To become a skilled cave diver, there are five essential training courses. These include the Cavern Diver, Intro to Cave Diving, Full Cave Diver, DPV Cave Diver, and Stage Diver courses. Each course focuses on different skills, especially buoyancy control, which is vital in cave environments where small depth changes are significant. Beginners should practice in high-flow caves, which help minimize silt and improve awareness. Learning to adapt to various challenges prepares divers for different underwater experiences.
