【Compatibility】Go Pro Hero 13/12/11/10/9 Black. 【Enhance Underwater Stability】The buoyancy of the floating frame can offset some of the weight of the camera in the water, reduce the shaking caused by water flow or shooting movements, especially in environments with strong water flow, which can significantly improve stability. 【Anti Sinking Protection】Even if the camera accidentally gets out of hand, the buoyancy frame can prevent the device from sinking to the bottom of the water, reducing the risk of loss. 【Portable&Easy To Operate】Compared to traditional metal counterweights, buoyancy materials are lighter, easier to carry and install, and suitable for travel or outdoor photography. 【Collision Buffering】The physical structure of the frame can absorb some impact and reduce damage when the camera collides with hard objects such as rocks and corals.
