Oceanic+ Underwater Housing for iPhone – Scuba Dive Computer & Camera in One (Retrofit Installed)

Before every dive, open the housing somewhere clean and dry, inspect and wipe the main o-ring and its groove, and close it with nothing trapped in the seal, because a single hair or grain of sand is enough to flood it. Confirm every latch is fully closed and that any vacuum or leak alarm reads correctly. Where you can, soak the sealed housing in a rinse tank or hang at the surface before descending, so a leak shows up before depth.

Remove the main o-ring regularly with a plastic tool rather than anything metal, which can nick the groove, and clean both the o-ring and the groove with a lint-free cloth. Apply a thin film of the silicone grease the manufacturer specifies, since grease helps the o-ring seat and slide rather than sealing by itself, and a thick coat only collects grit. Replace o-rings on the schedule in the manual, or sooner if they look flattened, cut, or dry.

A moisture alarm is a sensor inside the housing that beeps or flashes when it detects water, giving you a chance to abort the dive before the camera is ruined. Desiccant packs absorb humidity in the air sealed inside the housing, which prevents the port fogging as you descend into cooler water. Neither replaces a proper seal check, since they provide early warning and fog control rather than leak prevention.

Only as deep as its rated depth, which the manufacturer sets and publishes in the specifications, and it should never be exceeded even briefly. Depth ratings assume a housing in good condition with intact seals, so worn o-rings or a damaged port reduce the real margin. If your diving might take you deeper, choose a housing rated comfortably beyond your planned maximum depth.

Only if the housing is specifically rated for the depth you plan to dive, because many phone cases are splash- or snorkel-rated rather than scuba-rated. Touchscreens generally do not respond underwater, so a diving phone housing needs mechanical buttons or another control method. A phone's own water-resistance rating is not a substitute for a housing, and any housing still needs seal checks and o-ring care.

Soak the closed, sealed housing in fresh water and work every button and dial while it is submerged so salt does not dry inside the control shafts. Let it dry completely, especially around latches and seams, before you open it, since opening a wet housing drips water straight onto the camera. Avoid opening a housing on a wet, moving boat deck whenever you have the option to wait.

Get the housing out of the water and open it somewhere dry, then immediately remove the camera's battery and memory card, because leaving a battery in a wet camera does more damage than the water itself. Do not power the camera on to check whether it still works. Dry everything gently away from direct heat, get salt-water-exposed equipment to a repair technician promptly, and inspect the housing to find which seal failed before you dive it again.

Oceanic lists the iPhone 16, 16 Plus, 16 Pro and 16 Pro Plus, iPhone 15, 15 Plus, 15 Pro and 15 Pro Max, iPhone 14, 14 Plus, 14 Pro and 14 Pro Max, iPhone 13, 13 Mini, 13 Pro and 13 Pro Max, iPhone 12, 12 Mini, 12 Pro and 12 Pro Max, iPhone 11, 11 Pro and 11 Pro Max, iPhone SE (2nd and 3rd generation), and iPhone Xs, Xs Max and XR. iOS 18.1 or newer is required, and the iPhone 16 Pro Plus needs a retrofit kit, which is already installed on this unit.

The housing ships with a spares kit containing 5 desiccant packets, a grease pack, an O-ring with an O-ring tool, and 2 rubber pads, so you have the service items needed to seal and maintain it. Call 888-701-4017 if you need a replacement part sourced.

The housing runs on its own rechargeable lithium battery, charged through USB-C using the included cable. The housing communicates with the phone over a Bluetooth electronic interface. Oceanic does not publish a watt-hour figure for the battery in the specifications we can verify, so check the manual for travel documentation.

Yes. With the Oceanic+ app it shows real-time depth in feet or meters, elapsed dive time, no-decompression time (TLBG), ascent rate through a variometer, and customizable safety warnings with haptic alerts. It supports nitrox up to 40% oxygen with PPO2 and CNS monitoring, logs dives automatically with temperature and ascent rate graphs, and calculates 24-hour no-fly time. It can also serve as a backup alongside an Apple Watch Ultra on the same Oceanic+ subscription.
