Testing the Figure-8 Device Block for Canyoning

Testing the Figure-8 Device Block for Canyoning

What’s in this post? Slow Pull testing the figure-8 device block variations with normal loading and incorrect loading. We also compare this to baseline methods such as the Munter mule overhand and figure-8 on a bight. Efficiency tests (speed) to find out if there is there any major differences in tying methods. Practical use comparisons […]
