An Avalung seems like an easy DIY creation to me however I have not had the chance to handle one in person. Will someone who owns an Avalung please comment on the following:

1. How does the air exchanger work? Please try to explain how it allows for exhalation but not inhalation?

2. What are your thoughts on the Avalung II (the basic model) vs. one built into a backpack? If caught in a slide would you be comfortable in one or the other? Both?

High resolution photos of the Avalung II taken apart would be excellent (assuming the breathing apparatus can be removed from the harness). Depending on answers to some of the above questions a DIY Avalung project might be something I would like to undertake.

For others interested in this idea here are some URLs I've come up with to help in my pursuit:

There is a flapper valve in the shoulder of my avalung pack that goes one way when air flows in one direction, and redirects it a different direction when the air flows the opposite way. so basically air always flows out the opening to your mouth, but coming in it is pulled from the "intake" opening. when you start to breath out, the flapper moves and the air is sent to the "exhaust" opening.

I have never used a bandoleer-style (avalung II), and I have never been in an avy (knock on wood) so I don't know how I would feel about one vs. the other, but the backpack style moves intake and exhaust further apart, a theoretical advantage.

If I got caught in a slide. I don't think I would be *comfortable* no matter what I was wearing. :oops: Based on statistics, it sounds like ABS packs are a more useful tool to decrease the likelihood of death or serious injury during an avalanche. I think I've heard discussion on other sites of people chopping a bandoleer avalung into ABS packs to get the whole package

Thanks for the comments, Shep. FYI, the ABS/Avalung mod you refer to can be seen in one of the TGR links I posted originally.
