In a new series on UKClimbing, we have teamed up with Plas-Y-Brenin to find out the difference between a Prussik and a French Prussik. We will be explaining everything from putting on harnesses and tying figure of eights, to building belays and leading; all through the medium of veterans Dave Evans, Dave Rudkin and Jack Geldard. Everyone from beginners to the sport, to experts will find these instructional videos useful for learning and polishing up on essential skills.

In this video, Dave Evans takes a look at the bewildering array of karabiners.
