When to use a beacon:
Most Search-and-Rescue organizations instruct that beacons are satellite signaling devices of last resort, for use when all other means of self-rescue have been exhausted, where the situation is grave with imminent danger and the loss of life, limb, eyesight or 
valuable property will occur without assistance.
An EPIRB is an Emergency Position Indicating Radio Beacon. Sea Tow Foundation uses the ACR Electronics GlobalFIX⢠V4 for its beacon rental program. The GlobalFixV4 has an internal 66 channel GPS for faster acquisition from a cold start. A protective keypad cover helps prevent false activation and a user-replaceable battery pack that has a 10-year replacement interval.
Choose an EPIRB for Boating if:
- Medical conditions of crew or passengers warrant
- Operating a vessel with recent substantial repairs
- Operating in areas inclined to sudden changes in weather
- Operating in areas that are remote
- Operating in areas that are unfamiliar
- Operating in areas with limited cell phone and VHF radio signal contact
- Operating in unreliable waters
- Operating an unfamiliar vessel
- Operating an unseaworthy vessel
