The Effect of Consumer Electronics on Avalanche Beacons


Mammut's Ilari Dammert Presents Poster at ISSW 2014




In the past few years, there has been a growing concern in the avalanche rescue community that consumer electronics interfere with avalanche transceivers ability to function properly. We have always known that metal objects like shovel blades or even foil wrappers can create electrical interference, but today just about every backcountry traveller is equipt with GO PROs, iPhones, VHF radios and other high frequency gadgets.

In an effort to further our understanding of this important topic, Ilari Dammert (Mammut Electronics Product Manager) and Erwin Meister (Project Manager CCS Adaxys) teamed up to explore the issue.

MAMMUT presents "Intelligent Search" poster at ISSW 2014




Ilari Damert, Mammut's Electronics Product Manager, is presenting a poster/paper on the PULSE Barryvox's "Intelligent Search" function which was added to the 4.0 Firmware update last January. Intelligent Search is an optional feature in the PULSE 4.0's Advanced functions which makes fine search faster and more efficient. More information can be found at mammutavalanchesafety.com.

This poster presentation can be viewed on Friday at ISSW Banff. Ilari Damert is also available at the Mammut booth at ISSW. Please stop by the booth is you have any questions about this ground breaking function.

Mammut visits the ISSW and IKAR conferences--stop in and say hello!

Mammut representatives will be attending the ISSW (International Snow Science Workshop) in Banff as well as the IKAR-CISA (International Commission for Alpine Rescue) hosted by the Mountain Rescue Association in Lake Tahoe.

On Friday October 3rd at ISSW at 11:40am in the Kinnear Center room 303/305, and again on Tuesday October 7th at IKAR, Mammut avalanche equipment product manager Ilari Dammert will present a paper he co-authored on "The Effect of Consumer Electronics on Avalanche Beacons".  Limited copies of the paper will be available at the Mammut booth if you aren't able to make the presentation. 

Please stop in and say hello to the folks from Mammut.  During intermissions people will be available to answer questions.  Also, bring your Mammut avalanche beacons if you need a checkup or a firmware update. 

We hope to see you there!

My Gu packets interfere with my beacon!?? Really?


It’s summertime, and few of us have avalanche beacons occupying our attention (if you do, please send a postcard!). Nevertheless, the other day I was part of a conversation that readers of this blog will find very interesting.  It started as many of these do, an email from an acquaintance about his buddies’ beacon. 

I have a friend who has a Pulse that occasionally beeps and displays something like “457 failure to send” (I’ve been with him when this happens). How can he get his beacon fixed/replaced?”

I replied that the “457 Send Failure”(LINK) screen prompt is actually there to alert you when your beacon experiences EXTERNAL interference from an electrical, metallic or magnetic object.  My friend, Steve Achelis of www.Beaconreviews.com , knows his stuff and remarked that they were way up on Mt Rainier where there should not have been any interference, and that none of the other group members had a problem.
My last response was “OH--last thing I thought of, a lot of people get this from a metallic foil wrapper (powerbar or the like) or electronic gizmo in the chest pocket of their jacket (right on top of beacon)....”

Svalbard Sail/Ski 2014

Today, I repair the core shot from the only rock I hit in Svalbard, Norway during the last week of May. I was lucky enough to accompany 5 good friends and clients to Svalbard, Norway on the Aliega, a 65 foot sailboat based in Svalbard, Norway.

Service Bulletin for Inspection of Mammut and Snowpulse Avalanche Airbags

Inspections have shown that there is a possible assembly problem


affecting individual Mammut and Snowpulse avalanche airbags from the Winter


2011/2012 and Winter 2012/2013 production seasons. The problem is an improperly

screwed in connector between the deployment mechanism and the venturi valve.
Since Mammut cannot rule out that this problem could result in a loss of function in the event

of use, we hereby request that all customers inspect the connection in accordance with the

Tech Tips: Creating a "mental map" during multiple burial searches

Recently, I had the opportunity to participate in a group training with Mammut Snow Safety technical rep Doug Workman where we spent a morning practicing some of the advanced functions of the Pulse Barryvox transceiver.  Generally, this beacon allows either single or multiple burial searches to be accomplished extremely quickly and easily.  However, when a searcher confronted with a close proximity multiple burial runs into the problem of signal overlap, as with any digital beacon, things fall apart--when overlapping signals are present digital beacons struggle to differentiate the signals. In such instances, searchers need to recognize what is going on and revert to a backup method to conduct the search.

One of the most fundamental things I took away from the session was the importance of the "mental map" that a searcher can use during a multiple burial search by integrating analog information into a typical digital search.  By "mental map", I mean that as you progress through a search, you can quickly and easily form a mental picture of not only how many burials you are dealing with but also where each of them is relative to each other.  Why is this important?  Because this "mental map" allows a searcher to see and react to signal overlap problems AS THEY HAPPEN, rather than realizing what's going on after a problem occurs.

Mammut You Tube Instructional Videos

If you own or use any of Mammut's avalanche safety products, you should become familiar with Mammut's You Tube channel, which is full of many instructional videos: Mammut Avalanche Safety You Tube.



Today, I would like to highlight the videos which demonstrate the proper use, re-packaging, and removal of the Protection Airbag System (PAS) and Removable Airbag Systems (RAS).

If you already own or are thinking of purchasing a Mammut PAS or RAS airbag, please watch these short videos to ensure proper use of your airbag system.

New Year's Deep Slab Avalanche Cycle--Jackson Hole

Deep slab instability has been a widespread plague this winter throughout North America. Jackson Hole has not been immune. Currently, in the Snake River Range, a deep faceted layer up to 80 centimeters thick sits at the ground topped with an 80-100 centimeter hard slab. These slabs are quite strong and can support the weight of many skiers. However, if a thin spot is found, or if a heavier load is applied (like a snowmachine), the results are dramatic. Today (1/18/14), a week after the storm cleared out,  a snowmachiner triggered a deep, hard slab in the Palisades. This persistent weak layer will not go away quickly.

Below are photos from the last week's avalanche cycle in the Snake River Range in Wyoming and the Palisades in Eastern Idaho.
