ACR Electronics, Inc. doing business as Cobham Life Support 
Head offshore with confidence. With three 
levels of integrated signal technology — GPS 
positioning, a powerful 406 MHz signal and 
121.5 MHz homing capability — the AquaLink™ 
quickly and accurately relays your position to 
a worldwide network of Search and Rescue 
satellites, reducing search time and increasing 
your chances of survival. It’s reliable signaling 
technology that has saved more than 26,800 
lives since 1982.
The AquaLink™ broadcasts a unique registered 
distress signal that not only tells rescuers 
where you are, but who you are. The onboard 
GPS can fix your position to within 100 meters 
and then utilizes a powerful 406 MHz signal to 
relay your distress call to orbiting satellites. As 
local Search and Rescue is deployed, a separate 
homing signal and integrated LED strobe light 
guide rescuers to your exact location.
The AquaLink™ is small enough to be easily 
carried in a pack or pocket or can be worn 
on deck, at the helm, in quarters or on a life 
vest and will float if accidentally dropped 
overboard. Performing a full functional self 
test of the PLB’s internal circuitry, battery 
voltage & power, and 406 MHz transmission 
gives you peace of mind knowing your PLB 
will work the moment you need it most. ACR 
Exclusive: Built-in GPS acquisition test mode 
allows you to test GPS functionality up to 12 
times over the life of the battery.
Tap in to the same field-tested rescue 
technology used by the U.S. Military, U.S. 
Coast Guard, NATO Special Forces and Arctic 
explorers.

It is mandatory that you register your PLB. It’s fast, easy and free 
www.beaconregistration.noaa.gov. When activated, the unique identification code in 
your PLB is linked to the registration database. This way authorities can retrieve valuable 
information about you and your trip
The AquaLink™ is a satellite signaling device of last resort, for use when all other means 
of self rescue have been exhausted, where the situation is grave and imminent loss of 
life, limb, eyesight, or valuable property will occur without assistance
