"Mayday" beacon beckons rescuers.

A new emergency rescue beacon on a deployable buoy helps rescuers locate vessels at sea with nearly pinpoint accuracy. The emergency position indicating radio beacon (EPIRB), made by the Special Devices division of Litton, Springfield, Pa., can automatically transmit an emergency radio signal to polar-orbiting satellites--either the U.S. SARSAT or Russian COSPAS satellites. The signal is then relayed to ground stations for calculation of the craft's location within one to three miles.

Model 948 EPIRB substantially increases the accuracy of locating mariners in distress by offering transmission of two signals on different frequencies. Compact and self-contained, the units are housed in a sealed case molded of Makroblend DP-4-1368 polycarbonate/PET polyester blend from Miles Inc. The impact-modified material provides the strength, durability and impact resistance at low temperatures that is required for harsh marine conditions. The blend also offers good chemical resistance, fire retardance, ultraviolet light stability, and colorability.

The bright orange and yellow rescue beacon is mounted securely to the deck, pilothouse roof, bulkhead or other readily accessible locations on maritime ships, fishing vessels, pleasure crafts or other boats. Two versions are available--one that will deploy automatically if a vessel sinks or capsizes and another that can be activated manually.
