We've said it before and we'll say it again: don't compromise when it comes to avalanche safety gear.
 
The Mammut Barryvox® three antenna digital/analog combo avalanche transceivers have a large receiving bandwidth and an effective search strip width of 70 meters. They offer users a large, simple interface and intuitive operation, along with buttons that can be operated even wearing gloves, shock-proof and break-proof housing and a revolutionarily simple visual interface, delivering powerful performance and sophisticated search guidance. 
 
Go with the standard model if you're on a budget but still need top quality and performance on the essential functions.
 
Both Barryvox transceivers sit as the most user-friendly, most efficient search tools available, but the Barryvox S is a cut above. However, just because it’s got more features doesn’t mean it’s harder to use or for more advanced users! Here are the top benefits you'll see from opting for the Barryvox S over the Barryvox:
 
Larger Screen (2.2” vs. 2") – easier to see & read, even with the lighting is bad.
Dynamic Screen Icons – the icons move as the searcher does, indicating exactly what the searcher should be doing (i.e. Is the icon running? The searcher should be doing a quick coarse search. Is it crawling? Time for a pinpoint search).
Rescue SEND – In the event of a secondary avalanche, the device automatically switches to SEND in order to locate buried rescuers.
Smart Search – though the user never sees this feature, it operates in the background and makes searching more efficient than ever – even if the searcher is less than perfect.
Auto Guidance – no more signal overlap from other transceivers. No more “stop stand still.” Just a one-track path to the buried victim.
Lithium Batteries – the Barryvox S can utilize Lithium batteries or alkaline batteries. Lithium batteries last longer, are lighter and don’t damage with acid corrosion.
