What is the maximum depth that a scuba diver, a submersible or a submarine can dive?

Anyone who wants to practice diving must be prepared, both mentally and physically, for what they are going to do. Many factors must be taken into account, such as the oxygen level or the pressure that can be reached by descending beneath the sea’s surface.

How deep can a diver go?

First of all, it is necessary to ascertain whether the diver is going to go with or without equipment. For the vast majority of free divers, the depth is around six meters. In the event that there is a considerable effort and, above all, a lot of discipline, it is possible to reach 12 meters deep though the world record is much more.

Techincal diving involves using specialised equipment and procedures to dive deeper than recreational limits. Depending on the level of technical certification and equipment configuration, technical divers can reach depths ranging from 40 meters to several hundred meters.

Advanced technical divers may explore depths beyond 100 meters, but these dives require extensive training and experience due to increased risks and complexities.

What is the maximum depth to which a submarine can descend?

Submarines usually descend between 400 and 500 meters on average. In any case, they do not usually exceed 600 in order to be completely in the water, they must have a density greater than that of the liquid element.

A kind of tank known as ballasts are usually used, which are located in the front and rear areas of the boat, and whose function is to ensure that the density be greater than that of water.

How deep can submersibles go down?

Submersibles have been manufactured that have been able to descend to below 10,000 meters, despite of elements such as the lack of oxygen or the high levels of pressure that this type of vessel faces. The Spanish craft, DSV Limiting Factor has the greatest record, as it was able to descend to 10,706 meters in the Mariana Trench back in 2021.
