The GLIDECAM X-10 is very similar in design to the Glidecam Smooth Shooter; however the X-10 comes with both sections of its support arm being able to move vertically, whereas the Smooth Shooter comes with only the front section of its support arm being able to move vertically. Also, the X-10 comes with a trimmable Arm-to-Vest Connector, whereas the Smooth Shooter's Arm-to-Vest Connector is not trimmable.
