It turns your smartphone into an all-in-one dive kit, acting as a dive computer, a fill light, camera and so much more.

  1. Charles Downing

    Perfect for freediving training. I am using this to teach my freediving courses. It is so convenient that i can take the video about my student’s technique and show them right away. It’s easier for them to know which part of the posture that they should improve and this also make freediving teaching so much fun.

  2. Jerry Taylor

    I actually got to use HotDive through my friend’s first. I was very satisfied with all the features that they offer and the fact that I can keep using the housing even when I change my phone. 4K and RAW is available! Definitely recommend!

  3. Elaine

    My iPhone 12 pro max fits perfectly! The housing was sturdy and safe even at 100ft deep. Next time I will try to use underwater 200ft deep! I went on a dive with this pro a couple weeks ago and took great pictures. I would definitely recommend this to anyone as one of their uw camera.

  4. John Edginton

    First time using HotDive. I learned a few things. Very happy with the results. IPhone 11

  5. Marko T.

    Easy to use, can take professional pictures, and there’s a diving computer function as well! I don’t have to carry bulky underwater cameras or a diving computer, etc. Very convenient, and I’m totally in love with this gear.

  6. Tony Leung

    best case ever!

  7. Will S.

    Only my Samsung S21 ultra is not able to use, the lens window is too small, so I use my spare phone S21, well, perfect then.

  8. Jasmine T.

    I really like the amazing pictures I got using this housing with my iPhone 12 Pro. It’s very easy to set up and syncs easily using Bluetooth technology. The vacuum pumping takes less than 1 minute to complete, and it is automatic! I would definitely recommend this to my dive buddies.

  9. Marc Majka

    I have a GoPro and a Diveroid. This is by far easier than either and takes good photos and video at deep to 260ft. I have used it 3 times and my Samsung S9 fits very well.

  10. Jules Gallagher


    Did 3, 2-tank dives without an issue. It can be a little daunting remembering all of the steps to set up your phone and the case, but after the 1st time, the case is a breeze… I’ll probably make a cheat sheet to remember the phone settings. No issue with bluetooth synching. iPhone12.

  11. Jose B.

    I first bought HotDive H1 via Kickstarter a year ago and was amazed by the quality and fuction of the product. I have dived with HotDive as deep as 220ft and didn’t have any problems! THis one is for my sister, she loves to take underwater pictures and share on her Instagram, so I think this would be a very good gift for her! i believe she will love it!

  13. Caro M.

    spectacular product, it looked brand new despite the outer box being a little weary and it had some strange tears along with it. I’m glad that the actual casing was perfect though! it wasn’t hard to figure out for me as it is my first one. happy that it’s compatible with my samsung note smartphone.

  14. Jessie J

    It comes with an app or software that you can install I your phone and will provide you a wide range of options. Like changing ISO, white balance and more. To me that I am just getting used to this world of photography some things took me a while to understand and learn. I had to play with it for a little bit until I felt comfortable. But once you get to the point that you know how to make it work, it becomes really easy.
