TelesinTelesin Underwater Diving Phone Case – 20m Waterproof

Take your smartphone beneath the surface with the Telesin Underwater Diving Phone Case. Designed for compatible straight-screen phones measuring 5.4–6.9 inches, this underwater housing combines a manufacturer-specified 20-metre depth rating with Bluetooth camera controls, a textured grip and a vacuum pump for pre-dive seal checks.

Whether you are photographing a reef or recording holiday snorkelling footage, the external buttons let you operate supported camera functions without touching the enclosed phone's screen.

Key Features

• Manufacturer-specified IP68 waterproof housing for depths up to 20 metres.
• Designed for compatible 5.4–6.9-inch straight-screen smartphones.
• Five external buttons for supported shutter, zoom and mode functions.
• Bluetooth connection to the enclosed smartphone.
• Lens with a stated 97% light transmittance and an anti-fog design.
• Supplied vacuum pump for checking the seal before use.
• Adjustable foam padding to help position the phone securely.

Smartphone Compatibility

The manufacturer lists straight-screen smartphones with 5.4–6.9-inch screens, including iPhone 14, 15 and 16 series, Samsung Galaxy S23 and S24 series, and Google Pixel 8 series. Screen size alone does not guarantee a fit: check the manufacturer's guidance for your exact model before purchasing.

Adjustable foam padding helps centre the phone inside the housing. A thin phone case may fit, but curved-screen phones, thick cases and PopSockets accessories are not supported. Available camera controls depend on the phone and software.

Underwater Camera Controls and Lens

The five-button layout provides a capture button, two zoom buttons and two mode buttons. The grip keeps these controls within reach while your phone stays enclosed. Test the supported functions with your phone before entering the water.

The high-transmittance lens allows light to reach the phone's camera, while the anti-fog design is intended to reduce condensation. Follow the manufacturer's preparation instructions; neither feature guarantees fog-free or unchanged image quality in every condition.

Setup and Pre-Dive Checks

1. Inspect the housing, seals and closures for dirt, obstructions or damage.
2. Position your compatible phone using the foam padding and close the housing according to the manufacturer's instructions.
3. Perform the manufacturer's seal-testing procedure using the supplied vacuum pump before underwater use.
4. Hold the capture button for two seconds to power on, then select TELESIN_SDC in your phone's Bluetooth settings.
5. For iPhone, the manufacturer's setup graphic also instructs users to enable Zoom under Settings > Accessibility > Zoom. Follow the supplied instructions for your device.
6. Test the controls and confirm the housing is correctly sealed before entering the water.

Always follow the manufacturer's operating and depth limits. A successful vacuum check does not guarantee against leakage, and the waterproof rating does not remove the risk of water damage.
