Glidecam Devin Graham Signature Series Hand-Held Stabilizer - combines features of their HD-Series stabilizers with many professional features from more elaborate body-mounted systems to transform your shaky handheld footage into smooth, graceful shots. Its precision camera balance platform incorporates a quick-release, sliding dovetail plate that lets you quickly attach or remove your camera, and features fine-tuning control knobs that enable precision front-to-back and side-to-side adjustments for horizontal balancing. Further aiding balancing is a 1" diameter telescopic center post with laser engraved guide markings and a position-adjustable gimbal for quick vertical balancing. Rounding out the system is the dynamic base platform that supports the included counterweights and can manually expand or contract, allowing you to adjust the system dynamic balance and rotational pan inertia of the system.
