Three-Minute Stop
Definition
The three-minute stop is a recommended safety stop at 15 feet (5 meters) after a dive to reduce decompression risk.
More on Three-Minute Stop
Also called a safety stop, the three-minute stop is performed near the surface—typically at 15 feet—for at least 3 minutes at the end of most recreational dives. It helps off-gas residual nitrogen and adds an extra safety buffer. While not mandatory if no-decompression limits weren’t exceeded, safety stops are strongly advised and taught as best practice. Divers often hold onto a line or DSMB to maintain depth, especially in current or low visibility conditions.
Frequently Asked Questions
No, but it’s strongly recommended after most dives, especially deeper than 30 feet.
Use a line, hold a DSMB, or control buoyancy precisely to stay at 15 feet for the full duration.
You increase the risk of decompression sickness, especially after deep or repetitive dives.
It’s a good habit, even on shallow dives. It builds discipline and provides a margin of safety.
Yes. Most modern dive computers prompt you when and how long to stop based on your dive profile.
