*CRI is a measure of a light source’s ability to show object colors “realistically” or “naturally” compared to daylight, which has a CRI of 100 and represents the maximum value.

The beam angles for the Sea Dragon lights are shown as the true, tested “in-air” (above water) beam angle. Underwater, due to light refraction, the angle tightens to approximately 33% less.

Avoid using this Sea Dragon light above water for prolonged periods of time
The light is designed for underwater use and water is needed to displace heat. The metal light head at full power will reach temperature of about 140F (60C) degrees within a few minutes, which may cause burning if touched. A thermal sensor will automatically dim the light if internal temperatures reaches 150F (65C) degrees. Immediately turn off light if any parts of the light become hot to the touch.

Q: When will SportDiver ANDROID version be available?

A: App engineers are working on the Android app, which will be compatible with the same SportDiver underwater housing (item # SL400) that is currently used for the iPhone. The SportDiver Android app will be available in June 2021.

Q:  Can I lock and unlock the phone when it is inside the SportDiver housing to save battery power?

A:  It is not possible to lock or unlock the phone when it is inside the housing.  Apple iOS controls that function.  The phone must be unlocked and SportDiver app running when it is inside the housing. The app has a power save feature which dims the screen by 80% and turns off the camera.  Push any button to “wake-up” the phone. Also turn off any apps running in the background to further save battery power. With these power save features, the phone’s battery should last at least 2 dives, so there is no need to open the housing between dives.

Q:  Can I take a picture while recording video?

A:  Not currently, but the SportDiver app does have a “Photo + 3 sec. Video” setting, which records 1.5 seconds of video before and after the picture.  We are continuously working on improving the app features and hope to add PIV (Picture-in-Video) feature with future app update.

Q:  Will the SportDiver Bluetooth interfere with my dive computer or other Bluetooth devices?

A:  There should be no interference issues with the SportDiver and any other Bluetooth devices.  The SportDiver has been tested and certified by testing lab for FCC and Bluetooth compliance, which specifically tests for interference among other radio frequency compliance regulations.  In addition, the SportDiver uses frequency-hopping Bluetooth Low Energy wireless technology which does not transmit through water (i.e. to your dive computer)

Q:  How do I get my iPhone 12 / 11 Pro Max to fit in the housing?

A:   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.

Q:  I can’t play the .MOV videos on my Windows computer

A:   Use VLC Media Player, which is a free download at

Q:  When I put my phone into the housing, Siri appears because the volume button was pressed accidentally.

A:  You can move the rubber grip tabs around so they do not touch the iPhone buttons. Page 14 in manual.

Q:  When I put the phone into the housing the leak alarm goes off.  

A:  Your finger is conductive like water, so touching the water sensor will activate the alarm. See Page 21 in manual.

Q:  Is there a way to use the SportDiver without the vacuum pressure leak alarm  or is it mandatory?

A:  Yes, you can disable the pre-dive vacuum pressure leak alarm in the bottom of the Settings Menu.  The water sensor leak alarm cannot be disabled.  See Page 37 in manual.

Q:  I pumped too much and got “over-pump” warning but couldn’t release the pressure with my finger or a pen. Am I doing something wrong?

A:  Move the rubber tip sideways – don’t push down on it.  See Page 24 in manual.

Q:  Sometimes the button response is a bit slow in the Settings menu.

A:  The lens setting has a 1 second delay when changing lenses, which is necessary for stable app performance.  See Page 35 in the manual.

Q:  When I want to save a RAW, what is the difference between the JPG and the RAW in the iPhone?  Normally my phone doesn’t have this feature. 

A:  The JPEG is the processed image using iPhone’s image processing technology.  The RAW file is the native unprocessed image from the iPhone sensor.  The SportDiver doesn’t do any processing of the RAW file.

Q:  Are you planning to make an adapter for the front to be able to use a wide-angle or macro lens with the housing as well?

A:   Not at this time for several reasons:

  1. Most iPhone have multiple lenses including telephoto and wide angle, which are better than shooting through an additional wet lens.
  2. A wet lens needs to be perfectly centered over the iPhone lens or there will be distortion. That is very difficult to do accurately.  Also, the lens would need to be manually centered every time the phone is installed because the phone will be in slightly different position.
  3. Using a wet lens for one iPhone lens will block-out the other iPhone lenses.

Q:  Can you use the flash of the iPhone so that you can connect an external strobe?

A:   No.  The iPhone’s LED Flash is next to the lens and will cause internal glare.  Therefore, the strobe light has been permanently disabled.  Another issue is that the iPhone uses a pre-flash to control exposure.  That requires a special strobe to mimic the pre-flash and then deploy a primary flash, which strobes typically won’t do.  A photo-video light is the best lighting accessory and easy to use.

Q:  I can’t see the menu items for some reason. Only the select menu setting is visible.

A:  Change the iPhone’s Display & Brightness setting from “Dark” mode to “Light” mode.  A future app update will allow you to read the full menu in Dark mode.

Q:  Do I need cellular service to be able to use the SportDiver with my iPhone?

A:  No, you just need WiFi to download and install the SportDiver app from the App Store to the iPhone, and a current version of iOS.  Cellular service is not needed. 

Q:  What is maximum operating altitude for the SportDiver housing?

A:   The SportDiver housing vacuum pressure check (leak analysis) works up to altitude of 6000 ft / 1829m (11.8 psia). At higher altitude, the SportDiver LED status indicator will show red/green/yellow error code.
