Swiss startup Airmarker delivers that type of added safety layer in a bid to help both wilderness adventurers and search and rescue (S&R) teams. Its all-new survival beacon sends up a visual signal that lasts much longer than a flair and works regardless of cellular or satellite coverage. It rises above trees, peaks and cliffs, where it can identify a victim's location from the ground and air. The Swiss seem to love themselves some bright-orange mountain rescue balloons. The minute I spotted the all-new Airmarker, it transported my mind back 12 years to one of my first articles here at New Atlas, then Gizmag. It concerned a device called the Rotauf MRK5, an avalanche safety gadget that auto-inflated an orange balloon attached to the user via a rope. The balloon was designed to float atop the snow, even if the skier was buried by the avalanche, with the intent of saving invaluable minutes when locating and digging out the victim, helping boost their chances of survival.
