Leszek Czarnecki
Getting his licence at the age of 22, in the early 1980s, Leszek Czarnecki was one of the youngest diving instructors in Poland. In 1986, his passion for cave diving led him to set up his first commercial diving company —Przedsiębiorstwo Techniki Alpinistyczno-Nurkowej TAN S.A. In 1986–1990, he worked as a professional diver (with heavy diving equipment for underwater works). Diving is still his passion. He holds two – Polish and world – records. In September 2003, he beat the Polish record diving to 194 m in Boesmansgat cave in South Africa. The decompression lasted 4 hours and 48 minutes, at a water temperature of 16 °C. He was assisted by Nuno Gomes who holds two deep sea diving records – in the open sea he dived to 318.25 metres, and in caves – to 283 metres. In Mexico, Leszek Czarnecki beat the world record in the longest distance covered in the caverns – 17 km in the system of water-filled caves Dos Ojos on the Yucatán Peninsula in Mexico. In 2006, he took part in a North Pole expedition, and in a Bikini Atoll expedition to explore the wrecks. In 2007, he went on a trip across Siberian wilderness with diving in Lake Baikal, in 2008 – he went to Antarctica, and in 2010 – explored wrecks in the Truck Lagoon in Micronesia (where he dived several times), and in Galapagos.
