DIVEVOLK SeaTouch 4 MAX PLUS Underwater Housing with Included Adapter

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.

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.

The touchscreen membrane responds to your finger, so thick gloves will get in the way. DiveVolk makes a touchscreen finger cot designed for dry suit gloves that is compatible with the SeaTouch 4 Max series, which is the usual fix for cold-water divers. In warm water with bare hands or thin gloves, the membrane works as normal.

The housing itself is waterproof to 60 meters, but DiveVolk only rates reliable touchscreen sensitivity to 30 meters, so touch control gets unreliable deeper than that. If you regularly shoot deeper, DiveVolk makes an external shutter for the SeaTouch 4 Max series that gives you a physical trigger. Otherwise plan your touch-based shooting inside recreational depths.

That is a phone settings problem, not a housing fault. On iPhone, enable Raise to Wake; on Android, turn off Mistouch Prevention and set the screen timeout to Never. Do this before you seal the housing, because you cannot get to the settings once you are in the water.

Yes. The Ocean Kit adds a 67mm lens adapter with an expansion clamp plus a 0.6X underwater wide-angle conversion lens for reef and big-animal shots. DiveVolk also offers a +8 macro close-up wet lens in the same 67mm fitting for small subjects. Because both use the 67mm standard, you can swap between them on the same adapter.

A red filter restores the colour water absorbs as you descend, which is why the Ocean Kit includes a 67mm red filter. Without one, ambient-light photos go progressively blue-green with depth. It mounts on the same 67mm adapter as the wide-angle lens, so it is easy to fit and remove.

The Ocean Kit's expansion clamp is the mounting point, giving you 67mm adapter arms to build a rig around the housing. DiveVolk also makes an L bracket for the SeaTouch 4 Max that lets you shoot vertically or horizontally on a mount. Start with the clamp, then add arms and lights as your setup grows.

The Max Plus is the roomier version: it has extra internal space that adds support for the iPhone 16 series, on top of the general limit of about 180 x 82.5 x 11.2 mm with a camera bump no thicker than 15 mm. The important practical difference is that phone adapters are not interchangeable between housing versions, so an adapter bought for a SeaTouch 4 Max or Platinum will not fit a Max Plus. Always match the adapter to the exact housing version you own.
