I am not going to debate arbitrary deep limit 30m for non decompression dive, but non arbitrary limit is 40m if you dive deeper than 40 m that it's your own risk.
Also what kind of insurance you take, even using DAN there are option for 30m,40m, and 50m (or 60 m can't remember). Important to know insurance cover limit and those fine print.
I am quite a new diver but I know the most important thing to have is reliable dive comp first, anything happen the log from dive comp is the best evidence to support claim.
Anyway beyond 30m usually is not much interest plus short bottom time, except there something specifically interesting thing there.
