One of the hardest areas for divers and dive professionals to learn is calculating dive tables. Yet, it's vitally important to be able to properly plan your dives, or you risk getting decompression sickness - also known as "the bends" - a debilitating and even fatal consequence of improper dive planning.


Many divers think that dive computers have replaced dive tables. Although dive computers are incredibly popular for dive planning, they are still a piece of technology that can fail. If your dive computer fails due to a low battery you still must be able to properly plan your dives. Plus many divers rent equipment or can't afford dive computers right away. So, the dive tables will be with us for a long time!


When you become a PADI Divemaster or a PADI Open Water Scuba Instructor you MUST know how to work dive tables. For divemasters, you will be helping divers plan their dives - often using dive tables when their computers aren't available. And for instructors, you will need to know how to teach dive tables to your students. Because of these duties and responsibilities of dive professionals, PADI will test you on dive tables!


No one, at any level of scuba diving instruction, wants to fail their exams. And dive table are an area that both divers and pro's often fail on their exams. It is not only embarrassing, but at the pro level it can be time consuming and costly.


The How To Use PADI Dive Tables course is designed for every level of diver to let you:

  • Properly plan all type of dives
  • Avoid hours of supplemental lectures, reading and calculations
  • Pass your quizzes and exams with flying colors
  • Avoid the embarrassment, expense and time of failing your exams
