Open Water Diving

In open water diving, diving without visual markers, in a sea with strong currents, can lead to buoyancy problems even for the most experienced diver.

Buoyancy is usually regulated in respect to a fixed point – the seabed, or a reef – but here the diver has to rely exclusively on his depth gauge, that is, his diving computer.

Although speed does not play a significant role during a dive, as it is relatively difficult to exceed the recommended limit of 20 m/ min, it is very important to respect buoyancy regulations during re-surfacing (7-10 m/min). If the dive includes decompression, then it becomes more complex.

It is a good idea to have a fixed, anchored line with a buoy at the surface, which is often found at shipwreck sites, or decompression buoys, which are connected to reels or spools and activated by the diver to ensure safe resurfacing.

Note: Learn how to use decompression buoys under the supervision of a diving instructor as improper usage may endanger your safety.
