With the Puluz Waterproof Case, you can take underwater pictures with the Insta360 X3 camera at a depth of up to 50 metres. It is made of highly translucent plastic - the lens material is PMMA with a light transmission of 95%, which reaches 98% after the application of an anti-reflective coating. Thanks to the unique housing design, all dead zones have been eliminated. The surface has a hardness of 5H, comparable to ordinary glass, and is therefore resistant to fingerprints and scratches. In addition, the metal parts are made of 304 stainless steel, so you don't have to worry about corrosion.
