air supply. This type of diving feels closest to flying or soaring underwater. The current makes drifting more dangerous than normal diving, as the flow of water can carry divers to the open sea quickly and unnoticed, which is fraught with death. In this regard, it is necessary to have a support team on a fast boat, to have an idea about the direction of the currents at the dive site, and to have a buoy available.

Swamp Diving, Bog Diving - scuba diving in flooded quarries, neglected reservoirs. Belongs to the category of extreme types of diving. Characteristic features - pollution of the reservoir, limited visibility. We are not familiar with "marsh divers", so we can only assume why he needs such a specialization: a) for professional diving; b) for diving for the sake of "fun" (for example, at the World Swamp Diving Championship in the British town of Llanworthy Wales); c) immersion in the harsh reality of modern reservoirs, many of which are littered to a nightmarish state and completely forgotten environmental organizations.

Wall Diving, Drop Off or Wall Diving is diving along steep underwater “cliffs” that go deep (this can be a coral reef or atoll, rock, etc.). Such an underwater wall, covered with corals and other forms of marine life, is a whole bio-system that changes and attracts different inhabitants of the sea, depending on the depth.

Dive Safari, Dive Safari — a safari, a trip to visit dive sites remote from the coast or port. It is characterized by constant residence on a boat equipped for diving, a high frequency of dives (from three to five dives per day). A boat with scuba divers goes to sea for several days: from 3 days to a week or two, during which divers dive in a large number of different places (sites). A dive safari differs from a standard daily dive in the same way that a traditional land safari differs from a visit to a zoo. The essence of this difference is that in a dive safari you travel on a ship with diving in any places that are unattainable during a one-day passage of the ship. The fact is that the most interesting and attractive places are often located far from the coast, as a result - these places are not burdened by an abundance of tourists, and the underwater life is not frightened. The most interesting sunken places and ships can only be seen in this way.

Solo-diving, Solo-Diving - independent diving (alone) using special equipment. The main difference from regular diving is the absence of a second diver (buddy partner) and the use of special equipment. Until recently, solo diving was condemned by the diving community as a particularly dangerous form of diving and has only recently been legalized by the efforts of the SDI diving federation.

High diving and cliff diving is not really about scuba diving, although athletes have to swim in the water. These are the names of jumping into the water from extreme heights (in the case of cliff diving, we are talking about jumping from natural towers - cliffs, rocks).
