The 3/4" Steadicam Arm Post & Vest Adapter for Motorized Gimbals and Steadimate System helps take the weight of your motorized gimbal from the operator's arm and transfer it to your body, allowing you to avoid fatigue and shoot for a longer duration. Attach the adapter to your motorized gimbal, balance, and mount on your arm and vest system. The adapter allows you to use your gimbal on a variety of vest/arm systems with a 3/4" mounting pin. It is compatible with motorized gimbals with handlebars 25, 25.5, or 30mm in diameter.
