Lol, boomer scuba diver has outdated info from the 70's...
" The most common depths for experienced scuba divers is between 20 to 30 metres (66-98 feet). With experience and the right scuba diving certification, recreational scuba divers can go to 40 metres (131 feet) deep with PADI and 50 metres (164 feet) deep with BSAC"
Trained divers can go FAR past those depths with the right tanks and staging... 300 feet is nothing, and cave divers go that deep all the time on rebreathers...
