Aqualink View Digital Aviation Personal Locator Beacon PLB/GPS includes a holster. The AquaLink View personal locator beacon 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. Upon activation, the high-visibility screen displays a continuous stream of crucial data, including:Your exact GPS coordinates, Remaining battery power, and Visual prompts for correct deployment. In self-test mode, the screen reports status of the 406 MHz signal, GPS acquisition and battery power, and provides notification of required actions, such as "Send for Service.”
