Who could imagine for a minute that Namibia is a diving destination?

The Hernando County Sheriff's Office has reported that Dillon Sanchez (15) and his father Darrin Spivey (35) were trying out new dive equipment Sanchez had received as a Christmas present. The pair visited the Chassahowitzka National Wildlife Refuge on Christmas morning and dived Eagle's Nest Sink cave.

Years of preparation finally paid off on 3 August 2013 when the first Belgian cave diving team reached deeper territory in Ressel Cave in Lot, France.

Diving the Ojamo lime mine in Finland, 138 meters of water, 4°C.

Two buddies are holding the line. The second is holding the arm of the one leading the way, communicating with him by means of touch. With visibility nil, the first buddy protects his head and face with his hand in case of contact with a wall or rock. Suddenly, for some unknown reason, the line moves and goes out of their hands. They search for it but to no effect. Their mistake: they were not holding the line properly. Will they panic? No. Their nearby instructor stops the exercise. The entire scenerio took place on dry land

A rusty tram clatters past us. An uninterrupted line of cars slowly moves along Leó Frankel Street. Businessmen in dark suits hurry to their desks. Women in high heels walk carefully on the cobbled pavement. Between the houses, the ferries on the Danube can be seen, drifting past the Isle of Margaret that divides the town. We are in the middle of the Budapest morning rush hour. Our team attracts attention from passersby. We are carrying a van load of diving bottles and boxes through a narrow iron gate. The stone wall next to the cave is soon covered by diving equipment.
