What’s up Legends — we took the Insta360 X3 out for a proper underwater test in Sardinia, Italy, because we’ve been chasing that truly seamless 360 look for ages. If you’ve ever used the regular Insta360 dive case, you’ll know the pain: the stitching is way better underwater, but there’s still that tiny bit of case that just refuses to disappear in the final footage. Insta360 says their new Invisible Dive Kit (with the Invisible Dive Case) fixes it, so we didn’t want to take their word for it—we got in the ocean and tested it for real. In the video we break down why a dive case matters even though the X3 is waterproof to 10m (33ft): it’s all about light refraction—air and water bend light differently, and that messes with the stitching algorithm. The big takeaway is technique: to get that “invisible selfie stick” effect underwater, the camera (and case) must stay perpendicular to the selfie stick. If it bends, you’ll see it, and the whole invisible effect falls apart. We also cover quick FAQs like compatibility (X3 only), that it’s designed for underwater (not as an above-water protective case), and how to rinse/soak it in fresh water after saltwater sessions to keep it lasting.
