This is a ruggedly built gooseneck with protective covering that expands the versatility of your GoPro camera (compatible with all models). Clamp your GoPro to objects ranging in size from .25" to 2" (.6cm to 5cm) in diameter. Attach your camera directly to the clamp for low-profile mounting, or use the optional neck to achieve a wider range of camera-angle adjustability. Jaws securely grips irregular shapes and super slim objects thanks to its innovative design.
