Blimey! Well, my 2 units are both combo, so I guess I have 2 of each! Fixed and handheld VHF, I think there is a compass in grab bag too. Phone and PLB beacon. I think the plb works on a different sat system for Comms, but it does require gps to send location, but I think.can be tracked once help is close. Just a note, prob one of the smallest boats in the club! R
