Using the PADI RDP table metric PDF is relatively straightforward. Here's a step-by-step guide:
A grid of entry pressure groups and exit pressure groups intersected by time ranges (in hours and minutes).
Let's walk through a typical two-dive scenario using a metric RDP table. Dive 1: The Profile 18 meters Planned Bottom Time: 30 minutes Look at Table 1 and locate the 18m column. Padi Rdp Table Metric Pdf
(Full table is grid: depth vs time → letter group A (lowest) to Z (highest nitrogen load).)
Find your current on the top horizontal axis. Find your planned depth of 15 meters on the vertical axis. Locate the intersection box for Group D and 15m . Reading the Box: Using the PADI RDP table metric PDF is
Do you have a specific dive profile in mind that you'd like to calculate?
If your depth is 15 meters, use the 16-meter column. If your time is 26 minutes and the table jumps from 25 to 27, use 27 minutes. Dive 1: The Profile 18 meters Planned Bottom
For example, the NDL for a dive to 18 meters is 56 minutes, while at 40 meters, it drops to just 9 minutes.
The Recreational Dive Planner (RDP) is one of the most revolutionary tools in scuba diving history. Developed by the Diving Science and Technology (DSAT) corporate affiliate of PADI, it safely extends bottom times for recreational divers. While modern dive computers have largely taken over real-time tracking, understanding the PADI RDP Table Metric PDF remains a foundational skill for safety, dive planning, and backup redundancy.
The maximum time allowed at a specific depth without requiring a decompression stop.
