hook up the base station..
