PADI Tec 40 course bridges the gap between recreational and technical diving. It is ideal for Advanced Open Water Divers with at least 30 logged dives. During this course, you’ll get familiar with technical equipment, dive planning, and basic decompression techniques for dives up to 40 meters.

You’ll learn how to handle new configurations, perform gas planning, and manage risks underwater. Tec 40 also serves as a solid foundation for the next levels — Tec 45 and Tec 50.
