I just got back from a three day snow caving trip and used the Life-Link Snow Saw to cut my cave. This was my fifth year snow caving and, this time, I decided I wanted to cut sections and basically block the cave out instead of chipping with shovel alone. I essentially dug out a 8' wide by 8' deep by 5' H cave in about 6 hours (including hauling snow out and including breaks). Very pleased with product. ALSO! It's thin and light and fit easily into my pack. One recommendation: Be mindful of the tool around your gloves and ski gear because it's got some teeth.
