Descenders and Figure 8s are great tools for the professional and recreational tree climber. Figure 8s
and descenders are used to apply friction to the climbing line and control the rate of descent. In case of
an emergency, a figure eight or mechanical descender like the Gri Gri allows the tree climber to make a
rapid descent. Prusik cords can also be used to control a climber's descent, or to back up a figure 8.
The Tree Climber's Companion and On Rope are two great books that contain information on using
figure 8s and descenders to rappel.
