McMurdo won an order from the U.S. Coast Guard worth up to $7,500,000 over 5 years to supply 406 MHz FASTFIND PLUS Personal Locator Beacons (PLBs) equipped with integral GPS.  This represents an upgrade from the standard FASTFIND PLB, a similar quantity of which was supplied to the U.S. Coast Guard over the past 3 years.

The PLB is a handheld beacon which is registered to the individual user. When activated, the Fastfind Plus provides a 406MHz alert signal via the COSPAS-SARSAT satellite system to Search and Rescue authorities. There is a visual indication of GPS acquisition. Fastfind Plus also transmits on the International Aircraft Emergency Frequency of 121.5MHz providing a homing signal for the Search and Rescue (SAR) services.
