Hmm I donnu, lets see if my and my buddy are both buried with beacons and shovels can we save each other? If me and my buddy have beacons & abs packs, and one of is lucky enough to stay on top due to the abs bag and then able to dig out the other....by GOLLY.. I think I just figured something out OLE bean.. By putting my self in a position to less likely be buried I'm putting myself in a position to more likely be able to help my buddies. Who would have thought of that.. Wait wait.. I know your going to say if you didn't cause the slide in the first place blah blah... ...yes yes we all know but we are talking hypotheticals here.
Dude do you honestly think that if one of you survives and avy with your avy bag while your other buddies avy bag failed causing him to buried that your going to be in condition to turn your beacon on "search" let alone use your shovel.
If you own an avy pack you must be a test dummy waiting to happen.
