I attended a presentation from an ACR rep regarding EPIRBs. She said one should activate your EPIRB if it's a case of life and death. However you would be hit with a $5000 fine if you activate one just because you happen run out of gas. I can understand and accept these extremes, but it got we wondering - what about the zillions of cases in between. Does anyone know of a more comprehensive set of guidelines, perhaps from the Coast Guard, on when EPIRBs should be activated?
