Black Diamond QuickDraw Guide Probe 300 from Backcountry.com
This is what I have. I went with a 3m probe for easier time reading depths. If I wanted to dig a pit down to the ground just less marking and easier to see depth of snowpack. The snowpack was fat last year for sure and I am a firm believer I would rather have over kill if I was trying to find someone in case there was a really deep burial.
