Does anyone have experience with the Standard Horizon HX851 handheld? It is advertised as submersible, floating, with a built-in GPS (for a backup, DSC etc). At about $200 it seems like it might be a good option, although I am concerned about a) apparently 10 hr battery life and b) size. Is it better to go with a large but floating radio attached to the boat, or a small non-floating one attached to a lifevest?
Thanks for your input!
