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
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.
You can find the PADI RDP Table in metric units in PDF format through various online resources, such as: Padi Rdp Table Metric Pdf
This is the most common question. PADI (Professional Association of Diving Instructors) holds strict copyright over the RDP.
| Section | Use | |---------|-----| | Table 1 – Endurance Limits | Maximum bottom time for a given depth (no decompression) | | Table 2 – Pressure Groups | Letter group (A–Z) after a dive, based on depth & time | | Table 3 – Residual Nitrogen Time (RNT) | Extra “virtual” bottom time due to previous dive | | Table 4 – Repetitive Dive Table | Combines RNT + planned bottom time → final pressure group | The PADI Recreational Dive Planner (RDP) metric version
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.
Since this refers to a specific tool used in scuba diving (the PADI Recreational Dive Planner), this feature breakdown is designed as if we are describing the digitization and presentation of this physical table within a digital application (e.g., a Dive Log app or an Educational tool). While not as granular as the full RDP
pulled the laminated PADI RDP Table (Metric) from his dry bag. To anyone else, it was a grid of numbers and letters—a dense PDF come to life. To Elias, it was the gatekeeper of his morning.
