This radio was recommended by a co-worker who is into amateur radio and works around ships. I bought one for use on the water as well, and like the fact that it can take 40 user programmable channels. Note that programming requires a cable and software from Vertex/Standard Horizon. This is readily available and can be done by anyone with computer and radio skills. I like that it is a nice and heavy unit, with great battery life and large display. Unit will use most accessories from the VX-170 2 meter handheld. This includes the programming cable (also used on the VX-7R), microphones and battery packs. The antenna on this radio is short and does not get in the way. Great to have on small pleasure craft or for commercial use. Puts out enough power to be heard and has great audio. It would have got a fifth star from me if it didn't require software and a computer to program. I prefer full DTMF keypads and programming capability. Can't fault the easy to use layout though.

small, lightweight, (for what it packs) this is the top of the line in marine talkies, crystal clear, and ruggard, it charges quickly and looks to be practially indestructible. a great buy!
