Approaching this too casually?

the main problem with the iphone route is not the photography, which it does decently well. It's that if you do flood it, the inconvenience factor is much larger. Even on vacation, most rely on their phone for some amount of communication or information, even if just relying on wifi hot spots. They're also now running considerably more expensive than say the TG-6, which is on holiday sales right now for 350.

A housing that says it's good to 4m is essentially worthless for ocean use. It isn't even guaranteed to be safe in a swimming pool. Understand that when it (or watches) give their depth rating, it's for static pressure. When you dive down (or drop it), the housing experiences dynamic pressure which is why watches with 50m ratings really don't fare well for divers, even though it's beyond the recreational limit for divers. Also, this depth rating presumes clean seals - a single hair or grains of sand can compromise it. For those using it once every couple years, much higher chance of screwing it up. (sadly, that's true for the tough cameras as well)

So you need to spend a bit more than whatever that runs. I suspect > 100. And at that point, the TG starts looking better again. Now if you have an older iphone you no longer use, that would be a fine candidate.

Can also consider the recent generations of gopros.

I’ve decided to get the latest GoPro. Never had one before, but kind of excited to try it out. The price is about the same as the TG, same sensor as well, but more versatile. I can imagine using it for other purposes on land, whereas the TG I cannot.
