The DSC option with gps could help a SAR case, especially if you don't have much time to abandon your vessel, and spend a lot of time describing your boat and problem. There is nothing like flipping up the cap and pushing the distress
button. If you are on the Great Lakes
, most of the time you will be within tower range of the Coast Guard. Your biggest concern is to ensure you have 12 volts to make the call. Dead batteries are one of the biggest problems with boats. I have been working on emergency
back up battery
systems, or designated batteries that only run the radio
. The best dependable back up for loss of electricity, is a PLB that floats, or EPIRB
with gps if your concern is getting help quickly..
