My go to cam
There is not much to say. I just got back from 7 days of straight climbing at Indian Creek and I can safely say that the black diamond c4's are amazing. Not only are they light, but the double axle design gives them an impressive expansion range which REALLY makes a difference when you are pulling a crux move and need to plug and chug without fumbling around trying to find the perfect size. I took multiple lead falls on my lucky c4 #2, and it did not budge an inch. Among the group of 4 rock climbers that I climb with we have close to 80 years of climbing experience, and we all agree that c4's are completely dependable and durable.
