The Ulti-Boom Pro from Ultimate Support is a telescoping microphone boom that adjusts from 20 to 35 inches in length. Using the knob on the ball-in-joint boom arm clamp, you can take control of tilt, pan, depth, and rotation. Use the "StableLock" lever to securely adjust the telescoping tube length. It features a .65-pound die-cast zinc counterweight to help prevent tipping, and the architectural anodized finish helps to prevent rust or corrosion of the aluminum tubing. Use for overhead mics, cymbals, vocal mics, and much more.
