With three levels of integrated signal technology – GPS positioning, a powerful 406 MHz signal, and 121.5 MHz homing capability – the ResQLink 400 quickly and accurately relays your position to a worldwide network of search and rescue satellites. Additionally, a built-in strobe and infrared strobe facilitate nighttime, or other low visibility, rescues.

Simply deploy the antenna, press the on button, and the beacon will do the rest for you by effortlessly guiding rescuers to within 100 meters or less of your position.

Due to innovative design elements, multifunction clips can be used in conjunction with the beacon, providing numerous wearability options that address a variety of usage applications. The increased ease of incorporating the ResQLink 400 on your person, or with your gear, just made all your adventures not just safer, but more convenient too.

    *Make sure the antenna is pointing towards the sky, out of the water. Beacon is not intended to operate in water. While the unit is waterproof, it must be above the water’s surface to function properly. Intended operational environments include on-ground, above-ground, and held in hand. In all cases, the beacon must be facing skyward with the antenna perpendicular.
