RECCO reflectors are another form of safety tech that is used by search-and-rescue units during avalanches. The reflectors are actually thin devices that are incorporated into jackets, boots, helmets, and other items during manufacturing. These offer a battery-free and hassle-free way for searchers to find you in the event you are ever in an avalanche.While avalanche beacons do not typically work with RECCO reflectors, neither technology interferes with the other. As such, both can be used simultaneously.
