ACR MicroFix 406 PLB
406 MHz  GPS Personal Locator Beacon

Discontinued. Check out the new AquaLink and SARLink PLBs from ACR>>

MicroFix takes the 'search' out of Search & Rescue. Accidents happen every day in the outdoors, whether you fall out of a tree stand, break a leg during a hike, roll over on an ATV. In the outdoors, an everyday accident instantly can become a life threatening situation, and rescues may take days or weeks if you're not prepared.

Why wait for days? If you're stranded in the outdoors hoping someone will find you, put the power in the palm of your hand with the MicroFix™ 406 GPS Personal Locator Beacon. You can turn that life threatening situation into a successful rescue story.

It's as easy as pushing a button. With an internal GPS receiver, MicroFix™ will acquire your GPS position and transmit it along with your personalized identifier code through the SARSAT satellites instantly alerting SAR forces that you need help, immediately!

The MicroFix ™ works fast. If GPS data is present in the beacon's first burst, SAR forces can be notified and start planning your rescue in as little as three minutes.
