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 (Water Detected) keeps activating

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.

A common cause for this issue is water drops entering the housing when opening the housing after your dive. The water drops may not be easy to see and may travel down behind the gold-plated wet sensor.

After use, dry the housing with a towel. Before opening the waterproof door, make sure you and the housing are dry. Open the door with back of housing facing down (lens facing up) to prevent water drops from entering the housing and activating the leak alarm. Use a lint-free cloth to blot-dry the O-ring. Once O-ring area is dry, remove the phone.

3. Housing frequently fails the 3.5-minute Leak Analysis

The purpose of the Leak Analysis is to check if the housing maintains an airtight seal before diving. After sealing the housing and applying the vacuum pump pressure, the housing monitors the internal air pressure for any changes. If the housing loses internal vacuum pressure, the phone will display “Leak Detected” or “Keep Pumping”, depending on the amount of pressure change. If the housing maintains vacuum pressure, the leak analysis will be successfully completed, and the housing is ready for diving.

Here are the most common causes for a loss of vacuum pressure resulting in leak analysis failure:

  1. The O-ring is not lubed, dirty or damaged. Clean O-ring and apply very thin film of lube. Replace the O-ring if cut or damaged in any way. One free O-ring is included with each SportDiver. A spare O-ring set may be purchased at your local authorized SeaLife dealer. See item #SL40010.
  2. The O-ring is installed incorrectly. The O-ring is “D”- shaped. The flat side of the O-ring must be against the O-ring groove with the round side facing outward. Make sure the O-ring is not twisted.
  3. The yellow one-way rubber valve at the vacuum check port is damaged or has some dirt/debris trapped underneath. Clean the one-way valve using lint-free cloth moistened with alcohol. Use pressured air to blow out any dirt/debris trapped underneath the one-way valve. If the one-way valve is damaged, 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
  4. The vacuum check port O-ring is not lubed, dirty or damaged. Clean O-ring and apply very thin film of lube. Replace the O-ring if cut or damaged in any way. One free O-ring is included with each SportDiver. A spare O-ring set may be purchased at your local authorized SeaLife dealer. See item # SL40010. Note: Screw on waterproof cap after applying vacuum pressure and always make sure waterproof cap is installed when diving.
  5. Changing air temperature inside the housing during the leak analysis will cause the vacuum pressure to change and may activate the alarm or “keep pumping” message. For example, if the housing is taken from a cool air-conditioned room to the warm outdoors. If the housing is warming up during the leak analysis, the housing’s internal air expands causing vacuum pressure to drop and the leak analysis to fail. Make sure to allow a cool housing to adjust to the warmer ambient temperature before starting the leak analysis.
    Inserting a hot phone into the housing before starting the leak analysis will also cause thermal expansion inside the sealed housing and vacuum pressure drop. A freshly charged phone may be hot. Also, unused apps running in the background will draw battery power and generate heat. Force off all apps running in the background, except for the SportDiver app. Also, allow a hot phone to cool down before starting the leak analysis.

4. The 3.5-minute Leak Analysis not working at high altitude

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.

5. How to fit larger phones, like iPhone 12 Pro Max, into the SportDiver housing

Replace the pre-installed medium-sized rubber grip tabs with the small-sized grip tabs.  For some of the largest phone models, you may need to remove the grip tabs on the left side and use small grip tabs along the bottom. The online compatibility chart shows “0/S” in the grip tab size column, which means no grip tabs on left and small grip tabs on the bottom.  The other grip tab sizes are in the white envelope included with the SportDiver. Please refer to the instruction manual for more details.

6. 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.

7. 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.

8. 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.

9. 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. To eliminate the gap [and glare], select the appropriate rubber grip tabs along the bottom and side. For example, the iPhone 11 Pro fits well inside the SportDiver housing using medium size grip tabs, but that creates a gap above the phone. Using large grip tabs along the bottom and small grip tabs along the left side eliminates the gap. See iPhone 11 Pro before and after pictures below.

10. 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.

11. Cannot release vacuum pressure with my finger or a pen

Move the rubber tip sideways to release internal vacuum pressure.  Pushing the yellow 1-way valve down will not release pressure.

Back to Index


12. Rear buttons are not working

The rear housing buttons will only work with the SportDiver housing is sealed and vacuum pressure is applied.  The rear button is a mechanical and pushes the corresponding button on the inside the housing.  If the housing is sealed without vacuum pressure, the rear buttons may not make contact with the internal button.  Applying vacuum pressure will ensure the buttons make proper contact.

14. Screen not always dimming when iPhone is in Power Save (iPhone only)

We have recently discovered that some iPhone models may automatically undim the display even though the phone is in Power Save mode.  The phone will normally go into Power Save mode if no buttons are pushed within 1 minute. The display will dim and camera turns off [showing a frozen image] to conserve battery power. Pushing any button brightens the display and “wakes-up” the camera.  Some iPhone models may automatically undim the display when moving the phone without touching any buttons.  The camera does remain off until a button is pushed.  Changing the phones Display settings or SportDiver app Power Save settings does not fix the issue. App programmers are investigating the cause and solution for this issue and will release app update ASAP.

15. App crashes when deleting last remaining photo (iPhone only)

Using the SportDiver app to delete the last remaining photo or video will cause the app to crash. There must be at least one photo or video in Playback. When installing the app, one photo of the app start-up screen is automatically saved in Playback. Please do not delete the last remaining photo or video.

Note: Deleting or moving the SeaLife SportDiver folder in the iPhone’s Photos app, will not cause any issues. A new SeaLife SportDiver folder with one photo will automatically be created the next time you open the SportDiver app.

16. Zoom function not working in Photo mode with iPhone SE or Xr, but works in video mode

We are aware of this issue and continue working on solution to allow zoom function with iPhone SE (2nd generation) and iPhone Xr. This is not an app bug – There is an iOS systems limitation within the iPhone SE and Xr that blocks out the zoom function. An app update will be released if and when a solution is found.

17. “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

18. iPhone “Back Tap” feature activates while underwater

Back tap is an iPhone feature that performs select tasks when tapping on 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.

21. 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.
