Ikelite Underwater Camera Housing for Canon PowerShot ELPH 150 HS, IXUS 155 HS Digital Cameras

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.

This housing is built for the Canon PowerShot ELPH 150 IS, also known as the IXUS 155. Confirm your exact camera model before ordering.

Yes. The housing has dual ports for Ikelite, Sea & Sea, or Olympus-type fiber-optic cables, and it can be paired with an optional AF35 AutoFlash strobe mounted on the grip handle of an optional tray. The strobe fires as a slave triggered by the camera's built-in flash and replicates TTL exposure.

The housing ships with a diffuser, which softens the built-in flash, and a deflector, which redirects that flash toward an external strobe. The AF35 AutoFlash strobe, the mounting tray, external wide-angle or macro lenses, and color-correction filters are all optional accessories sold separately.

Yes. The housing's 3.9 inch diameter flat glass lens port accommodates the Canon ELPH 150 IS / IXUS 155 camera's own lens and also accepts external wide-angle and macro add-on lenses, giving you a wider field of view or closer macro shots depending on which add-on lens you attach.
