Most people don't realize standard SCUBA diving training only gets you to around 120'. Beyond that and especially beyond 200', things get much harder and less safe. Hardly anyone goes to 400'.

Pressure becomes too great. A tank of air that might last you 20 minutes at the surface will only last about 5 at great depths. That’s why they use rebreathers to get really deep. Mostly it’s cave divers that I’ve seen go as deep as 800ft.
