The American Mountain Guides Association is continuing to put out some really good videos with Outdoor Research. In this video, AMGA Instructor Team Member, Olivia Race, demonstrates three different types of improvised rappels.
1) Six Non-Lockers
This is the classic "Freedom of the Hills" style system that every climber engaging in multi-pitch climbing should be aware of.
2) Double-Stranded Munter
This is a much simpler concept. But it can result in some significant twists in the rope.
3) Three Locker System
This final system is a more modern variation of the first system listed here.
It's important with each of these to ensure that nylon isn't rubbing nylon and that ropes are not running over gates.
Check out an in-depth breakdown of each system below:
