Since I’ll be in Tioman this weekend, I would prefer to do a speciality dive…perhaps the Multilevel Diver speciality…rather than diving without purpose. I know I’ll be doing some underwater photography as usual, just to keep myself occupied, but it is time to move on. I must further my qualifications.
I’ve been spending almost every free time of my free nights revising my wheel Recreational Dive Planner, and have been reading more about nitrogen narcosis (from where this site got its name) to plan for my normal air dive to 57 meters, which really is, the depth limit for any normal air dive. Anything deeper than 30 meters is not really safe, and divers are more exposed to nitrogen narcosis at this depth. Recreational diving sets its limit at 40 meters (which is the depth US Navy sets for normal air dives), and 42 meters in case of emergency. Any deeper would be dangerous, anything deeper than 57 meters is..crazy.
Since I have been doing lots of multilevel diving, I guess I may as well make it one of the speciality ratings I’ll be going for.
