For scuba diving you will want to have a house for the camera regardless of brand. It not only lower the risk of damages, but it is also more explicitly designed for depth without needing to compromising for non-divers.

That said, GoPro is not the best for low light environments, and the battery is a bit temperature sensitive, both which can be an issue when diving.

GoPros (at least the early generations) required a special housing for use in water. My first GoPro was a 2 I believe and I bought it for scuba and it was terrible. Then the newer models came out promising better performance for diving, so I upgraded... and it was terrible as well. Gave up on GoPros after being sucked in twice and not getting the results I was hoping for. It was ok for other things, but anything involving water was not great.

I believe things eventually got sorted out for water use, but I was no longer a customer.

Hahahah. Do you seriously just take random objects deep underwater and expect them to be designed to withstand that sort of an environment?

Was the GoPro you bought rated up to that depth or something? After a cursory look online, they're only rated down to 10m, which is about what I'd expect.
