When we want to save grams and space but don't want to sacrifice safety, we take to the skintrack with the ARVA Evo5+ Beacon strapped to us. Weighing less than 6 ounces and measuring smaller than our cellphone, this beacon hits the marks for light and compact, yet it remains packed with features like group check, marking, and signal-interference management to keep our emergency response efficient and auto-revert to keep us safe in case of a second slip during our search efforts. Plus, this iteration of the Evo5 features new software to keep us up to date and a slider that locks when in the off position, so we don't accidentally drain the battery when it's not in use.
