Scuba diving No-Decompression Limits (NDL) tables

The No-Decompression Limit (NDL) is the maximum time a diver can spend at a specific depth without requiring mandatory decompression stops during ascent. Staying within NDL allows divers to ascend directly to the surface (with a safety stop) without risking decompression sickness.

Understanding and respecting NDL times is fundamental for recreational diving safety and is typically displayed on dive computers based on the diver's depth and gas mixture.
