Whether you’re looking to capture the moment on an upcoming holiday, dive, or family snorkelling trip, or planning to commit to underwater photography as a more serious hobby, having the right tools is key. A dedicated underwater camera can be handy if you’re keen to have a dedicated image capture device, but it’s often more convenient to use something you’re more familiar with. This is where an underwater phone housing can change the game.
Imagine you could simply take your own phone underwater and snap away without fear of causing some serious damage. An underwater phone housing lets you do exactly that, offering greater protection and functionality at depth than a simple phone case. There are lots of different underwater phone housing options available, with Sealife leading the way in terms of technical specifications and innovation. In fact, their latest creation, the new Sealife Sport Diver S Underwater Phone Housing, is already one of our top underwater phone case picks.
To celebrate the launch of the Sealife Sport Diver S Underwater Phone Housing and explain why this clever tool could be the perfect way to take your underwater photography to the next level, we’ve outlined the key features in this blog.

Ergonomic Design
From first use, it’s easy to see that the Sealife Sport Diver S underwater phone housing has been designed to make use below the surface as easy as it should be. It’s an incredibly lightweight device, so you need not worry about feeling like your phone is suddenly ten times heavier. A large shutter lever and responsive rear control buttons also ensure that every function is within easy reach, even when you’re wearing thick dive gloves. It’s this carefully considered and ergonomic design that highlights why an underwater phone housing can be a genuine pleasure to use, allowing you to stay focused on the shot rather than fumbling with fiddly buttons.
Tough & Reliable
Reliability is absolutely everything if you’re taking your smartphone underwater. Fortunately, the Sealife Sport Diver S certainly provides peace of mind on this front as it’s engineered to withstand depths of up to 30 metres with a polycarbonate, stainless steel, aluminium and optical-grade glass construction. Inside, your phone is held securely by a spring and rubber grip that adds additional shock protection, while ‘Dual Leak Alarms’ also give you a warning should the seal ever be compromised. Add in the robust TPE O-ring and cam-lock sealing latch and you have one of the most reliable underwater phone housings ever constructed.
Great Compatibility
One of the biggest advantages of using a Sealife underwater phone housing is versatility, with the SportDiver S compatible with a range of different devices. It works with all iPhones from iPhone X and up, including all Pro Max Models, as well as most Android smartphones. This wide compatibility means you don’t have to worry about switching housings if you upgrade your phone or are sharing between different members of the family.
Handy App
Rounding out the Sealife SportDiver S’ selection of great features is a free app which pairs seamlessly with the housing. Once installed, you can switch quickly between photo and video modes and make the most of your phone’s native camera technology. The app gives you full creative control, with options to adjust zoom, exposure, focus, white balance, and aspect ratio. It even allows you to shoot in high-quality formats such as 4K, RAW, and JPEG. This means you’re both protecting your phone and unlocking its full potential as an underwater camera - a win-win.
The best part is that you don’t have to wait to get your hands on this awesome underwater phone housing.
