There’s a bit of physics and physiology involved in a full explanation, but the short answer is: 40 metres/130 feet is the deepest you can dive without having to perform decompression stops on your way back to the surface. How deep can you go in a diving suit? how deep can you go in the ocean without dying.

At what depth do you need decompression stops?

Because they are known to reduce the risk of decompression sickness (DCS), safety stops should be considered standard procedure for all dives below 33 feet (10 m); they should not be considered optional. The depth most commonly associated with the term safety stop is 15-20 feet (5-6 m).

How deep can you dive before worrying about the bends?

The Bends/DCS in very simple terms Anyone who dives deeper than 10 metres (30ft.) while breathing air from a scuba tank is affecting the balance of gases inside the tissues of their body.
