Features and construction

45-metre waterproof housing

Designed for underwater use to a rated depth of 45 metres, the housing allows compatible DJI Osmo Action cameras to be used for diving and other water-based filming. Its integrated rubber-ring seal helps prevent water ingress when the case is correctly closed and maintained.

High-transparency polycarbonate shell

The housing uses polycarbonate material with a stated light transmittance of 95%. This helps maintain light transmission to the camera while providing a protective barrier around the device, supporting clear underwater images.

Tempered glass lens cover

The tempered glass lens cover provides a protective surface over the camera lens area. Its scratch-resistant construction helps guard against everyday abrasion and minor contact with sand or other surfaces.

316 marine-grade stainless steel buttons

The functional buttons use 316 marine-grade stainless steel for improved resistance to rust and saltwater corrosion. Their alignment with the camera's controls allows operation while the camera remains inside the housing.

Integrated rubber-ring seal

The rubber-ring sealing structure forms the main waterproof barrier around the housing. Checking the seal for debris, damage and correct positioning before each use helps maintain its protective performance.

Included anti-fog sheets

Temperature changes and trapped moisture can cause condensation inside a sealed housing. The included anti-fog sheets help absorb moisture and reduce fogging, helping keep footage clear during underwater sessions.

Why choose this waterproof case

• Protection for underwater filming: A housing rated to 45 metres provides a protective enclosure for compatible cameras during suitable underwater activities.
• Designed to preserve image quality: High-transparency PC and a tempered glass lens cover help maintain a clear optical path.
• Built for marine environments: 316 stainless steel buttons offer resistance to corrosion from saltwater exposure.
• Additional physical protection: The rigid shell helps protect the camera against impacts and contact with surrounding surfaces.
• Reduced risk of lens fogging: Included anti-fog sheets help manage internal condensation.
• Straightforward camera installation: Positioning grooves and a locking buckle support a simple installation process.

Ideal uses

• Scuba diving and underwater exploration

Installation and care

1. Open the housing using the locking buckle.
2. Insert the compatible camera, aligning it with the internal positioning grooves.
3. Close the rear cover and secure the buckle fully.
4. Before entering the water, inspect the housing, buckle and rubber seal for damage, debris or incorrect positioning.
5. After use in saltwater or brackish water, rinse the case thoroughly with fresh water.
6. Allow it to air dry in a cool, shaded, well-ventilated area before storage.

Store below 40°C in a cool, dry, well-ventilated place, away from direct heat.

Important: Always check the housing's seal and locking mechanism before use. Follow the manufacturer's instructions for installation, maintenance and depth limitations. The 45-metre rating should not be treated as a guarantee against leaks if the case is damaged, incorrectly sealed or improperly used.
