Mammut Barryvox is a classic name in the digital transceiver realm. However, this beacon is not the same old transceiver your uncle used. It has been completely revamped with the intention of being the simplest and most user-friendly beacon to date. Mammut nailed it. The user interface has been improved so one button handles all navigation through the concise menus. The exterior switch has been designed to prevent unwanted mode changes. The large, back-lit screen is easy to read, even if wearing polarized goggles. A 70-meter range and blazing processing speed means that searching is faster and possible from further away than all previous beacons in its class. Improved signaling helps better prevent overlap and eases handling in multiple burial situations. The package is rounded out by one of the nicest harnesses on the market. If you want easy, fast, and effective, add the Mammut Barryvox beacon to your cart.

Of all the beacons I researched, the Mammut Barryvox stood out to me due to its 70-meter range and unique, beeping audio tone that accelerates as you move closer to your target. While I haven't had to use the beacon in a real-life scenario, I feel confident and secure with this device by my side

The beacon is the best on the market, as explained in many reviews on this site and others. The reason I give 4 stars instead of 5 is that the chest harness is trash. The straps are bulky and the plastic holster the beacon sits in is uncomfortable against the body. I don't understand why there has to be a rigid plastic piece that holds the beacon, it's unwearable for me.

This beacon is simply the best on the market imo. Throughout multiple avy classes and dozens of practice scenarios, I consistently see barryvox beacons outperforming the rest in range and success with the marking function in multiple burials. It's easy to understand, the group check function is nice with larger groups, and I'd recommend it to any of my friends getting into the backcountry.

Full discloser I have only used the beacon for status checks and not full scale burial scenarios. That being said, I enjoy the user friendliness and comfortability of carry which makes it easy to carry. I like the harness it comes with and the Barryvox carries nice in a pocket too.

Great beacon. Simple to use, intuitive features, great battery life. I would buy a mammut again in a heartbeat. Intrigued by the S version but the price difference is steep. If you’re on the fence between beacons just buy this one. You’ll love it.

I have had my Barryvox for about a year. The range is excellent, intuitive controls, clearly built for years of use. My go to recommendation for anyone in the market right now
