What is the 120 rule in diving?
Subtract the depth you’re diving (in feet) from 120. The resulting number is the maximum amount of minutes you should spend at that depth. Here’s how it works: Your max depth (in feet) + your bottom time (in minutes) should be less than or equal to 120. That’s it. So if you plan to dive to 60 feet, the rule says you shouldn’t stay down longer than 60 minutes.

What is the scuba 1/3 rule?
The Rule of Thirds is a guideline used by scuba divers to manage their air supply effectively throughout a dive. It involves mentally dividing one’s breathing gas supply into three equal parts. One-third for the outward journey, one-third for the return journey, and one-third as a reserve or emergency supply. In technical diving, the 1/3 Rule ensures divers have enough gas for the descent, return, and emergencies. It divides the total gas supply into three parts: one-third for the descent and exploration, one-third for the return, and one-third as a reserve, enhancing safety in challenging environments.
