A high course can be a pre-fabricated, skilfully set up course, constructed of energy poles, cable televisions, and bolts, or it can be a course that is hand-built in a wooded area, where ropes and wire are attached to different trees. Benefits of a static course consist of facilitator, being able to get more participants up on the course at one time, and allowing participants to do numerous elements without having actually to be lowered and climb back up after each. On a dynamic course, individuals are linked to a rope, which someone on the ground will be holding onto and belaying the individual on the course.
