Petzl Shunt: Mechanical Prussic
Review by: vdotmatrix, 2006-11-17
While climbing in Kootenai Canyon south of Missoula years ago, i had to rap down under a roof to retrieve some gear. I had to let go of my brake hand and fiddle with some gear. My full weight on the rope welded my prussic cord to the rope and there I was under a roof project, where i was stranded for the better part of 2 hours, in the drizzle and twillight....This was before I started carrying a sharp knife, before Vertical Limit, before I always carried runners, t-blocks and smoke flares. Anyway, I wanted to get as far away from prussics as possible when i bought a Petzl Shunt-a mechanical prussic. The thing is relatively heavy. You need a little extra gear to use it. But on full length rappels I like it over an auto-block, which is slow and if it isn't slow , I am always worried of sawing through the auto-block with rope friction- which is a matter of preference. I use it on bigger climbs when I want a little extra margin....the heck with my lightweight, purist 5 peice gear rack climbing collegues who hate to see anyone with more than 6 pieces on their rack or extra gear.....screw them...... Try this thing, it has a good use when ya need it for that. BAMMMM!
