Figure 8 descenders are most suitable for which type of load?

Figure 8 descenders are primarily designed for single person loads due to their construction and functionality. These devices provide a controlled descent, allowing the user to manage their speed effectively while descending. This is particularly advantageous for situations where a single rescuer is rappelling or lowering themselves, as they can handle their own weight and the forces exerted during the descent.

The design of a figure 8 descender allows for smooth operation and ease of control, making it ideal for individual use. When used with a single person, the descender can effectively dissipate energy and manage dynamic forces, thus ensuring safety and reliability during the operation. It is not typically recommended for double person loads or heavy loads, as the dynamics and potential for uncontrolled descent can increase, leading to unsafe situations. Similarly, while it can be adapted for unstable loads, the figure 8 descender is not specially designed for that purpose; its primary function lends itself to steady, controlled descents by a single user.
