Is the PADI Recreational Dive Planner Still Relevant in the Digital Age?

{INTRO}

Having taught numerous PADI Open Water Scuba Diver courses and spent hours studying how to utilize and effectively teach the PADI Recreational Dive Planner (RDP) – I’ll be the first to say it is time consuming and often intimidating for novice divers.

In the age of hi-tech dive computers and mobile applications, do you really think teaching divers to use the PADI Recreational Dive Planner (RDP) is worth the time?

Compared to modern dive computers, are they outdated?

My answer may surprise you! Let’s DIVE into the RDP’s role in safe diving.

Both dive computers and dive tables are vital tools designed to assist divers in planning their dives effectively. They both provide essential information on no-decompression limits, surface intervals, and maximum depth for safe diving. However, computers are much easier to use and teaching tables effectively, especially to new divers, is time consuming.

Utilizing Dive Computers: The Pros and Cons

Dive computers are so powerful in planning dives safely that they are mandatory on many boat charters. Despite being costly, their accuracy, ease of use and amount of real-time information that they display make it a “no brainer.” Every diver should own and utilize a dive computer to maximize safe diving. Period!

DIVE COMPUTER PROS

• Ease of use – Most modern dive computers are designed for ease of use with user-friendly interfaces and simple button controls.
• Longer bottom times – Dive computers accurately calculate a diver’s depth profile and in real-time, which extends bottom time.
• Accuracy – Real-time tracking and advanced algorithms allow dive computers to provide precise information.
• Real-time information – Facilitates informed decisions by providing constant monitoring of depth, time, remaining bottom time and ascent rates during dives.
• Ascent rate monitoring – Alerts the diver if they are ascending to quickly
• Alarms – Many models provide both visual and audible indicators
• Logging – Allows divers to track their experience, trends, improve skills and remember details about past dives.
• Air integration – Makes diving safer through convenience.

DIVE COMPUTER CONS

• Cost – Can be expensive, especially for new divers.
• Learning Curve – Can be a learning curve, even though they are generally easy to use.
• Malfunction – Dive computers can malfunction during a dive and could prevent further diving unless you have a backup.

Utilizing Dive Tables: The Pros and Cons

Dive tables are often considered somewhat outdated due to the prevalence of dive computers. They also come with a steep learning curve and are often much more time consuming to teach than their counter part, the dive computer. Are dive tables still relevant?

DIVE TABLE PROS

• Conceptual Understanding – Teaching/learning dive tables alongside the dive computer helps divers grasp the principles of dive theory.
• Backup System – Dive computers can malfunction, in which case divers can rely on dive tables to plan dives.
• Accessibility – Dive tables are affordable, readily available and don’t rely on batteries or charging, which makes them reliable in any situation.
• Capability – With the right knowledge, divers are capable of using tables to plan complex dives and are often used in technical diving to calculate gas mixtures.

DIVE TABLE CONS

• Accuracy – Compared to modern dive computers, tables are less precise in calculating decompression needs.
• Human Variations – Tables use a standardized model that don’t account for levels of individual fitness or body composition .
• Real-Time Use – Consulting a table during a dive can be challenging and time-consuming.
• Potential for Error – Misinterpreting the table or making calculation errors during a dive can increase the risk of decompression sickness

Teach/Learn the Recreational Dive Planner?

Absolutely yes! To my knowledge, every diving certification agency (PADI, SDI, SSI, NAUI, etc.) mandates that instructors teach, though minimally, the recreational dive tables as part of their curriculum, even if most modern divers primarily rely on dive computers for their ease of use and accuracy. But why?

It’s simple! As powerful as modern dive computers are, they nearly become invincible when accompanied by dive tables. Dive tables reinforce gaps in the power of dive computers by helping us understand dive theory and how computers calculate decompression data. They also serve as a reliable, inexpensive backup in case the dive computer malfunctions.

Conclusion

All divers should own and utilize dive computers. They should also own and understand how to use recreational dive planners. Despite being outdated in comparison to the modern dive computer, RDPs continue to hold its relevance in today’s techie underwater world.

If you’re an instructor, teach dive tables in conjunction with the dive computer.

If you’re a diver, utilize a dive computer for diving, but learn to use dive tables.
