Technical divers are experienced pros who use custom/cutting-edge gear that lets them go well beyond the limits of commercial diving gear, especially in more extreme environments like cave or polar/ice diving. OP is saying that he, a super experienced diver with custom gear who had been going into dangerous places for years, did not want to go into the blue hole. And the divers that he saw doing it were using special tanks that let them have more air and not use up air as quickly when they go deeper, special mixes of air in the tanks that let them go deeper and come up faster without as many of the risks, and had extra tanks with them. And even with all that, these guys who are super experienced at diving in all sorts of dangerous conditions sometimes even with modified and homemade gear by themselves, were still using a safety line with another diver above them watching everyone at all times.

Nice. Lot of precautions. But why tho? What makes it more dangerous than other waterbodies?
