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.

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.

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.For divers following the rule, one third of the gas supply is planned for the outward journey, one third is for the return journey and one third is a safety reserve.
Why is scuba diving expensive?
Scuba diving equipment Besides the learn to dive accreditation classes, the other costs involved to get into scuba diving will be buying the necessary scuba diving gear. Just like golf clubs, scuba diving gear comes in top of the range and budget friendly options. It largely depends on how often you get to dive. Buying a basic scuba gear set would cost around $300, and a complete scuba gear set would go up to $1000 or more. Renting a scuba gear unit would cost you less, at just $30, and it would be a better solution if you plan to dive only once a year or during a vacation.A scuba course can run anywhere from $399 through $1,000 depending on the dive shop/operator, the dive agency and the dive instructor. If you need to dive in very cold waters you might also need to add on a drysuit specialty, or a drysuit checkout. That should cost you less than the open water course.
