Underwater imaging used to sit between two extremes: tiny action cameras on one side and bulky professional rigs on the other. We’ve come a long way from basic Nokias and Motorolas, and the cameras in our cell phones are extremely capable nowadays. So why not take them underwater? Modern phone housings make that possible.Now, phones can fill the space in between, offering more control and better photos than many action cams. They’re also far cheaper and easier to travel with than a full camera rig. In this guide, we’ll look at what really matters when choosing a phone housing: underwater usability, editing options, ability to expand, leak protection, and even apps.
We’ll use five popular examples; not to rank them, but to show how different designs solve the same problems in different ways.
- Divevolk Seatouch 4 Max Plus
- Divevolk Seatouch 4 Max Platinum
- Oceanic+ Dive Housing
- Oceanic Sport Housing
- SportDiver S Smartphone Housing
By the end, you should have a clear sense of where phone housings sit compared to action cams and “big camera” housings, and which type of system best fits the way you actually get in the water.
Phone Compatibility
Phone compatibility is one of the biggest hidden gotchas with underwater housings. Some housings are designed around very specific phone dimensions or only work with certain systems (e.g. Apple vs. Android). That tight fit is great for camera alignment and a snug, rattle-free feel, but it can be limiting if you later change phone size or switch brands.
Oceanic teamed up with Apple to create the unique Oceanic+ ecosystem on Apple Watch Ultra, and so all things Oceanic are Apple. That Apple focus continues into its phone housings, as both the Oceanic housings are iPhone-only. Both have adjustable spring tabs that line up with your iPhone and hold it firmly in place. With the Oceanic+ Dive Housing, you shoot through the Oceanic+ app, which links the housing’s buttons directly to on-screen functions (we’ll come back to app vs. manual shooting later). If you’re an Android owner, the Oceanics are a no-go.
Spring-Adjustable Tabs
The SportDiver and Kraken are very similar here, and use the more universal spring-tab system. They both support a broad range of iPhone models and many popular Android phones, as long as they fall within a certain size window and are removed from any bulky case.
Tray-based Compatibility
On the Divevolk housings, the phone sits in an internal tray or adapter inside that holds it firmly in place. This positions the screen against the front membrane, so different phone models can still line up correctly with the touchscreen. Each adapter fits a small family of phone models, so if you upgrade to a different size or shape, you may only need to buy a new adapter (usually around $20–30) instead of replacing the entire housing.
→ How the phone is held matters for future upgrades. Some housings are locked to iPhone only (Oceanic), while universal spring-tab designs (SportDiver, Kraken) and Divevolk’s adapter-based systems support a wider mix of iPhone and Android models within certain size limits.
Ergonomics and Underwater Usability
So, now that you know which housing will actually fit your phone, the next question is: how do you want to use that phone underwater? There are two main usability styles. Some housings work through a dedicated app and physical buttons, which “lock” you into that camera app while you’re underwater.
Others use a soft membrane front, so divers can operate the touchscreen almost exactly as they would on land, switching between apps and controls directly on the phone’s screen.
Touchscreen Membrane
This is the signature feature of the Divevolk Seatouch 4 Max Plus and Divevolk Seatouch 4 Max Platinum. The front membranes are designed so your phone behaves much as it does on land.
You swipe, tap and change apps through a pressure-sensitive front, which is great if you like jumping between the camera, note-taking underwater ID apps, or even making a call at the surface.Now, if you install a 3rd-party app, like Blackmagic cam, you can take full advantage of your phone’s camera and not be tied to a single housing app.
Body Build
The Divevolks are essentially rectangular bodies with a flat face for the touchscreen membrane and simple controls or latches around the edges. They are made of aluminum alloy and plastic, and their boxy shape makes them easy to stash.
However, their flat surface doesn’t give you a sculpted grip. They operate at their best with the screen front and center, both hands bracing the housing as you tap and swipe. Many divers choose to attach their Divevolk to a tray for easier underwater handling.
The Oceanic+ Dive Housing and Oceanic Sport Housing lean much more into a “grab-and-go” camera feel. The Oceanic+ Dive Housing in particular has a solid, moulded body with an integrated grab handle and a layout that naturally puts your hand in the right place, so it feels secure even in chunky gloves or mild current.
Together, the Oceanics and SportDivers are ergonomically more “camera-shaped,” while the Divevolks are more “housing-shaped.” Which you prefer will come down to whether you like a grip-first or screen-first feel underwater.
Designated Housing App
In contrast to membrane-style housings, the Oceanic+ Dive Housing and SportDiver S Smartphone Housing are driven by their own designated apps, which act as the “brain” of the system. You use large mechanical buttons or a shutter lever, and those controls are mapped to specific functions inside the Oceanic+ or SportDiver app.
This makes the experience feel like a familiar compact camera. You get clear feedback, fewer accidental presses, and a simple, consistent interface on every dive. With Oceanic+ Dive Housing, you can also choose to opt into the paid subscription so the housing also functions as a dive computer.
The flip side is that you’re essentially locked into that app while you’re underwater, rather than freely jumping between different apps.
→ If you prefer that more traditional camera shooting style, choose the Oceanic+ Dive or the SportDiver. Having a grab handle and a shutter button will feel more natural underwater.
→ If you want the freedom to access all your phone’s apps and functions, then go for the membrane-front of the Divevolks. However, these frames are less ergonomic and divers might want to invest in a tray for easier handling underwater.
Editing: On the Dive and After the Dive
Now you’ve wrapped your head around how you’ll control the housing, the next question is how much effort you’re willing to invest. Some housings are designed so that color corrections happen live as you shoot.
Other housings assume you’ll do the tweaking later, back on the boat or at home on a bigger screen. Neither is right or wrong; it’s just about whether you want quick, shareable results, or flexible files you can spend more time on later.
In-App Color Correction
With the Oceanic+ Dive Housing, the idea is that a lot of the heavy lifting happens in the Oceanic+ app while you’re underwater.
You’re shooting through a dedicated interface that will apply underwater color correction, overlay dive information, and give you files that already look pretty close to finished when you climb back on the boat. It’s a very “shoot, review, share” kind of experience, tailored to divers who don’t like to fiddle too much after a dive.
The SportDiver S Smartphone Housing leans slightly more toward capture control than heavy in-app editing, but the feel is similar. You set white balance, exposure, and focus in the app, take the shot, and you’re most of the way there. For many recreational divers, especially those shooting for social media, this approach is more than enough.
Third-Party Apps and Manual Control
The Divevolk Seatouch 4 Max Plus and Divevolk Seatouch 4 Max Platinum sit at the other end of the spectrum. Because of the touchscreen membrane, you’re not tied to a single housing app at all—you can run your native camera, a manual camera app, a logbook app, and even on-phone editors if you really want to. You can adjust settings in a pro camera app during the dive, then do a rough edit in a mobile editor during your surface interval. If you like to edit and tinker with footage, the Divevolk’s flexibility will be more fun for you.
The Oceanic Sport Housing can work both ways. Since it is part of the Oceanic ecosystem, you can choose to use the Oceanic+ app for in-app edits. But since the Oceanic Sport has a membrane screen, you can also opt to just use it as a regular phone inside a shallow-water housing.
→ If your goal is to shoot, glance at, and share your images that evening, then app-driven systems like Oceanic+ Dive Housing and SportDiver S are very comfortable. The apps do most of the editing, but you can do some light touch-ups if you desire.
→ If you like the freedom to do things your way, the Divevolk front screen access lets you capture flatter, more flexible files and push them further in your favorite editor later—closer to the mindset of shooting RAW with a DSLR.
Apps and their Subscriptions
We’ve already discussed apps, but what we haven’t touched on is that you may need to pay for some. Some housings are built around a designated app while others are totally open, and on top of that you might still want separate apps for editing, fish ID, or logging.
Oceanic+ Ecosystem
For the Oceanic+ Dive Housing, the Oceanic+ app is the heart of the system. On the free tier, it acts as your underwater camera with live color correction, basic depth and time information, and a simple logbook. If you decide to pay for the subscription, Oceanic+ unlocks full dive-computer features (NDL, deco tracking, planner, alerts) and ties your dives, photos and videos into one integrated logbook that can be shared across Apple Watch Ultra and iPhone.
The Oceanic Sport Housing can also plug into this ecosystem: you don’t have to use Oceanic+ app, but if you do, you get the same color tools and logging benefits for your snorkel and shallow-water shots.
SeaLife SportDiver S
The SportDiver S Smartphone Housing takes a different approach. SeaLife’s SportDiver app is free, doesn’t require an account and doesn’t involve any subscription. It’s there to give you camera control (exposure, white balance, RAW/ProRAW on supported phones) and simple playback, and that’s it.
Open App Choice with Divevolk
The Divevolk Seatouch 4 Max Plus and Divevolk Seatouch 4 Max Platinum don’t tie you to any single app at all. Thanks to the touchscreen membrane, you can use your phone’s native camera, a pro manual camera app, your favorite editing app, a fish ID app, notes etc.
If a better camera or editing app comes out next year, you can just install it and go diving. The trade-off is that you’re responsible for your footage rather than having one “official” app that does everything.
Apps Worth Considering
Regardless of housing, there are a few app categories most divers end up using:
- A manual/pro camera app (if your housing allows it), for more control over exposure, focus and color
- A photo/film editor like Lightroom or Capcut for quick tweaks between dives
- A fish ID or marine life guide app, like LinneLens, which pairs nicely with touchscreen-friendly housings like the Divevolk or Oceanic Sport
→ If you like the “one app-to-rule-them-all” experience, the Oceanic+ Dive Housing is built for you, with the option of a subscription for full dive-computer features. → If you prefer free, simple and focused, the SportDiver S app gives you solid camera control with no ongoing costs. → If you want to build your own studio of camera and editing apps, the membrane-based Divevolk housings and Oceanic Sport Housing give you maximum freedom to pick and change apps as you go.
Add-ons & Accessories
Lights, trays, filters, and remote shutters can turn a simple shell into a proper little imaging rig. Here’s how that looks for the Oceanic, Divevolks, and SeaLife SportDiver.
Oceanic
The Oceanic+ Dive Housing is built to play nicely with standard underwater video accessories. It has a 1/4″-20 style mount so you can bolt it onto camera trays with dual handles and ball joints, then add video lights on arms just like you would with a compact or mirrorless rig.
Many shops sell it bundled with a BigBlue or similar tray + light package, giving you a ready-made two-handed video rig straight out of the box.
Because the housing relies heavily on clear optics and a dry interior, Oceanic also offers spare-part kits with extra O-rings, grease, desiccant and rubber pads so you can keep the seal and anti-fog performance in good shape as you dive more.
Filters are typically handled at the light level (red or yellow filters on the video lights themselves) rather than as clip-ons for the housing port, and the Oceanic Sport Housing can use a similar tray-and-light setup if you want to upgrade a basic snorkel shell into a more serious shallow-water video rig.
Divevolk
The Divevolk ecosystem is very modular, especially around the Seatouch 4 Max Plus and Seatouch 4 Max Platinum. This is where the big difference between these two housings stand out. The Seatouch 4 Max Platinum has mounting points and a lens adapter built into the housing, whereas the Plus needs an extra bracket clamp to be able to add a tray.
You can add a single- or dual-handle tray to give yourself a more stable grip and space to mount video lights. Divevolk (and other companies) offers expansion clamps with integrated 67 mm lens adapters so you can screw on wide-angle or macro wet lenses and red filters directly in front of the phone’s camera, just like a small DSLR rig.A particularly nice upgrade is the Divevolk Underwater External Shutter, which connects via bluetooth, so you can shoot via physical shutter lever to get a more camera-like feel.
SeaLife SportDiver
The SportDiver S Smartphone Housing taps into SeaLife’s long-running Flex-Connect system, which is basically lego for underwater cameras. You can snap the housing onto single or dual trays, add one or two Sea Dragon video lights or strobes on Flex arms, and rearrange everything with ball joints and adapters as your needs grow.
On the optics side, SeaLife offers 52 mm and 67 mm lens adapters specifically for the SportDiver, plus magenta and yellow filters that help color-correct in different water types when you’re not using lights.
There’s also a whole catalog of “support” accessories: spare O-rings, moisture-absorbing capsules, screen shields, float straps, and travel cases to keep the housing safe between dives. Altogether, the SportDiver system is very much designed to grow with you from a simple phone-on-a-tray to a proper dual-light, lens-enhanced rig without changing brands.
Common Pitfalls
If you have made it this far, and are seriously thinking about buying an underwater phone housing, then there are definitely some things you should consider first.
First, remember that you are going to use your phone. Our phone isn’t just a telephone device, but where we check in with loved ones, read our emails, have our hotel bookings, flight tickets, our wallet—basically our entire lives.
If we lose our cell, especially in a remote location, it could be problematic. With proper pre-dive preparations, the likelihood of these housings flooding is low. However, we recommend having all your important information written backed up, just in case.
From that, check if your insurance will cover floodings and is able to help if your housing leaks. There is peace of mind knowing that if things do go south, at least you’re covered.
Second, the Divevolk Plus and Divevolk Platinum can be affected by thick screen protectors, or certain gloves. If you already have a thick screen protector on your phone, you will be better off with the button-based housings. SportDiver S Smartphone Housing and Oceanic+ Dive Housing use physical controls mapped to specific functions.
- Double check if your insurance can cover water damage to your phone
- Backup all important information in case your phone does get flooded in the housing
Final Thoughts
Now that our mobile phones have serious cameras, they have become a genuine third option between action cams and full camera rigs. Compared to action cams, these housings offer better still-photo potential and creative control. Compared to DSLR or mirrorless rigs, they drastically reduce cost, weight and complexity.
The Divevolk Seatouch 4 Max Plus and Divevolk Seatouch 4 Max Platinum appeal to divers who want an “underwater smartphone” with full app access and, in the Platinum’s case, strong support for add-on optics and trays.
The Oceanic+ Dive Housing suits divers who like a tightly integrated system where camera, dive computer, and logbook live together.
The SportDiver S Smartphone Housing offers a compact, neutral-buoyancy rig with a free app and strong compatibility with lights and trays.
Take a moment to look at this.
