Well the wife just surprised me with an early birthday present offer (I suspect my shared YouTube history researching cameras and Sardinia appeared on the TV) - to get the DJI Osmo Action 6 with the snorkelling kit (camera is 20m resist but the kit has a 60m external case and the handle floats so if dropped it rises to the surface).
The reason for going with the Action 6 is the underwater auto white balance, good low light and underwater focusing performance, with 4K and 8K. It's conveniently got 50GB internal space on top of SD card (up to 1TB cards) decent battery life and swappable batteries.. etc etc..
Although not as good as the proper cameras for underwater stills and macro etc, I'll not be travelling with lighting etc anyway plus realistically you need a hard external case for them too (the TG6 for example is excellent but there's so many cases of buttons not being secured and leaking. The Sealife 3 looks awesome but it's both limited in capacity (sealed unit) and has limits above water plus feeling like a kids duplo camera with the piano key buttons for scuba gear.
EDIT only down side is the bitrate required for storage.
The manual states 120MB/sec max but that was written before the updates for 4K 30/60/120fps and the 8K 30fps mode was added in the update. True the bus is probably limited to 128MB/sec (let's stick with 2^x to give margin of operating error). Now for the kicker - you expect that to be WRITE speed. So basically none of the cheap MicroSD cards will work.
This mean my Scandisk Endurance 64GB in my existing 1080p won't work. It's a UHS-1 U3 class 10, V30, etc etc.. but 100MB/sec read and 40MB/sec write.. that's not going to give clean 4K... Lexar Professional Silver Plus (DJI recommended) is U3 UHS-1, A2 and V30.. but 205MB/sec read and 150MB/sec write.. £38 for 128GB.. £50 for 256GB.. Simply put certified marking make no sense and it's all down to raw write speed.
Although the native camera is 20m resist, given the number of seals that have to be perfectly closed (all the ports, the lens cover etc), I'd probably not consider using it without the external case. Supposedly the touchscreen works with the case out of emersion but once in the water completely it's disabled. Not a bad idea but at the same time it means you need to surface to change the modes etc.

(it's not a booming party boat) and the crew were awesome! We ended up going to La Maddelena for one trip and to the islands of Tavola and Molara (I keep calling it Molari after Babylon 5) for the other. We also did a 4x4 landcover trip up the local mountain.. you can see some of the local beaches.. and the islands of of Tavola (which cliffs) and Molara (centre image)..
