All this being said, keeping the radio in a fitted dry bag will really help extend it's life.
I second that. I don't care how "waterproof" the radio claims to be, it still goes in a bag. That's the best $20 insurance policy I've seen so far.. The bag also has a nice lanyard to tie the radio off (to the boat, to you, whatever).
Besides water-resistance, should he be considering the transmit power?
