DiveVolk SeaTouch 4 Max Plus Ocean Kit for Underwater Photography – Red Filter & Wide-Angle Lens Bundle

The front of the housing is a patented flexible membrane that presses directly onto your phone's screen, so you operate the phone's own native touchscreen with your fingers — there are no physical buttons or levers at all. Any camera or dive app works, since you are simply using the phone normally through the membrane. One setup note: on iPhone enable 'Raise to Wake,' and on Android turn off 'Mistouch Prevention' and set the screen timeout to Never, so the display stays awake through the dive.

The housing is waterproof to 60 meters (200 feet). DiveVolk rates reliable touchscreen sensitivity to 30 meters (100 feet), so plan your touch-based shooting within recreational depths. It is slightly negatively buoyant — it sinks gently rather than floating away — so a float or lanyard is a smart addition if you set it down underwater.

It fits phones up to about 180 x 82.5 x 11.2 mm with a camera bump no thicker than 15 mm — which covers most current iPhone and Android flagships — and the Max Plus has extra internal room that adds support for the iPhone 16 series. Our listing includes the iPhone adapter, which centers your phone's camera in the housing; other phone models use a specific 3D-printed adapter. Note that adapters are not interchangeable between the different SeaTouch housing versions, so match the adapter to the Max Plus.

The Ocean Kit builds the housing into a wide-angle photo rig: it adds a 67mm lens adapter with an expansion clamp for mounting, a 67mm red filter to restore color lost underwater, a 0.6X underwater wide-angle conversion lens for dramatic reef and big-animal shots, a protective cover, and a travel case. It is the fastest way to go from phone-in-a-housing to serious underwater wide-angle photography.

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.
