Call for Inspection of Airbag Systems 3.0


SAFETY FIRST: Mammut asks customers to check that the airbag balloon is correctly attached to the airbag inflation system.

Product safety and quality are the number one priority for Mammut. For this reason, Mammut is asking customers who own Generation 3.0 Mammut avalanche airbags to check whether the airbag balloon is correctly attached to the airbag inflation system in order to ensure that their avalanche safety equipment functions correctly.


All customers who own a Generation 3.0 avalanche airbag from the Winter 16/17, Winter 17/18 or Winter 18/19 seasons (neon-orange colored deployment handle),including Mammut airbags in packs manufactured by Highmark by Snowpulse or other brands utilizing 3.0 airbag systems, are requested to check them according to the following instructions or to contact Mammut Customer Service. Avalanche airbags from previous seasons (2.0 system or earlier with red deployment handle) are not affected.

It is easy to identify whether the airbag is attached correctly (see the inspection instructions HERE link). If the airbag balloon is not properly attached to the airbag inflation system, in some cases the airbag may lose volume too quickly after deployment. As a result, the airbag’s functionality may be impaired in the event of burial by an avalanche.

If you identify that the airbag balloon is attached incorrectly, the affected airbag system should no longer be used and must be returned immediately to Mammut Customer Service to be replaced. In the event of any queries, Mammut Customer Service will be happy to help.

Thank you for reacting to this call for inspection - Safety First!

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.”
