TDI Cavern Course

Day 1 – Theory & Equipment Workshop
You start with a comprehensive theory session on dive planning, gas management, communication, line handling, and emergency management. Afterwards, we will look in detail at the specific equipment used in Cavern Diving – including all lighting systems, redundant breathing gas supply, and guide lines.

Day 2 – Open Water Skills
Before entering the cave, we will practice the fundamental techniques in open water: buoyancy, trim, precise movements, line work, light signals, and team communication. Emergency drills such as gas loss or loss of visibility are also on the agenda.

Day 3 – First Dives in the Cavern Zone
Before we make the first dives, we must first learn how to lay a permanent line in the cavern areas. The third day is dedicated to line work, team communication, and gas management.

Day 4 – Deepening & Final Dives
On the last day, exciting dives with scenario training are on the agenda – such as navigating in case of light failure when exiting the cavern zone or line entanglements. Finally, we will jointly analyze your progress and discuss your next possible steps in technical or cave diving.
