ResQLink 400
Small but resilient, the ResQLink 400 has been professionally engineered and tested to ensure it can withstand even the harshest elements. This buoyant Personal Locator Beacon (PLB) requires no subscription for use and includes a digital display providing live status and GPS coordinates. Whether on land, at sea, or in the air, trust that the ResQLink’s satellite precision and military durability, puts rescue in the palm of your hands.
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.
Wherever your adventure takes you, whether it’s a trip to the highest mountain peaks, the most undiscovered terrain, or the vastest of oceans, rest assured that the ResQLink 400 always activates easily. 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 on your person, or with your gear, just made all your adventures not just safer, but more convenient too.
