Start Your Technical Diving Journey with the Tec 40 Course

The Tec 40 course is the first step into the world of technical diving. Designed for advanced recreational divers who are ready to explore beyond traditional no-decompression limits, this course bridges the gap between recreational and full technical diving. You’ll learn how to use decompression software, plan extended bottom times, and dive with backup equipment in environments requiring increased precision, discipline, and responsibility.

With hands-on training and real-world diving scenarios, the Tec 40 course provides both the confidence and competence to dive safely and progressively. Set against the stunning backdrop of Roatan and its legendary reef walls and wrecks, this is where your technical diving evolution begins.

What You’ll Learn

• Use of dive planning software and multigas dive computers
• How to manage a decompression dive to a maximum of 40 meters
• Use of a single decompression gas up to 50% oxygen
• Gear configurations for technical diving (including sidemount or backmount)
• Gas planning, equipment redundancy, and emergency procedures
• Proper ascent procedures, gas switches, and problem-solving

Why Choose This Course?

• Ideal for divers interested in technical diving but not ready for full trimix depth
• Allows progressive skill development without overwhelming students
• Taught by experienced Tec instructors with thousands of dives
• Access to world-class dive sites like Roatan’s wrecks and deep walls
• Flexible configuration options (sidemount or backmount available)

Whether you’re planning to continue to Tec 45 or simply want to extend your recreational limits with decompression experience, the Tec 40 course gives you a solid foundation.
