Glidecam X-20 is designed to hold film and video cameras weighing from 10 to 20 pounds. It includes X-20 support arm, support vest, X-20 support sled, docking bracket, arm post, hardware and operations manual. The X-20 system incorporates advanced engineering and precision machining, making it the most sophisticated and versatile system. The X-20 system will allow you to walk, run, go up and down stairs, shoot from moving vehicles and travel over uneven terrain without any camera instability or shake. The X-20 system works by isolating your body's motion from your camera, while your camera is balanced in a relatively motionless and isolated state. The X-20's support arm can be boomed up and down, as well as pivoted in and out, and side-to-side. It is the combined low friction booming and pivoting action of the support arm that isolates your body’s motions from the camera enabling you to create super smooth moving camera footage.
