SeaLife Sportdiver Ultra Overview

From Manufacturer

Compatible with more phones than previous models and featuring a horizontal window for phones with multiple lenses, the SeaLife SportDiver Ultra Underwater Housing for Smartphones lets you take photos and shoot video of the action beneath the waves. The SportDiver Ultra uses the free SportDiver app to operate your phone's camera via Bluetooth, with physical buttons and levers for shutter operation, playback, focus, and zoom, along with advanced camera settings. The housing protects your phone in two ways: a vacuum pump verifies the integrity of the seal before you dive, and a moisture detector will alert you in the unlikely event of a leak during the dive. Seven 1/4"-20 threads allow mounting on a tray or tripod and attaching lights and accessories.

Controls and Handling
  • Operates phone via Bluetooth and SportDiver app
  • Access to advanced camera settings, including zoom, exposure (EV), auto/manual focus, white balance, tint, lens selection, RAW+JPEG mode, photo + 3-second video, and background blur (on multicamera phones)
  • Large shutter and control buttons can be operated while wearing dive gloves
Construction Details
  • Leak Avoidance System: A pre-dive pressure analysis gives you confidence that the underwater housing is 100% airtight and waterproof before entering the water. In the unlikely event of a leak while underwater, a secondary wet sensor alerts you of any water entry.
  • Sealed electronic circuitry protects against damage from accidental water drops entering the housing when opening after diving.
  • The landscape-oriented optical glass lens port with antireflective coating accommodates most multi-lens phones, including the Samsung Galaxy S24 Ultra. Ultrawide lens settings will not vignette.
  • The included underwater color-correction filter restores natural underwater colors. Filters for green algae water and UW fluorescence imaging are also available (sold separately).
  • The free SportDiver camera app ensures your privacy with no monthly subscription or in-app advertising. No email or phone registration is required, and SeaLife does not collect any personal data.
  • The app's Playback mode shows full-size photos and videos with a vertical thumbnail strip to easily locate your shots. Videos start playing automatically when selected. All files are also saved to the phone's photo app.
  • The housing automatically connects to your smartphone using Bluetooth Low-Energy BT5 wireless technology. No cables or buttons touch the phone, and power consumption is ultra-low.
  • A holding spring and rubber grip tabs securely hold the phone in place and add shock protection.
  • SportDiver Ultra is compatible with Sea Dragon underwater photo-video lights and underwater wide-angle/macro lenses.
  • Seven standard ¼"-20 tripod mounts allow for attaching underwater lighting or any tripod-mountable accessory.
  • The cam-lock sealing mechanism easily and securely locks the waterproof door.
  • Two AAA batteries provide over 50 hours of continuous use. AAA alkaline batteries are readily available no matter where your adventures take you.
  • The SL911 Moisture Muncher capsule prevents fogging.
  • Constructed of corrosion-resistant polycarbonate, stainless steel, and anodized aluminum, the SportDiver Ultra is depth-rated to 130', and each housing is individually depth-tested.

SeaLife Sportdiver Ultra Reviews

Not worth it

Amazon has a better return policy so you should buy this enclosure off there. You can’t take HDR photos with this case and app.

I'm writing a review because the only review was a 1 star review and that is definitely not our experience. I have an underwater housing for my Sony A6700 and a pair of very expensive photo/video lights. My daughter takes comparable photos with this SeaLife housing and her iPhone 14 with a single Sea Dragon 3000 light. With a little prep before the dive, preparing the phone to be dedicated to take photos, closing all the other apps and making sure you don't get other notifications on the phone that you can't clear once your housing is closed and pressurized - most conflicts will be avoided. We've not had issues with overheating and we dive in very warm water. We have photos that are worth 10X what we paid for this housing! When we get out of the water, the photos are ready to view, share, and edit, right on the phone and then they are saved automatically in the cloud moments later. My daughter doesn't want me to get one, because she loves getting a better picture with her phone than I get with a much more expensive setup. She's a dive master with over 200 dives. The SeaLife phone housing is legit.

Will this fit an Samsung S25 ultra?
Asked by: Rubens
The Samsung S25 Ultra is not included on the list of compatible smartphones; however, the S24 is and the difference in dimensions is negligible (S24: 162.3 x 79.0 x 8.6cm and S25: 162.8 x 77.6 x 8.2cm). Seeing as the SeaLife SportDiver Ultra Underwater Housing for Smartphones accommodates a wide range of different smartphones, it should still work with the Samsung S25 Ultra.
