1.40M Diving Case: Features a waterproof seal and tightened buckle; the rugged waterproof housing shell helps prevent water leakage effectively. 2. HD Scratch-Proof & Clear Shooting Underwater: The lens is made of super clear optical glass; glass lenses are more transparent than ordinary plastic lenses, delivering clearer and more detailed shots, and they protect your camera lens from scratches. 3. Upgraded Quick Release Buckle Mount: Includes a quick release buckle mount and screw; you can attach your camera to accessories such as tripod, bicycle mount, and suction cup mount. 4. Protective: Protects against flying debris, gravel, dirt, and small rocks; provides full protection in cold environments or high pressure underwater for your camera. Use scenarios: - Snorkeling or shallow diving to 1.40 m for underwater photos or videos. - Mount on a tripod for stable landscape or macro shots, or on a bicycle mount or suction cup mount for action footage. - Outdoor shoots in dusty, windy, or cold environments where debris protection is needed.
