I have used a TG-5 for years with excellent results

To get the same quality underwater as you expect from land photo would cost you a ton of cash. Buy the Olympus TG 6 you won't look back

Underwater housings are expensive unless you can find a good deal on a used one. I'd get an action camera or an Olympus Tough. Or a Nikon AW-1 ... these are not made anymore but can still be found as open box or good condition used. I've had good results from mine.

This is the place to start!
Not knowing the level of experience, the desired results, the use or the subject the OP is interested in, this would be an appropriate starting point until the OP has enough experience, knowledge and clarity on outcome to move to something more. Right now the OP has failed to express enough clarity to advise a more costly or targeted approach.

Until you know where you want to go, choosing a route is pointless.

I have the newer TG6 and love it while kayaking without fear of ruining it. I put afloat on the strap in case it drops. BTW it's also shock proof

The TG line is all a novice, uncertain and unfocused underwater shooter like to OP needs. The OP simply has not shown a need for anything more sophisticated. Obviously pros shooting specific subjects will have more involved, demanding and focused needs, but the OP here should just get a baseline underwater point and shoot and be done with it.

Back in the film days I used an ikelite housing with a Nikon F2 and 24 mm lens with 2 vivitar 283 flashes. 14-24 mm should work just fine. Remember underwater clarity most likely will almost always be a bit of an issue especially with flash. Had leakage once while diving in salt water - fortunately no damage. Also at about 100’ depth controls were no longer fully operational due to pressure. Used a Nikonis II for macro with extension tubes and same flashes.

As a long time diver, started with hard hat and then moved into Scuba, I have used some 8 or 10 dSLR housing/camera combinations, Subal and Nikon mostly, in the past few years. But I still dive with my Olympus TG4 with an Olympus housing and an Inon D2000 strobe.
The recommendations made here to start with a GoPro or an Olympus TG 4, 5 or 6 camera with one strobe are wise, as ones tastes and needs evolve rapidly. Housings for DSLR cameras are expensive and time consuming, so best start with a GoPro and/or an Olympus TG-4, -5 or -6 camera.
Also get professional instruction, it pays for itself. Joining an underwater photo trip given by a top teacher such as Mark Strickland of BlueWater Photo is an excellent way to learn, while enjoying a wonderful trip.
