Padi Rdp Table Metric Pdf (2026)

This side calculates your new Pressure Group after resting on the surface.

| Pressure Group | Depth (m) → RNT (min) | |----------------|------------------------| | Example: Group E | 12m → 12 min RNT
15m → 19 min RNT
18m → 26 min RNT |

RNT = additional “imaginary” bottom time from previous dive.

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). Padi Rdp Table Metric Pdf
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

A very specific topic!
The PADI RDP (Residual Nitrogen Time) Table, also known as the Recreational Dive Planner, is a tool used by scuba divers to plan safe dives and avoid decompression sickness. Here is an informative text regarding the PADI RDP Table in metric units (depth in meters and time in minutes):
What is the PADI RDP Table?
The PADI RDP Table is a table that helps divers plan safe dives by calculating the maximum allowed dive time for a given depth, based on the amount of residual nitrogen in their body. The table takes into account the depth and time of previous dives, as well as the surface interval between dives.
How to use the PADI RDP Table (Metric Version)
The metric version of the PADI RDP Table is used as follows:

Here are some sample values from the PADI RDP Table (metric version):
| Depth (m) | Single Dive Time (min) | Repetitive Dive Time (min) |
| --- | --- | --- |
| 10 | 55 | 45 |
| 15 | 40 | 35 |
| 20 | 30 | 25 |
| 25 | 20 | 18 |
| 30 | 15 | 12 |
Understanding the PADI RDP Table
The PADI RDP Table provides a conservative approach to dive planning, helping divers avoid excessive nitrogen absorption and reduce the risk of decompression sickness.
When using the table, keep in mind:

Make sure to verify the authenticity and accuracy of the table, as incorrect information can lead to serious safety risks.
By understanding and using the PADI RDP Table (metric version), divers can plan safe and enjoyable dives while minimizing the risks associated with scuba diving.
The PADI Recreational Dive Planner (RDP) Metric Table, developed by DSAT, is a tool for managing nitrogen absorption during no-stop dives up to 40 meters, utilizing pressure groups from A to Z to calculate residual nitrogen. The system consists of three tables for managing, calculating, and planning repetitive dives, requiring divers to always round up depth and time to the next greater value.

PADI Recreational Dive Planner (RDP) (Metric version) is a specialized decompression table designed specifically for no-stop recreational diving. Unlike older tables like the US Navy versions, the PADI RDP was developed by Diving Science and Technology (DSAT) to better account for the nitrogen absorption patterns seen in multiple, repetitive dives. Core Function and Structure
The RDP consists of three interconnected tables used to calculate safe "no-decompression limits" (NDLs), which is the maximum time a diver can stay at a specific depth without requiring decompression stops during ascent. Table 1: No-Decompression Limits & Group Designation : Maps your depth and time to a Pressure Group
(a letter from A to Z) representing the amount of residual nitrogen in your body. Table 2: Surface Interval Table
: Shows how much nitrogen leaves your body during a break on the surface. You enter with your ending pressure group and exit with a new, lower pressure group based on time spent out of the water. Table 3: Repetitive Dive Timetable : Used to find your Residual Nitrogen Time (RNT)
, which must be added to your actual planned dive time for your next dive to ensure you don't exceed safety limits. goprocaribbean.com Key Safety Rules for the Metric RDP
Navigating the PADI RDP Table: A Metric Guide for Divers Whether you are a new PADI Open Water Diver or a seasoned pro, the Recreational Dive Planner (RDP)
remains the gold standard for understanding nitrogen management. While most of us rely on dive computers today, knowing how to use the metric RDP table
is a foundational skill that ensures you can plan your dives safely, even if your tech fails.
This guide breaks down the metric version of the RDP table, providing the essential steps to keep your dives within No Decompression Limits (NDLs) Why Use the Metric RDP Table?
The metric RDP is used in most of the world to track nitrogen absorption in meters and minutes. It helps you: Calculate NDLs
: Determine the maximum time you can stay at a specific depth without requiring a decompression stop. Track Pressure Groups This side calculates your new Pressure Group after
: Use letter designations (A–Z) to monitor residual nitrogen. Plan Repetitive Dives
: Account for nitrogen remaining in your system from previous dives. Core Rules for Using the Table Padi Rdp Table Metric Pdf [updated]
The PADI Recreational Dive Planner (RDP) metric version is a set of three tables used to calculate no-decompression limits (NDLs) and manage nitrogen levels for scuba diving. Core Tables Overview
The metric RDP is divided into three interconnected sections:
Table 1: Single Dive Planning – Provides NDLs for depths up to 42 meters and assigns a Pressure Group (PG) letter (A–Z) based on dive time and depth.
Table 2: Surface Interval Credit – Shows how your Pressure Group changes as you off-gas nitrogen during a surface interval (SI).
Table 3: Repetitive Dive Planning – Gives the Adjusted No-Decompression Limit (ANDL) and Residual Nitrogen Time (RNT) for subsequent dives based on your current Pressure Group. Critical Rules for Use
To ensure safety, you must strictly follow these table rules:
Round Up Only: If your exact depth or time is not listed, always use the next higher (deeper or longer) value.
Safety Stops: Required if you dive to 30 meters or deeper, or if your dive ends in a gray box on the table.
Descent/Ascent Rates: Maintain a steady descent rate and an ascent rate no faster than 18 meters per minute.
The "Rule of 9": It is strongly recommended to make each successive repetitive dive shallower than the one before it.
WXYZ Rule: If you end a dive in pressure groups W or X, a minimum surface interval of 1 hour is required. For Y or Z, the minimum is 3 hours. Key Planning Metrics PADI RDP TABLE - Table Met | PDF | Scuba Diving - Scribd
