Why We Like The Mammut Barryvox S Beacon

Compared to the standard Barryvox, Mammut's Barryvox S Beacon has more advanced features that appeal to experienced mountaineers and guides. The beginner-friendly interface remains, while the larger screen displays advanced graphics, the additional buttons allow for customization, and the lithium batteries prevent corrosion to give us reliable performance when we need it most.

Best most intuitive

Time counts in an avalanche search. This is foolproof and intuitive — technology plus ease of use gives the best chance for rescue when a life is on the line.

Work and play

Use this on the daily ski patrolling. Also have a personal one for recreation in the backcountry. Once you spend time and dial in the extra features it’s the best tool out there.

Barryvox S_uper Happy

Has everything I was hoping for and more - small, relatively straight forward (spend some time with it before heading out, duh), excellent range and orientation. Once you spend some time practicing with it everything is logical and effective. Beginners or those who don't frequent and maybe take short cuts on reacquainting, might look for something a bit simpler.

Best beacon

This is simply the best beacon you can buy. Reliable, durable and easy to use. Everything you need in a beacon without anything unnecessary. Highly recommend and won’t use anything else when life depends on it.

An amazing beacon

I love this beacon, I've been using it all season at work as a ski patroller. It's an easy beacon to use and I have yet to run into any real issues with it.

Solid, Reliable Beacon

Seems like a great choice for a beacon. Good features, reliable, and easy to use with gloves on. Hopefully I never have to use it!

Amazing beacon

This beacon is extremely easy to use. It's range is out of this world, and for Search and Rescue practice is absolutely perfect. My only complaint was, that the owners manual did not come with the product. I had to search it on line and it was not easy to find the correct manual that gave the advanced features.

Substantially increased pickup range vs competitors

I switched to the Barryvox S from a Tracker 3 and have noted that it routinely picks up an initial signal significantly further than other options, often 60m+, which gets you into course search mode much faster. One thing I have noticed with the Barrvox is that the refresh rate seems to be much slower than some other beacon options. This forces you to slow down during fine search and really be patient with your readings, which isn't necessarily a bad thing, but is something to be aware of. The Pro mode has a lot of features that are really confusing if you don't practice with them. However, I really love the analog mode, even for recreational purposes because it allows you do easily demonstrate electronic interference to companions or guests. I don't think that warrants everyone getting the S version, but this feature is helpful even for advance recreationalists who may be mentoring newer folks.

Good features. Solid case

I've used it once or twice and have initial impressions

I bought this hoping it would be easy to use. Easy to follow screen display. Loving it so far.
