Padi Rdp Table Metric Pdf Jun 2026

Never exceed an ascent rate of 18 meters per minute (or the rate dictated by your specific dive computer, typically 9-10 meters per minute).

The PADI RDP Table Metric system consists of three main components, often referred to as the "3-Table System." Table 1: No Decompression Limits and Pressure Groups

The in its metric version is a fundamental tool for managing nitrogen absorption and ensuring safety for recreational divers. Unlike Navy tables designed for deep or commercial work, the RDP was the first table created specifically for "no-stop" recreational diving, providing more liberal limits for the multi-level, shallower dives typically enjoyed by sport divers. Core Structure of the Metric RDP

Result: For Group D at 15m, your and your ANDL is 59 minutes . Because your target dive time (25 mins) is less than your maximum limit (59 mins), this dive profile is completely safe. Step 4: Find the Final Pressure Group (Table 1)

Flip to (or scroll to the surface interval section of your PDF). Locate Letter L along the top diagonal row. Padi Rdp Table Metric Pdf

You would then take 52 minutes at 16 meters back to Table 1 to find your next ending Pressure Group. Safety Rules and Guidelines to Remember

Tables never run out of battery or suffer software glitches.

You rest on the boat for 1 hour and 15 minutes .

If you actually dive for 40 minutes at 16 meters, your calculation for your next profile would be: Never exceed an ascent rate of 18 meters

You enter with your Pressure Group letter from your first dive, move across to find your Surface Interval (SI) duration, and exit with a new, lower Pressure Group letter. Table 3: Repetitive Dive Timetable

If your exact depth or time is not on the table, always round up to the next deepest depth or longest time.

The PADI RDP Table is a graphical representation of the safe depth and time limits for scuba dives. It takes into account the principles of decompression sickness and allows divers to plan their dives within safe limits. The table provides a quick and easy way to determine the maximum depth and time for a dive, as well as the required surface interval between dives.

If you buy the PADI Open Water Diver Manual or the PADI Dive Tables (Metric) booklet, they include the full table printed on high-quality paper. This is essentially a "physical PDF." Core Structure of the Metric RDP Result: For

Use a PDF reader app (like Adobe Acrobat or GoodNotes) with a stylus or finger-draw tool. You can draw your dive profiles directly over the tables, map out your paths, and clear the annotations for the next trip. Final Thoughts

The absolute safest source is the official PADI digital ecosystem. If you took an Open Water Diver course digitally, the RDP PDF is usually included in your e-Learning portal.

Many scuba training websites offer free reference copies of the metric chart. Ensure the chart clearly states "Recreational Dive Planner" and features the distinct red, blue, and black grid design.

(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.)
