This boom is perfect for the general studio or low-angle applications that other booms can't handle. With the angle indicator, you can easily repeat a setup. The rotating head has an angle indicator that rotates the head 360 degrees on its arm. A unique double-beam parallelogram design maintains the angle of light as you move it up and down. For more reach, optional head extensions are available in 18, 24, 30 and 48" lengths.
