SeaLife SportDiver S Underwater Smartphone Housing
The SeaLife SportDiver S lets you take a compatible smartphone underwater for photos and video. Its shutter lever and rear buttons control the free SportDiver app, giving you a practical way to capture images without touching the phone screen.
Features and benefits
- Physical camera controls: switch between photo and video and adjust the settings supported by your phone, including zoom, exposure, focus, white balance and lens selection.
- Pre-dive vacuum analysis: checks pressure retention before entering the water. After a successful analysis, the vacuum-pressure alarm stops; the moisture sensor provides visual leak alerts if water reaches it underwater. Inspect the seals and complete the pre-dive test every time.
- Optical-glass lens port: provides the camera’s viewing window.
- Bluetooth connection: links the housing controls to the phone through the app.
- Capture and playback: supported phones offer RAW/JPEG photos and 4K video. Playback mode lets you review photos and videos through the housing controls, and files also save to your phone’s Photos app. Available settings depend on your phone and app support.
- Phone support: a holding spring and interchangeable rubber grip tabs keep the phone positioned. Choose the tabs to suit your phone and keep them clear of its side buttons.
- Moisture Muncher: the capsule absorbs humidity inside the sealed housing to help reduce lens fogging.
- Accessory mounts: let you add compatible trays, underwater lights and lens accessories.
Check your phone before ordering
Check your exact phone against the SeaLife SportDiver compatibility guide and select the S housing. Download the app to check which camera controls your phone supports. Phone size, camera layout and app support all matter.
What is included?
Housing, vacuum pump, grip tabs, spare seal set, lubricant and removal tool, wrist strap, Moisture Muncher sample, two AAA alkaline batteries and travel pouch. Phone, lights and colour-correction filter are sold separately.
Care, rinsing and storage
Follow the manual’s seal inspection and vacuum-test instructions before each use. After diving, soak the closed housing in fresh water for about 20 minutes and press each button 20 times. Dry yourself, the housing and the vacuum-port area completely before releasing the vacuum or opening the door.
Use the specified SeaLife lubricant and replacement seals. Keep sealing surfaces free of sand, hair and grit. Avoid household cleaners and spray-on sunscreen. Store the clean, dry housing with its door unlatched and slightly open, away from heat.
