Shopping? This is a good beacon/probe/shovel package.

As a rescuer, I've responded to avalanches that involved almost a dozen fatalities. (now in its 17th year) was created to share what I've learned about avalanche transceivers and avalanche rescue. My goal is to provide current, independent, and scientifically objective information.

You can jump to the transceiver summary if you're in a hurry, but don't forget to check out and to practice frequently.

Stay Safe,
