Diving basics
What diving is, pressure, the Red Sea and who can dive.
What is scuba diving?
Breathing underwater from a tank you carry, to explore the sea freely.
Pressure and depth
Every 10 metres adds about one atmosphere of pressure.
Diving in the Red Sea and Egypt
Warm, clear water and some of the richest reefs on Earth.
Who can dive? Medical fitness
Most healthy people can; a short medical questionnaire comes first.
Protect the reef: leave only bubbles
Corals grow a few centimetres a year; one touch can kill them.
Scuba vs. freediving
Freediving is on one breath, with no tank.
