I was in Lunarfins Scuba Club meeting in League City, Texas, few days ago listening to members sharing their recent dive trip experience. One member mentioned about what happened during diving Blue Hole in Belize. The plan was to descend to 130 feet to see stalactites (that were formed during previous ice age, when the sea level was probably 150-200 feet below the present sea level), hung around there for 2-3 minutes and ascended up when the NDL went to zero (I’ve done it before, as shown in the video, below). The whole dive may be lasted for 15-20 minutes (sort of a bounce dive). One of the divers did not stop at 130 feet depth. He kept going to 150 feet on AL80. When DM noticed it, he reached out and pulled the diver up. Later on when they were back on the boat, the diver started to not feeling well, showing some signs of DCS. The crew sent him to decompression chamber.
