This is the most advanced beacon on the market. It has a 70m digital receiving range, a fast processing power, and an intuitive digital interface. The most important quality of a beacon is to be VERY well practiced with the beacon through recursive and routine companion rescue training. The second is to have something that works well and is reliable. The Barryvox S fills that roll. It's large digital display that walks you through the progressive steps of a companion rescue is a valuable tool to have access to when the intensity is high in a real avalanche burial. Having a fast processor and high digital range is crucial as well to reduce the amount of search time as much as possible. This is an advanced and powerful tool that will hopefully save my friends like [if that time comes]. There is a step learning curve to understand all of the features behind this beacon, but take it upon yourself to learn those if you're serious about traveling in avalanche terrain. I strongly recommend this beacon to snow safety professionals and active backcountry / avalanche terrain users. This is an advanced level beacon that comes with a high level of performance.
