Slaphappy posed a very good question asking if any of us had any experience with either being located using a transceiver or "saving" someone else. As seems so typical of this forum, most of the responses were the childish smart-assed wise cracks that we have come to expect from many of the regular "contributors". However, here are some real experiences.
A few years ago three of us were skiing the hill sides above town when one skier triggered a slide. We were all wearing beacons and carrying probes and shovels. Fortunately there were visual clues to the location of the victim and I was able to start digging within probably two minutes (time flies...). I uncovered his face - he had a weak pulse and I could detect a faint breath with my bare hand, his lips were blue and face was bluish grey. He was face down and took several (maybe 5?) more minutes to dig out to the point that I could have turned him over to do CPR had it been necessary. There was no trauma altho one leg was bent up over his back (the ski was still on). He was lucky that there were visual clues - had a beacon search been required it would have added two or three minutes to the rescue, but I am convinced that I still would have found him in time. Without beacons and with no visual clues it would have taken several hours for the two of us to probe for his body.
The same year a patroller in bounds in our local area was buried and located with his beacon. He was dug out alive, but ironically was reburied and killed by a second slide.
A few weeks ago we were standing at the base of a local ice climb that is a notorious avalache gulley and I asked a couple of newbies with their shiny new tools if they were wearing transceivers. One said, "no, why". I pointed out that he was standing on the top of the avalache cone and that I had been buried in that very spot some years ago. We belayed from the safety of an outcrop next to the cone.
Each year I do a week long back country tour in B.C. with a guide who is one of the Rogers Pass avalanche control people (I would consider him one of the few avalanche "experts" in the Northwest). Do we wear beacons - absolutely; do we practice with beacons - of course; if your lady friend were skiing with us would she be wearing a beacon - damn right she would be. In fact, I would probably give her the digital beacon because she might be searching for ME.
Slap, a final note - as one who occasionally gets to go out and rescue the injured and retrive those who don't make it - you and your friend would make our work much easier by wearing a transceiver if you do get snuffed - probing for a body is no fun at all.
