The Steadicam Curve for GoPro HERO Action Cameras (Red) CURVE-RD is a perfect gimbal-based handheld stabilizer for GoPro HERO, HERO2, and HERO3 action cameras. It aids in avoiding the shake and vibration during hand held shooting of action video. It needs the LCD BacPac for proper balancing. With the balance system in place, you can take smooth shots of action and adventure without restricting the range of movement. It helps in reducing the motion-induced "jello effect" or wobbly, distorted video. The handle tucks away beneath the camera mount making it convenient for portability.
