Invisible Dive Case for Insta360 X3

The eForChina Invisible Dive Case is a transparent waterproof housing built specifically for the Insta360 X3 action camera. It uses a real-machine mold opening for a precise fit and a unique optical spherical lens made from PMMA. The lens delivers 95% light transmittance, rising to 98% with an AR anti-reflection coating. A hardened PC shell adds scratch resistance and a textured anti-fingerprint finish.

For 360° underwater creators.

This case suits divers, snorkelers and swimmers who need 50-meter waterproof protection and 360-degree total invisibility to capture seamless panoramic stitching below the surface. The amorphous silica gel seal and 304 stainless steel hinge and buttons are built for repeated immersion. Buyers who only shoot on land or who need a slim everyday cover will find the dive-rated bulk unnecessary.

Snap-fit assembly with supplied tools

Installation uses the included long screw and small wrench to secure the camera via the invisible adapter, while the flip-case design allows quick opening once the screw is set. The 5H surface hardness resists scratches during handling, but the PMMA lens must be cleaned with the supplied alcohol packs before each dive to maintain 98% transmittance. Over-tightening the stainless steel screw can damage threads, so hand-tighten only.

Questions about this item

What camera must I already own for this case to fit?

The case is moulded for the Insta360 X3 action camera and includes an invisible adapter that locks the camera inside the housing.

Will my existing Insta360 X3 lenses stay clear at 50 m depth?

The PMMA spherical lens has 95 % light transmittance, rising to 98 % with the AR coating, and the AS hard film resists scratches and fingerprints at depth.

How can I verify the seal is sound before I dive?

Close the hardened PC shell, check that the amorphous silica-gel ring sits flush, then submerge the empty case and watch for bubbles around the 304 stainless-steel hinge and buttons.
