John A.wrote a review of Black Diamond QuickDraw Guide Probe 300 on May 11, 2014
Familiarity: I've used it once or twice and have initial impressions
It's a probe... pretty straight forward. Practiced with it a few times, and seems like it will hold up well. I would definitely recommend getting the 300 cm if you ski in areas that have a deep snowpack. It's amazing how quick you can burry to the handle when you're doing your snowpack analysis in the PNW and other areas that get a lot of snow. A great deal at Backcountry.com now - as inexpensive as any 'economy' short probe.
