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.

Questions & Reviews
My full impressions are provided at the Beacon Reviews website in the entry for which I collaborated over there. But in brief, this model has all the bells and whistles if you’re into that, with all sorts of customizing available too. However, you can also set up in a simple mode to keep the various options in the background. Another nice feature is that one beacon can update another beacon with the latest firmware.
The only caveat is to be very careful if you choose to use lithium batteries. The power meters in other beacons have no way of knowing how much life is left in a set of lithium batteries, since their power curve is essentially flat, until it falls off a cliff. For the Barryvox S though – same thing! So it’s estimating how much life is left by keeping track of how much you’ve been using a new set of lithium batteries. Hence, you need to start off with a new set, and not use it any other devices. (Or of course you could just deal with the trivial weight penalty of regular alkaline batteries.)
I'm looking to purchase a barryvox s for a reasonable price all the way from NZ as they are very expensive here! However I need to get the US version as opposed to the EU one as the W-Link of the EU version does not work here. Do you know what version this one is?
I'm not convinced by revert to send mode, so I've turned that option off for me (something you can only do on the Barryvox S and not on the regular Barryvox). I'm not a fan of Mammut's landing strip search, so I've changed that setting to classic as well.
If you know your way around a beacon and want the advanced search (or want to turn off revert to send), I think the Barryvox S is tough to beat. People say that less experienced users might be better off with a Barryvox, but I think even in that case the Barryvox S is the way to go - having the better guidance on screen when searching justifies the price on its own in my opinion.
I work as a ski guide & avalanche educator so I use most of the functions of the beacon a bit more frequently than the general user. The only thing I've noticed that warrants a four-star, instead of a five, is the battery level fluctuations. Occasionally in the morning, I'll get a rating of 70% then later in the day it'll be at 80%. Gone through multiple battery brands and that doesn't seem to be the case. But other than this minor-ish issue, I've found this thing to be an awesome piece of kit.
