Waterproof case can be used by directly installing the camera, which is convenient and fast, and the waterproof effect is better. AFAR double layer optical coating and toughened glass are used to make the lenses more transparent and easier to clean. The lens also eliminates the risk of scratches, so it can restore the natural light and color in both shooting and daily protection. Shell body is made of acrylic with high light transmission, compression resistance and no deformation. It can effectively waterproof 60 meters deep and the metal and buttons on the waterproof shell are made of 316 stainless steel, which is more corrosion resistant. Aircraft screws are configured to be easily tightened and loosened for easy use.
