The difference between leisure and technical diving

The rigorous question actually has no absolute answer. Different people have different understandings of this issue. If we do not consider the purpose and the commercial situation for the time being, and according to the restrictions, and the method of behavior to distinguish, it will be relatively clear.

Recreational diving:

Recreational diving is defined as the use of oxygen or high oxygen (up to 40%) for no-decompression diving with a maximum depth of no more than 40 meters. In infiltration diving, you need to dive in areas where there is natural light injection or where the total length does not exceed 40 meters. This usually means that with relatively simple equipment (single cylinders and regulators), it can quickly rise to the surface in an emergency and does not require complicated training. Due to its simplicity, it is particularly suitable for a wide range of people.

Technical diving:

Unlike traditional recreational and business diving and search diving, it is further defined as more nature. Technical diving more than 40 meters above, need to stage decompression, in the closed space more than 40 meters away from the water surface, use 40% -100% pure oxygen for accelerated decompression, and use different gas mixtures in the dive. Technical diving extends the theory of diving methods, technical theory, and training to deal with and manage increased risks. So this usually means using relatively complex equipment to dive in situations where the problem of decompression cannot be raised directly to the surface. It also means diving in an environment where it is not possible to rise directly to the surface of the water because the physical conditions do not permit it, such as shipwrecks or caves. This shows that technical diving requires relatively complex and extended training requirements and has certain physical and psychological requirements. These are technical diving only limited to a small portion of divers.

Technical diving has a broader definition of space than casual diving, and you can define many different forms of diving as technical diving. However, the simple limit of expansion is not technical diving. For example, if you use recreational diving equipment and behave in a manner that drops to 50 meters, diving is not technical diving. It can only be called silly.
