This accessory for the Cheetah Boom allows you to use the boom arm as a reflector holder. It comes in two pieces. One piece goes into the end of the boom arm where you would normally attach your light. The other piece clamps on to the boom arm itself. You can then adjust the length of the boom arm or position of the clamp to use different size reflectors.
The advantage of using the Cheetah Boom as a reflector holder is flexibility. Using a large reflector as an overhead scrim or reflector is easy when combined with the boom arm. You can also position the reflector at a low angle to kick light up toward your subject from the ground. The possibilities are only limited by your imagination.
