Computers are excellent at telling you your current status, but they are clunky for "what-if" scenarios. A PDF table allows you to visualize and plan an entire weekend of multi-level or repetitive diving in advance.
This table correlates your with your Actual Bottom Time . Find your depth at the top. Follow the column down to your dive time. Padi Rdp Table Metric Pdf
Elias flipped the table over. He found , followed the diagonal line to the 1:30 time slot, and landed on Group E . "That puts us in Group E for the second dive. We’ll have plenty of Residual Nitrogen Time left for the reef at twelve meters later this afternoon."
"Always," Elias replied. He consulted Table 2. He’d been on the surface for exactly 90 minutes. Following the "R" row to the 1:30 interval, he saw his new pressure group was 60-minute compartment Step 2: Calculate Nitrogen Loss During Surface Interval
Dive computers feel like "black boxes"—they give you numbers without showing the math. Working with the RDP table visually demonstrates how depth, time, and surface intervals interact to affect your body's nitrogen absorption.
The metric version of the RDP offers a few subtle differences from the imperial version: A PDF table allows you to visualize and

The PADI RDP Table Metric PDF is more than just an artifact of scuba history; it is a vital tool for critical thinking, emergency preparation, and foundational dive planning. By understanding the core mechanics of Table 1, 2, and 3, you gain a deeper appreciation for what your dive computer is doing in the background—ensuring you remain a safe, competent, and confident diver wherever your underwater adventures take you.
There are two main versions of the Metric RDP:
