gps embedded lifevests anyone?
If the vests had a metal foil attached, they would show up on RADAR.
The Coast Guard and the Auxiliary urge people to connect their GPS units to their VHF radios; using the new Rescue 21, any distress call will give an accurate position.
Depends on the size of the craft. Large boats will have EPIRBs to send distress/location signals to satellite. Small boats generally only have life vests (or should have). VHF radio signals from a small boat in rough seas are also very iffy, especially considering the distance off shore.
I’d have a personal EPIRB if I had NFL type money!
