The AquaLink View 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 callto orbiting satellites. As local Search and Rescue is deployed, a seperate homing signal and integrated LED strobe light guide rescuers to your exact location. The AquaLink View sports a digital display that allows you to see all of the beacon's operational activities. The screen displays GPS LAT/LON, operating instructions, usage tips, transmission bursts as well as battery power. The digital display also makes self-testing your beacon simple and easy to understand by visually walking you through the self test step by step. No more relying on listening to beeps and looking for LEDs.
