Note on Use of the Supplementary Pro Check Feature in the Barryvox S

The supplementary “Pro Check” feature is an extension of the Barryvox S standard Group Check available only when the "Pro Search" function is activated.

Instructions for activating the Pro Check function are in the Barryvox S Extended Reference Guide (link).

This new feature is intended for guides and advanced users who want to see additional details of each transmitter within their group, as a tool to identify when the parameters of one transmitted signal might cause searching problems such as a higher incidence of signal overlap within the group. It is not a feature most rescuers should use every day and it is not considered a “critical check” like the standard Group Check feature. Specific guidance may be found on our previous blog post, HERE (link)

Recent reports indicate the Pro Check feature sometimes gives erroneous “out of tolerance” readings with some Backcountry Access (BCA) Avalanche Transceivers.

About The Supplementary “Pro Check" Feature in the Barryvox S

To best understand how to use Pro Check some background is helpful. All avalanche transceivers worldwide adhere to the same legal standard, or “norm”. This norm ensures compatibility between all transceivers worldwide, thus every transceiver is able to search for others and to be found by others, independently of the transceiver brand and model. Although all manufacturers operate under the same standard, there are still many older transceivers in use and every manufacturer applies slightly different transmit parameters within the legal framework.  Rescuers should be aware that each different signal within the norm parameters will always work with other transceivers. Some differences between individual signals, in particular in pulse rate, is even an advantage in multiple burial situations as it reduces the likelihood of persistent signal overlap. At the same time, each different signal can create different scenarios when in combination with various other beacons—many of the questions we get can be traced to such issues, so we want to provide people with a tool to see what may be driving the way their beacon interacts with other beacons.

The three parameters you'll see tested in Pro Check are defined by the international norm for avalanche transceivers as shown in Figure 1.

Barryvox S Review by Kel Rossiter of Adventure Spirit Guides


For several years, I had been using the Barryvox Pulse.  I carried that beacon in the field for over 175 days and I used it for literally days of practicing single and multiple burial rescue scenarios.  I was impressed all around.  When I heard that the Barryvox S was coming out, I looked forward to updating my beacon set-up and seeing what improvements Mammut had lined up.


 In Fall of 2017 I started using the new Barryvox S, and I’ve now got a full season+ under my belt with it.  Below, I'll set the scene with my experiences with the original Barryvox Pulse, and then I'll describe that transition to the Barryvox S.  Bottom line, while officially the “S” stands for “Smart”, in my book it stands for “Solid.”

Tech Tips: Barryvox S Group Check Mode

Best Practices: Why To Use The Barryvox S Group Check Mode

It is the simple things that keep us alive and allow us to thrive--and the simple beacon check before headed out in the backcountry is no different.

While doing trailhead beacon checks I have found beacons that are not on, beacons that have dead batteries, and beacons that can send but not search. Simply put, a beacon check can save your life. But is it so simple? Can a beacon check be done incorrectly? What is the “best practice?”

Of course, just about any beacon check is better than no beacon check. The simplest form of a beacon check involves turning your beacon to SEARCH and moving towards your partner, who is in SEND. The number on your beacon should get smaller and smaller as you get closer, confirming that your

partner is sending a signal. If you are testing multiple partners at once, they should all spread out 3m apart and walk past you, and you should see a low number on your screen with each pass.Is this good enough? Not exactly.

Post-season equipment check & maintenance

It's the end of the winter season for most of us in the Northern hemisphere, so unless you are one of the lucky few who has managed to steer your life toward endless winter, it's the perfect time to do a good checkup on your equipment, and take care of any required maintenance now before Fall arrives and it's the last minute.
The next recommended maintenance is shown under "maintenance" in the user settings of your Pulse Barryvox, and accessed during shutdown on the Barryvox S

Airbags should be inspected and dried thoroughly before storage.  Complete instructions on storage and inspection are on page 15 of the user manual HERE (link)

Avalanche Transcievers should be inspected as well.  Apart from signs of physical damage, check the "maintenance date" in the transceiver.  For Pulse Barryvox go into the user settings, go to "maintenance" and the date will show the timing of the next recommended 3-year functional test.  Barryvox S beacons are only one season old so aren't due yet, but you can access this info during the shut-down procedure--turn the beacon off and immediately press the orange flag button to show the date of the next recommended service.  Regardless, remove the batteries from your transceiver for off-season storage--this is critically important for alkaline batteries to avoid the risk of acid corrosion, which can render the beacon unsafe to use and is not covered under the warranty.

If you're due for maintenence, either test it on your organization's Barryvox Tester or contact Mammut Customer Service to arrange having this test done during the off season--we get flooded with requests in the fall and get backed up so make sure to take care of this now!  You can reach Mammut North American customer service to arrange this or to ask questions at (800) 451-5127.

Outdoor Gear Lab names Barryvox S Best Avalanche Beacon

In a world of soundbites that rarely get beneath the surface, we certainly appreciate the media outlets who put the extra effort in to spend real time with product and get to know them.  For many people Outdoor Gear Lab has become one of a few go-to websites for in-depth product reviews, so we're super psyched to hear they really liked the Barryvox S Beacon, awarding it their "Editors Choice" for best overall avalanche beacon.  Thanks!  You can read their full, in-depth review HERE (link).

SAFETY CHECK AIRBAG SYSTEM 3.0

Mammut has issued a notice to users of the 3.0 airbag system to check that the installation of the airbag in the backpack is correct.  The 3.0 system has a NEON ORANGE trigger handle and balloon.  The older 2.0 and 1.0 airbag systems (RED trigger handle and balloon) are not affected.



In some cases, incorrect installation of the airbag system in the pack may have caused significant bending of the deployment cable. This could have a negative effect on the functioning of the avalanche airbag after repeated deployment. If you identify the installation problem described in the instructions, please rectify it immediately in accordance with the following instructions (link)

*Note that the black plastic cable covering is cosmetic only, and it's normal for it to exhibit some cracking or peeling--this has no effect on the function of the airbag and is not a problem.
