We have been using the Eartec radios. They have worked well for us. The admiral can even hear me talk when in the engine room while underway. I don't find the headsets that came with the package very comfortable to wear, but we only have them on when manuvering in close quarters or for other quick jobs. My sight line from the pilothouse is not good astern, and the radios really cut down on raised voices while trying to keep up with sitautional awareness.
