Once your phone is sealed inside and the leak check is complete,becomes a dedicated dive camera
SeaLife Ultra Smartphone Housing – Excellent Underwater Option I recently bought the SeaLife Ultra smartphone underwater housing. I had been considering the GoPro Hero 13, but chose this instead because my iPhone 17 offers better low‑light performance. After using it on a dive trip to Oahu, I’m very happy with the decision. The housing feels solid and well‑built, and the companion app works smoothly. It’s a little unnerving putting a brand‑new iPhone underwater, but the system performed flawlessly. It fits my iPhone 17 and my wife’s 17 Pro (her case had to come off to fit). Pros • Very easy to use once set up • Your underwater camera improves every time you upgrade your phone • All photos and videos are already on your phone for quick editing and sharing Cons • There’s a bit of a setup procedure before each dive • It’s smart to run a leak check on shore • The leak test takes about 3 minutes • Once sealed, the phone can’t make calls or send messages until removed • Between multiple dives, you’ll need to remove and reinsert the phone if you want to use it Overall None of the drawbacks were dealbreakers for me. The housing worked great, delivered excellent image quality, and gave me confidence underwater. A strong choice for anyone who prefers using their smartphone as their dive camera.

Just love this case. Easy to use and high quality case.
This has been the best under water camera case I have ever purchased. Worked perfectly with our Samsung S24 Ultra phone; which is the larger sized phones. Not once did we have any experiences and the included red filter made the pictures from under the water amazing in color. Even one of our tour guides on the boat, raved about his SportDiver case. It was great to hear as it was our first use of the case before our snorkel at Molokini Crater Snorkeling Tour. I would recommend though to purchase extra box of "Moisture Muncher Capsules" which pulls any existing moisture in the case from the phone and case. We had a 50% blue change of the beads after 6 uses in a week. Another consumable I would suggest is to get would be to have an extra "tube of SeaLife Silicone Lube for SportDiver O-rings".

Great SCUBA Camera
Great camera case. I was looking for an inexpensive underwater camera for SCUBA diving. This was perfect. I used an old cell phone for the first dive. The Bluetooth controls that let the case control the phone's camera are great. So simple to use. I do suggest you buy a light for better colors, and make sure you buy some Moisture Munchers before the trip (the case only comes with one).

Does NOT disappoint
I am SO happy I bought this for my Samsung Galaxy S21 Ultra 5G phone. It has upped my photography game a lot. It allows me to zoom in and out, switch from camera to video, change some settings and view the photos and videos I took. I have had zero issues with any moisture getting into the housing but, I also have followed their instructions in how to use it. There are only two things that I don't like but I'm not sure that they can be fixed. 1. Switching from the four options on the left side (camera, video, settings, review) is difficult to see which one you are on while you are under water. Instead of that specific item lighting up as white (since the rest are then only slightly gray), perhaps they can all be red or blue for the ones you are not using and white for the mode you are in? If not, maybe the one you are in is significantly brighter white while the others are very dull. 2. When using the video and I zoom in and out, there is a loud clicking noise for each time I press the zoom in/out buttons. That sound ends up on my video. I found that to be very annoying. I don't know if this is fixable or not since the mechanism of the housing might not be something that can be improved to make the buttons silent. Otherwise, I'm glad I bought this and can't wait to take more pics now that I live on a Caribbean island with dozens of beautiful snorkeling spots. Here are a couple pics I took the other day. Mind you, I did some minor post editing so I'll include the photo as it was taken and then the post edit one also.

Fantastic iPhone Underwater Camera Housing!
Easy to use with clear instructions for amazing underwater photos and videos! Just download the Sealife app onto your iPhone, power up the housing, and let the instructions and the app guide you through the process to prepare the housing and conduct a leak test before submerging the unit in water. The red filter works perfectly to color-correct at depth, and it’s easily removable for shots above the surface. A must-have for the underwater photography enthusiast!

Great photos, but not worth the pain
The idea behind this product is great! Unfortunately, this is the 2nd time I have purchased it and this time was worse than before. The first time having the product was in 2024 and I used it often during the 6 weeks I was earning my divemaster in Indonesia. At times it would be fussy and not pressurize correctly (or claim that it wasn't pressurized). Eventually, I was able to take pictures underwater without it going through it's pressurization test. In general it added a lot of stress to getting everything set up. And one afternoon, I was rushing to get my gear on, and trying to deal with my phone and case and my phone screen cracked. (it's not fun being in a remote island without a phone). So I went a year and change going back to my old Go Pro dupe. It's basic it was fine, but then I wanted to try this again on my next scuba dive. I didn't realize I purchased a used device (or at least the moisture muncher was missing). I now have a Google Pixel 8 Pro, and it was not fitting into the device nicely. I've learned from my prior mistake to never try to rush the process. Unfortunately, I was never able to bring it in the water because it could not pressurize appropriately. Plus, it cracked my screen protector on my phone. Now having had this device twice, when it works the picture quality is great (as long as you have a good camera on your phone) BUT it is certainly not with the hassle, the embarrassment of having that annoying beeping sound happen over and over again, nor having a broken phone or screen protector. Phones are meant for land! Sadly I missed my 30 day return window and now I have a very expensive piece of plastic that I can't do anything other than get anxiety from the beeping when the pressurization doesn't work.

Underwater
Wonderful product it was able to work with my wife's phone took perfect pictures all the way down to around 80 ft we did not go deeper than this. Although it is very expensive it is possibly worth it if you want some really nice pics which actually depends on your phone's camera capability as well.

Substantial, well made
Really good quality case, everything needed to take underwater photos whilst diving. I’m using it with my old iPhone 13 as my new 17 pro gets its lidar blanked off and Ben though it fits perfectly. App is super easy to load and operate. Looking forward to trying it out for real. Comes with an everything you need to get started including spare seals and grease. I’ve ordered extra desiccant packs as you only get one, but the AAA batteries were included

Conforme à mes attentes
Je l’ai utilisé 1 fois, facile d’utilisation, rassurant avec le test d’étanchéité. Ok pour les manipulations avec gants étanches. Je n’ai pas rencontré de problèmes particuliers. A conseiller.
