Waterproof case Puluz PU890T for Insta360 X3 camera — protective housing for underwater use

The Puluz PU890T waterproof case is a sealed protective housing made for the Insta360 X3 action camera. It enables underwater shooting down to 50 meters while keeping camera controls accessible and protecting the device from water, splashes and moisture. The main lens window is made of PMMA with very high light transmittance and an anti-reflective coating to preserve image quality; metal parts use 304 stainless steel and the housing surface has a 5H hardness rating to resist scratches and fingerprints.

Advantages

The case offers reliable waterproofing to 50 m, a high-transparency PMMA lens window with AR coating for reduced reflections, and hardened PC construction for impact resistance. Corrosion-resistant 304 stainless steel fittings improve durability in marine environments, and included anti-fog inserts and cleaning cloths help maintain clear optics during extended use.

Suitable for

• Underwater photography and videography while diving or snorkeling
• Water sports such as surfing, kayaking, and paddleboarding
• Outdoor use in heavy rain, splashing conditions, or wet environments

When it may not be suitable

The housing is designed specifically for the Insta360 X3 and may not fit other camera models. It is intended for underwater recreational and professional shooting to the specified depth; activities involving extreme mechanical stress or impacts beyond normal use could exceed the case’s protective limits. Always verify compatibility with camera accessories that require external ports or connectors.

• Intended depth rating: up to 50 meters — confirm this meets your diving requirements
• Some external accessories or connectors may not be usable while the camera is inside the housing

Usage recommendations

Perform a leak test in shallow water before each dive, replace anti-fog inserts as needed, rinse all parts with fresh water after saltwater use, and avoid exposing the housing to strong impacts or sharp objects to maintain waterproof integrity and optical clarity.
