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

Absolutely love this housing

By Roy
Rated 5 out of 5
Date: 2025-10-04

My wife purchased this phone housing for me as a gift. I was a bit skeptical at first and it seemed like a lot of work to make it functional but the learning curve is small. After a couple of trips it’s automatic and you learn a couple of work arounds. This housing allows you to take much better pictures and videos than a go pro and the pictures don’t go to Gopro heaven to never be seen by anyone ever again. Absolutely love this housing, in fact so much I’m buying her one as well. BTW my phone has never overheated and we routinely dive in Bonaire and Belize.

Great idea, horrible implementation

On paper this is a great product. Universal phone compatibility, moisture detection, vacuum leak detection, etc. Sound amazing, right? I was excited about it, and it looked good upon initial testing at home. Switching between photo and video is pretty clunk because it requires you to scroll through playback and settings modes (always!!!), but otherwise it seemed to work well. Vacuum pump is included, buttons control phone through bluetooth via an app, so no physical button connection, etc. Unfortunately in practice the product is horrible. First of all, my phone always overheats because you normally dive in hotter climates (Mexico, Bahamas, etc.) and the app keeps the phone on the entire time. It does turn the screen off, but it still manages to overheat very often. Once the phone overheats, the app is shutdown, and there is nothing you can do - the case and the phone are unusuable without opening the phone. Moreover, the phone always things there is a leak even if there isn't one when used outdoors. The manual says it's the changes in the pressure caused by case heating up that makes it think there is a leak (or something like that). So when you test the case indoors with vacuum pump, it's great. When you try to use it outdoors before the dive, it things there is a leak and starts beeping. It beeps non-stop and I had other divers get very annoyed by it (not even mentioning how annoying the non-stop beeping is to me). There will be not a drop of moisture inside the case, but the case decides it's leaking and it beeps non-stop anyway... So three main issues: 1. Clunky user interface through the app which requires 3-4 button presses to switch from photo to video mode 2. Phone always overheats because the app keeps it on 3. Case always thinks it's leaking and it beeps non-stop. Unfortunately now there is no way for me to return the case. I find it absolutely unusable.

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.
