Backup GPS/cell/radio
do you or what do you use for a backup gps. cell, radio?
I'm wondering what I would do if my batteries died on the boat. I'd have no gps for location, no 2 way radio to call for help. I may have my cell phone.
I was looking for a water resistant gps/cell phone but couldnt find one. I did find a gps/2 way radio from garmin. Pretty pricey though.
Curious what others use or am I being too cautious?
