Rules of Third


Bobby CAU

Recommended Posts

The rule of thirds is for scuba diving, one third of your air is used on your progress away from the dive boat, one third is used to get back to the ascent line to the boat and the last third is used for safety stop at 15 ft to release nitrogen gas from your tissues and any emergency you might encounter. That emergency is usually "where the hell did the line go that takes us back up to the boat".
