I use a set up from Revolution marine. they are a basic set, no radio or cell phone interface, just a way of communicating with others on board. I didnt like the throat mic so I got regular mics on stems.
The problem I had with them was extreme wind noise. At first I thought they sucked. Then I took off the wind sock to take a look at the mic. I couldnt believe my eyes!! The mic had holes to allow sound in, not only facing your mouth but facing forward, into the wind. WTF!! A small piece of electrical tape over the holes fixed the problem. I dont know what the hell they were thinking
