Even if your wrist computer handles live tracking, carrying a digital copy of the metric RDP is highly advantageous:
"You ever wonder," Rafi said while they tightened the last clamp, "who sends these? Why the PDF and not just... call us?"
As they worked—clearing detritus, replacing a section of pipe, coaxing flow back into a gentle, rhythmic breath—the RDP metric crawled upward. The 0.72 ticked to 0.83, then to 0.95. The table in Lela's head reordered: the field's health was not a static row but a living ledger.
It tells you how many minutes of "penalty time" (RNT) you start with due to previous nitrogen, and the maximum time you can safely spend at your next planned depth. Step-by-Step Guide: How to Read the Metric RDP Table
Using the PADI RDP table metric PDF is relatively straightforward. Here's a step-by-step guide: Padi Rdp Table Metric Pdf
For his next dive, he wanted to hit 12 meters to photograph the pygmy seahorses. He flipped the card to Table 3. At 12 meters, starting as a Group F diver, his Residual Nitrogen Time (RNT) was 36 minutes. no-decompression limit
limits. Sliding his finger across Table 1, he found his pressure group:
A safety stop for 3 minutes at 5 meters is highly recommended for all dives, and strictly required any time you dive to 30 meters or deeper, or come within three pressure groups of an NDL.
The PADI (Professional Association of Diving Instructors) Recreative Diving Planner (RDP) Table is a widely used tool for scuba divers to plan and conduct safe dives. The metric version of the table is used to calculate safe depth and time limits for dives. Here's an overview of the PADI RDP Table (Metric) and how to use it: Even if your wrist computer handles live tracking,
Meters (for depth) / Minutes (for bottom time)
Find your new Pressure Group D on the side of Table 3. Match with Depth: Look for 15m along the top of Table 3.
Carrying a physical plastic slate is standard, but having a on your smartphone or tablet is highly beneficial for: Pre-Trip Planning: Checking limits at home before you pack.
Go to . Locate your new Pressure Group D along the side/top. Locate your planned depth for Dive 2, which is . Find the intersection of Group D and . Step-by-Step Guide: How to Read the Metric RDP
(Note: Depths like 12m, 14m, 16m etc., have specific "designated" depths. If you dive to 13m, you must use the next deeper depth (14m) for calculations.)
at the end of every dive, especially if you come within three pressure groups of the No Decompression Limit. Never ascend faster than per minute ( per minute). Why Keep a Digital PDF Copy of the Metric RDP?
A complete should contain:
This table tells you how much "residual nitrogen" you have left and how long you can stay down on your next dive. Use your New Pressure Group from Table 2. Find your planned depth for the next dive.
