Want to dive?

Diving exists for tens of thousands of years! It is an action that has become an evolutionary process! Most likely, it was impossible for the first people to discend into large depths or retain an air for a long time without having any knowledge. Thanks to the evolution of mankind, underwater diving is possible into great depths and duration. Undoubtedly, the history of diving with air retention (apnea), which is also called free diving "in one breath", is far more extensive than SCUBA diving with breathing cylinders. Philippines, Malaysia and Indonesia are the places of the world where the so-called "Nomads of the Ocean" people live who have proven genetic and physical adaptations as a result of evolution. They are descendants whose grandfathers do nothing different from diving all day as it was the only way for them to survive!

Rock Diving recommends you to watch the BBC movie "JAGO" available on, which tells shocking facts about diving.

SCUBA Diving

The basic law of SCUBA Diving reads "Breathe" and that is exactly what you have to do when this extreme sport shows you unseen underwater worlds, provokes your perceptions and unlocks your adventure spirit! Today, its accessibility turns it into a sought entertainment and a popular emotion that creates memories! The continued desire of man for life and knowledge is also the reason of research associated with the seabed, which dates back to the end of the 17th century. However, in the first decades of the 20th century, we can talk about development in diving equipment to turn Scuba Diving into what it is now. The French team of military captain, diver and researcher Jacques Cousteau and engineer Emile Gagnan developed the idea that one can breathe underwater atmospheric air, compressed and stored in pressure cylinders.

Aqua-Lung - the system supplies air under pressured which is equalized to that of the environment. It supplies the diver with air only while breathing. The term originates from its manufacturer. Scaphandre Autonome is the name of the apparatus given by its creators. The year is 1943! This revolutionary invention was followed by the development of another buoyancy compensator, known as the BCD (Boyansy Control Divice) which allowas the diver to control the depth reached during diving;a diving cylinder is attached. Therefrom originates the term "sports diving". Than follow different innovations in the engineering and design of the diving equipment that become more reliable, lighter and convinient.

Improvement and development of SHUBA, which is a self-contained underwater breathing apparatus, and of the overall equipment for underwater diving, transformed the SCUBA diving into a safe and interesting sport of the 21st century!
This is the easiest way for prolonged staying underwater!

SCUBA diving equipment includes several components:

  • Compressed air cylinders
  • Buoyancy compensator - BCD Vest (Boyansy Control Divice)
  • Main and spare breathing regulator
  • Mask
  • Wetsuit
  • Swimfin
  • Weights
  • Accessories

Salinity - water salinity in the water basins is measured in promiles (‰). Through this chemical characteristic, the waters are designated as sweet or salty. The higher the salinity, the more difficult is diving.

  • Black Sea - 18 ‰ l / water
  • Ocean salinity - from 30 to 38 ‰ l / water
  • Mediterranean Sea - from 36 to 39.5 ‰ l / water
  • Adriatic Sea - from 38 to 39 ‰ l / water
  • Aegean Sea - 38.5 ‰ l / water
  • Red Sea - from 38 to 43 ‰ l / water
  • Dead Sea - over 200 ‰ l / water
  • Water is 800 times denser than air
  • The sound under water travels 4 times faster.
  • Water covers 75 percent of the world's surface.
  • The deepest point of the planet is the Mariana Trench - 11 100 m.
  • The maximum depth of the Black Sea is of 2245 m

The most underwater inhabitants for the Northern Black Sea area can be seen at a depth between 5 and 12 m, such as:

  • Bottom fish - turbot, goby, sea scorpion, catfish
  • Pelagics - golden grey mullet, grey mullet, bluefish, sea bass
  • Other - crabs, shrimps, mussels, sea snails
