A safety stop is a short, relaxing pause near the end of a dive that adds a big margin of safety for almost no effort. You hover at around five meters for about three minutes before finishing your ascent, giving your body extra time to gently release the nitrogen it absorbed at depth. It is not a rescue measure or a sign anything is wrong; it is simply a smart habit that good divers do on every dive. At Nautilus we make it part of the routine, and it often doubles as a final, unhurried look at the reef.
Why we pause
During a dive your body absorbs extra nitrogen from the air you breathe, and it needs to release that gas slowly as you return to the surface. A slow ascent handles most of this, but pausing at shallow depth gives your body a helpful bonus of extra off-gassing time.
Think of it like slowing gently before a stop sign rather than slamming the brakes. Those three quiet minutes let the last of the dissolved nitrogen leave safely, sharply lowering the already small risk of decompression sickness.
How to do it well
A safety stop is easy once your buoyancy is steady, and it is great practice for hovering. The steps are simple and become automatic within a few dives.
- Ascend slowly to about five meters as your dive winds down.
- Hover in place using small BCD and breathing adjustments, staying as still as you can.
- Watch your dive computer or time it for three full minutes.
- Then rise the last few meters slowly, breathing continuously, until you break the surface.
A moment to enjoy
Far from being a chore, the safety stop is one of the nicest moments of a dive. Hanging weightless in the bright, shallow water, you often get a last visit from curious fish or a passing turtle before you go up.
In the clear, warm water of Isla Fuerte, with visibility that stretches across the reef, those three minutes at five meters can feel like the calm reward at the end of the adventure. Many divers say it is their favorite part.
Part of every dive here
We build a safety stop into every dive at Nautilus, so it becomes second nature from your very first outings. Our guides signal the group, keep everyone together at the right depth, and time it for you.
Because our profiles are relaxed and conservative, this simple routine keeps your diving comfortably inside every limit. See how we run our dives, from beginner reefs to deeper sites like Bushnell, on our courses and dives page.
