Professionals in the ski community have trusted Mammut for years due to their reputation for making the highest quality products that manage to be packed full of important features while still being quick and easy to use - the Barryvox S is no exception. Despite its simplistic design, the Barryvox S is packed full of useful features. One of the more handy and important features is the Rescue Send mode--allowing rescuers who are not leading the search to keep their beacon on without transmitting or searching. This is combined with the built-in Auto-revert function that will automatically switch the beacon from Search mode or Rescue Send mode to Transmit mode if the user becomes immobile for 4 minutes in the case of a second avalanche. It also has an auto-guidance function that will continue to guide the rescuer in the case of signal failure or overlap. The 3D sensor can help the lead rescuer concentrate their resources on the victims that are closest to the surface and have the highest likelihood of survival. When switched to analog mode this beacon has an incredibly large search range with a receiving bandwidth up to 95 meters. It also functions with lithium batteries, which have a much longer battery life and make it more stable at lower temperatures. The display is backlit, making it easy to see even while wearing polarized glasses or goggles, and the ergonomic design makes it easy to operate with gloves on. With all of these features and more, the Barryvox S is the perfect choice for professionals in the ski and backcountry industry.

Alex (downright abused product)
This is my 2nd season with this beacon and have over 100 days of use. It has been great to wear in the harness or in a pocket, its intuitive and gives a lot of extra features to test scenerios with. If you can afford the price I think its absolutely worth it for the extra range. My only gripe is that you have to pay to get the software updated? I understand everything costs money but if the consumer is already shelling out the $$$ it seems a little nickle and dimey to have to pay $30 or $40 to get the software updated every year or two.
