Rdp Table Metric Pdf | Padi

The short answer: No. You will waste hours searching for a file that either doesn't exist legitimately or is too poor quality to trust your life with.

The practical solution: Spend the $15 to $30 on the official PADI eRDP (digital) or the waterproof plastic table. Your safety is worth more than the price of a few tank fills. If you are simply studying for an exam, your dive instructor likely has a high-resolution digital copy they can share specifically for classroom use.

Remember: Dive tables are life-support equipment. Use the metric system properly—calculate your meters and minutes carefully—and always plan your dive, then dive your plan.

The PADI Recreational Dive Planner (RDP) Table (Metric) is a critical tool for scuba divers to manage nitrogen absorption and avoid decompression sickness (DCS). Unlike the Imperial version, which uses feet, the metric table is designed for depths measured in meters.

Whether you are studying for your Open Water Diver exam or need a reliable backup for your dive computer, understanding how to read the three main tables is essential. Core Components of the Metric RDP Table

The RDP consists of three interconnected tables used to track your Pressure Group (PG)—a letter from A to Z representing the theoretical amount of residual nitrogen in your body.

Table 1: No Decompression Limits and Pressure GroupsUsed to find your PG after a single dive. It lists depths from 10m to 42m.

Table 2: Surface Interval Credit TableShows how much nitrogen leaves your body while you are on the surface. The longer the surface interval, the lower your next PG will be.

Table 3: Repetitive Dive PlanningProvides the Adjusted No Decompression Limit (ANDL) for your next dive, accounting for the nitrogen still in your system. Step-by-Step: How to Use the Metric RDP

The PADI Recreational Dive Planner (RDP) metric version is a specialized tool used by scuba divers to calculate No Decompression Limits (NDL) and track nitrogen absorption across multiple dives. Unlike the imperial version, which uses feet, the metric table uses meters (m) to represent depth. 🛠️ Core Functions of the Metric RDP

The planner consists of three primary tables designed to be used in sequence: Table 1: No Decompression Limits

Finds the maximum time allowed at a specific depth for a first dive.

Assigns a Pressure Group letter (A–Z) based on depth and time. Table 2: Surface Interval Credit

Tracks how much nitrogen "off-gasses" while you are on the surface.

Assigns a new, lower Pressure Group based on your time out of the water. Table 3: Repetitive Dive Timetable

Calculates Residual Nitrogen Time (RNT) from previous dives.

Provides the Adjusted No Decompression Limit (ANDL) for your next dive. 📏 Key Metric Limits & Rules

When using the metric table, divers must adhere to specific rounding and safety rules:

Depth Rounding: If your exact depth is not on the table, always round up to the next greater depth (e.g., 11m becomes 12m). The short answer: No

Time Rounding: If your exact dive time is not shown, round up to the next value.

Maximum Depth: The recreational limit for most dives is 40 meters. Open Water divers are typically limited to 18 meters.

Safety Stops: Recommended for all dives at 5 meters for 3 minutes. They are mandatory if you come within three pressure groups of a limit. 🔄 Metric vs. Imperial Differences

While the planning method is identical, the values differ slightly due to rounding: Metric System Imperial System Depth Unit Meters (m) Max Depth Safety Stop NDL Example (10m/33ft) 219 minutes 205 minutes

Note: Never mix metric and imperial tables for the same dive series, as nitrogen tracking will become inaccurate. 💾 Essential Definitions

Actual Bottom Time (ABT): The total time spent underwater during a single dive.

Residual Nitrogen Time (RNT): Theoretical minutes added to a dive to account for nitrogen still in your body. Total Bottom Time (TBT): The sum of ABT and RNT ( ), used to find your final Pressure Group. The duration of that dive

How long you plan to stay on the surface before the next dive

Title: PADI Recreational Dive Planner – Metric Version (eRDPML / Table)

Version: Standard 3rd Generation (as taught in PADI Open Water Diver course)

Units: Meters (for depth) / Minutes (for bottom time)

Format: PDF (printable, high-resolution, tablet-friendly)

Purpose:
The PADI RDP Table Metric PDF provides divers with a proven, battery‑independent method for planning no‑decompression dives. It allows you to calculate allowable bottom times, required surface intervals, and residual nitrogen levels when diving with air (21% oxygen).

Students typically search for this exact keyword for three specific reasons:

Crucial Warning: PADI actively protects its intellectual property. Legitimate, full-resolution PADI RDP Table Metric PDFs are generally not available for free distribution. Most links you find on Reddit, forums, or file-sharing sites are either low-resolution, watermarked, or (most dangerously) outdated versions that can give you incorrect dive times.

PADI offers a free app that includes a basic dive planner. While not as granular as the full RDP table, it is useful for quick checks.

To obtain a legal PDF or physical copy of the Metric RDP, you should:

You might wonder, "My dive computer does the math. Why do I need the Padi Rdp Table Metric Pdf?"

To plan a second dive, you use the "Rule of Thirds" or the table on the back/bottom of the card to calculate Residual Nitrogen Time.
