If you often head expeditions off shore with the yacht’s owners or a charter party, consider tossing the ResQLink into the tender and take it with you when you explore.

Chances are you will never use it, but this device, small enough to fit in the palm of your hand, could help save lives when the unthinkable happens. It is compact, fairly inexpensive and early reports say it’s easy to use.

The ResQLink is a powerful, waterproof and FCC-approved personal locator beacon. Manufacturer ACR Electronics (part of Cobham Beacon Solutions) says ResQLink is accurate within 328 feet (100 meters) or less. Containing three levels of integrated signal technology—GPS positioning, 406-MHz signal and 121.5-MHz homing capabilities—ResQLink can quickly relay critical position information to the International Cospas-Sarsat Program’s worldwide network of rescue satellites.

The information includes the sender’s location information and identity. When all other means of self-rescue have failed, this device gives pilots, boaters and outdoor enthusiasts in distress a fighting chance. Early reviews are in and mostly positive, except for the instruction manual, evidently a little light on clear directions. This small device retails for less than $300.
