SportDiver Underwater Housing

(See below for App troubleshooting)

1. Important Product Information

Make sure you and the SportDiver housing are completely dry when releasing the vacuum pressure and opening the waterproof door. Releasing the pressure with a wet finger will result in water drops getting forcefully pulled into the housing and internal electronics. Not following these important instructions may cause the leak alarm to activate and damage the electronics.

2. Leak Alarm activates as soon as housing is powered on

The gold-plated wet sensor is located on the inside bottom right of the SportDiver housing. The leak alarm will activate if anything conductive touches the wet sensor – your finger, water drop(s), dirt/debris, etc. If the alarm activates every time you power on the housing, some water drops may have entered the internal electronics behind the wet sensor, or the sensor has become damaged. Try these troubleshooting tips:

Power off the housing. Use a cotton cloth to clean and dry the wet sensor. If leak alarm still activates when powering on the housing, use a thin strip of tissue paper to absorb water droplets trapped behind the wet sensor, particularly on the back right of the wet sensor near the lead cable.

If the leak alarm still activates every time you power on the housing, some water drops may have deposited on the internal electronics. See above Important Product Alert. In this case, insert a new Moisture Muncher desiccant capsule inside the housing and keep the rear housing door sealed for one or two days. For faster drying, use a hair dryer on low heat / low fan speed. Direct the warm air towards the wet sensor for about 5 minutes. Be careful not to overheat the housing.

If the above information does not fix the issue, please contact the SeaLife Service Center in your country. For a list of dealers/distributors that can offer repair service, please visit the SeaLife website at

3. How to fit iPhone 12 / 11 Pro Max into the SportDiver housing

Replace the pre-installed medium-sized rubber grip tabs with the small-sized grip tabs.  The small grip tabs are in the white envelope included with the SportDiver. See page 14 of the manual for details.

4. Cannot open the housing

The internal vacuum pressure must be released before the housing can be opened.  Unscrew the vacuum check valve cap.  Use your fingertip to move the rubber yellow 1-way valve sideways to release the pressure.  Do not push down the valve as that will not release the pressure.  You may also use some unsharp object, like a pen cap, to move the valve sideways.  Never use sharp object near the rubber 1-way valve.

5. Attaching wrist strap to the underwater housing

The housing wrist strap included with the SportDiver UW camera attaches to the housing as shown below. Attached the looped end of nylon cord through the housing strap connector (A). The clip (B) is used for attaching the camera to your BCD (buoyancy Control Device) D-ring. Adjust the sliding lock (C) to tighten around your wrist.

6. Fogging inside the housing lens

Humid air or water drops trapped inside the underwater housing may condense on the cooler glass lens port and cause fogging. Here is the best way to prevent fogging:

  1. Do not allow any water drops to enter the inside of the housing. Even one water drop can evaporate and condense (fog) on the lens port.
  2. The phone must be completely dry before inserting it into the UW housing.
  3. Load the phone and housing in a dry environment, like an air-conditioned room. This will help to avoid trapping humid air inside.
  4. Avoid letting the housing get hot or sit in direct sunlight for pro-longed periods of time.
  5. Avoid opening the housing in a humid environment. If you need to charge the phone between dives, make sure you and the phone are dry before opening the housing.
  6. Use a fresh Moisture Muncher desiccant capsule (item # SL911) inside the housing.

7. Glare showing up in photo

Glare in the upper left corner may occur when a bright light or sunlight is behind you and there is an air gap above the phone. Light is passing through the air gap and reflecting of the inside of the glass lens port. It is more likely to occur on land and not underwater. To prevent this glare, apply a small piece of black tape to the inside of the housing to fill the air gap.

8. Siri launches when putting iPhone into the housing

The volume button is being pressed accidentally. Move the rubber grip tabs around so they do not touch the iPhone buttons. Refer to page 14 of the manual.

Back to Index


9. Leak alarm activates when inserting the phone into the housing

Your finger is conductive like water, so touching the water sensor will activate the alarm. Avoid touching the water sensor. If the alarm goes off by accident, power the housing off and on again. Refer to page 21 of the manual.

10. The 3.5-minute Leak Analysis not working – keeps displaying “Prepare Housing….” message

After preparing the housing and applying vacuum pressure, the app keeps displaying Please Prepare Housing message and status LED continuously flashes red, yellow and green. This issue is most likely caused by exceeding the SportDiver’s high altitude pressure limit. The SportDiver housing vacuum pressure check (leak analysis) works up to altitude of 6500 ft / 1980m (11.6 psia). At higher altitude, the SportDiver Leak Analysis will malfunction and LED status indicator will show red/green/yellow error code.

13. “Keep pumping” or “Leak Detected” message appears during 3.5-minute leak analysis

The most likely cause for “Keep Pumping” message is heat build-up inside the sealed housing. After reaching the “Good” vacuum pressure and 3.5-minute leak analysis starts, and heat build-up will increase air pressure, reducing vacuum pressure. To prevent heat build-up, allow the housing to adjust to the ambient temperature before starting the leak analysis. In other words, taking a cool housing [from air-conditioned room] to a warm tropical climate will cause heat expansion inside the sealed housing, which can be avoided by allowing the housing temperature to adjust to near ambient temperature. Also avoid exposing the housing to direct sunlight.

If the “Keep Pumping” message still appears, try giving an extra ½ to 1/3 pump after reach the “GOOD” target vacuum pressure. The pressure gauge should remain in the “GOOD” range. This little extra vacuum pressure should help to offset any heat expansion, particularly in hot tropical climates. 

If the above information does not fix the issue, please contact the SeaLife Service Center in your country. For a list of dealers/distributors that can offer repair service, please visit the SeaLife website at

14. iPhone “Back Tap” feature activates while underwater

Back tap is a new feature with iOS 14 that performs select tasks when tapping the back of the phone 2 or 3 times. Back Tap should be turned Off when the phone is inside the housing because it may accidently perform the task and close the SportDiver app if the housing gets bumped or knocked.

18. Vacuum pressure check (Leak analysis) not working at high altitude

The SportDiver housing vacuum pressure check (leak analysis) works up to altitude of 6500 ft / 1980m (11.6 psia). At higher altitude, the SportDiver LED status indicator will show red/green/yellow error code. 

When diving at altitudes higher than 6500 ft, you will need to disable the leak alarm in the SportDiver app Settings Menu. Make sure you carefully set up the housing to avoid a leak – inspect, clean and lube O-rings, and properly seal the waterproof door. You also need to add two pumps of vacuum pressure after sealing the housing even though the leak alarm is disabled. The vacuum pressure helps the waterproof door to fully seat itself into the housing, creating a strong seal.
