You now plan a dive to 18 meters.
To obtain a legal PDF or physical copy of the Metric RDP, you should:
This side calculates your new Pressure Group after resting on the surface.
Whether you find a PDF or buy the physical table, the logic is identical. The Metric version measures depth in meters and time in minutes. Here is how to plan a single recreational dive.
PDFs floating around the internet are often scanned at 72 DPI. The RDP tables rely on tiny numbers for Residual Nitrogen times. If the PDF is blurry, you might misread 31 minutes as 37 minutes, leading to an erroneous plan.
A complete PADI RDP Table Metric PDF should contain:
The Padi Rdp Table Metric Pdf is more than a piece of paper; it is a fundamental safety tool. While digital apps are convenient, a physical or printed backup ensures you are never caught off-guard.
Action Steps:
Dive safely, plan your dive, and dive your plan—in meters, with the Metric RDP.

This informative post provides an overview of the PADI Recreational Dive Planner (RDP)
in its metric table format, which is essential for planning safe, no-decompression dives. Understanding the PADI RDP Metric Table Recreational Dive Planner (RDP) was developed by Diving Science & Technology (DSAT)
specifically for recreational, no-stop diving. Unlike traditional tables, it is designed to maximize dive time for those making multiple dives in a single day. Key Components of the Table The RDP is comprised of three distinct but linked tables: Table 1 (Front): Used to determine your Pressure Group (PG) after a dive based on depth and time. Table 2 (Back): Used to calculate your new Pressure Group after a Surface Interval (SI) Table 3 (Back): Used for repetitive dive planning to find Residual Nitrogen Time (RNT) Adjusted No Decompression Limits (ANDL) Standard Rules for Metric Planning
When using the metric version of the table (measured in meters and minutes), keep these safety rules in mind: Rounding Up: Always use the exact or next greater depth and time shown on the table. Shallow Dives: Treat any dive to 10 meters or less as a 10-meter dive. Ascent Rate: Never exceed an ascent rate of 18 meters per minute. Safety Stops:
A 3-to-5-minute safety stop at 5 meters is recommended for all dives and required for any dive to 30 meters or deeper. Repetitive Dives:
Limit all successive dives to 30 meters or shallower and always plan the deepest dive first. Step-by-Step Example (Metric) Imagine you are planning a first dive to 30 minutes Find Depth: Since 17m isn't on Table 1, round up to the Find Time: Padi Rdp Table Metric Pdf
Follow the 18m column down to find 30 minutes. (If 30 isn't there, use the next higher number, such as 32). Identify PG:
Move horizontally to the right to find your Pressure Group letter. At 18m for 30 mins, your ending Pressure Group is Resources for Download

Understanding the PADI RDP Table (Metric) for Safe Scuba Diving
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:
What is the PADI RDP Table?
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.
Understanding the Metric RDP Table
The metric RDP Table uses meters for depth and minutes for time. The table consists of a series of columns and rows that represent different depths and times. The columns represent the maximum depth of the dive, and the rows represent the dive time.
How to Use the PADI RDP Table (Metric)
To use the PADI RDP Table (Metric), follow these steps:
Key Concepts
Example Use Case
Suppose you plan to dive to a maximum depth of 18 meters for 40 minutes. Using the PADI RDP Table (Metric), you would:
Downloadable PDF Resources
You can find downloadable PADI RDP Table (Metric) PDFs online, which provide a convenient reference for planning dives. These resources often include instructions on how to use the table and examples of how to plan safe dives.
Conclusion
The PADI RDP Table (Metric) is a valuable tool for scuba divers to plan and conduct safe dives. By understanding how to use the table, divers can minimize the risk of decompression sickness and enjoy a safe and enjoyable diving experience.
You can find more information and downloadable resources on the PADI website or other scuba diving websites.
The Recreational Dive Planner (RDP) is an essential tool for any scuba diver. Developed by PADI (Professional Association of Diving Instructors), it helps divers calculate their remaining Nitrogen limits to avoid Decompression Sickness (DCS).
While many modern divers use dive computers, understanding the Padi Rdp Table Metric Pdf is a core requirement for passing the Open Water Diver course. It serves as a vital backup and teaches the fundamental science of gas absorption. 📘 Understanding the PADI RDP Table (Metric)
The metric version of the RDP uses meters for depth and minutes for time. Unlike the US Imperial version (feet), the metric table is the global standard for most diving destinations outside the United States. The Purpose of the RDP Prevent DCS: Keeps you within "No Decompression" limits.
Track Nitrogen: Assigns a "Pressure Group" (letter A–Z) based on nitrogen levels.
Plan Surface Intervals: Calculates how much nitrogen leaves your body while on the boat.
Calculate Multiple Dives: Adjusts your limits for second or third dives in a single day. 🛠️ How to Read the Three-Table System
The PADI RDP is comprised of three distinct tables, usually printed on two sides of a waterproof card or available as a digital PDF. Table 1: Dive Profile & Pressure Group
This table correlates your Maximum Depth with your Actual Bottom Time. Find your depth at the top. Follow the column down to your dive time.
Follow the row to the right to find your Pressure Group letter. Table 2: Surface Interval Credit Nitrogen leaves your body as you breathe at the surface. Find your Pressure Group from Table 1. You now plan a dive to 18 meters
Follow the row until you find a time range that includes your Surface Interval (the time you spent out of the water). Follow the column down to find your New Pressure Group. Table 3: Repetitive Dive Timings
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.
The intersection provides two numbers: Residual Nitrogen Time (RNT) and Adjusted No Decompression Limit (ANDL). 📏 Key Terms to Remember
No Decompression Limit (NDL): The maximum time you can stay at a depth without needing a decompression stop.
Pressure Group: A letter representing the theoretical amount of nitrogen in your tissues.
Safety Stop: A 3-minute pause at 5 meters, required for dives deeper than 30 meters or when approaching NDLs.
Bottom Time: Total time from the start of the descent to the beginning of the final ascent. 📥 Why You Need a PDF Version
Carrying a physical plastic slate is standard, but having a Padi Rdp Table Metric Pdf on your smartphone or tablet is highly beneficial for: Pre-Trip Planning: Checking limits at home before you pack.
Study Aid: Practicing "find the Pressure Group" problems for the PADI exam.
Emergency Backup: A digital copy ensures you are never without a planning tool if your computer fails. ⚠️ Important Safety Limitations The RDP is designed for recreational diving only. Never exceed the "blacked out" areas of the table. Avoid "yo-yo" diving (going up and down repeatedly).
Ascent Rate: Always ascend slower than 18 meters per minute.
Altitude: These tables are not for dives above 300 meters elevation.
