No tools are required to assemble this new hand held stabiliser. Screw in the expandable post to the lower strut, and do the same with the counter weight. Screw in the quick release plate onto your camera, and lock it onto the Ultra-Lite and you're ready to start shooting. The Quick release mount allows you to quickly detach your camera to mount it directly onto a tripod if needed , or just to store it away. The best part is, once you balance your camera, you'll never have to balance again! The Gimbal can rotate and tilt in just about any direction and still give a sense of floating. The Gimbal knob allows you to lock it in place for a single hand operation. The for and aft knob locks the camera in to view shooting, high or low. The post is also fully adjustable.
