To achieve more friction with a Figure 8 with ears, what should you do before descending?

Using a double wrap with a Figure 8 with ears is an effective technique to increase friction before descending. This method involves wrapping the rope around the figure 8 twice, creating more surface area and contact with the device. The increased friction generated by the double wrap helps to control the speed of descent, making it safer and easier to manage.

This is particularly important in rescue scenarios where precision and control during descent are critical, as it allows the user to slow down or stop their descent if needed. The additional friction also helps to prevent accidental slips, enhancing overall safety for the rescuer.

In contrast, other options such as single or triple wraps may not provide the optimal balance needed for safe descent. A single wrap may not offer sufficient friction, while a triple wrap could potentially create too much friction, making it difficult to descend smoothly. Using a locker helps to secure the system but does not inherently increase the friction against the figure 8 itself, which is why the double wrap stands out as the best option for achieving increased friction during a descent.
