Advanced Nitrox/Extended Range

Tech Diver TrainingWhether staying longer, going deeper, breathing a richer gas or penetrating overhead environments, this is the beginning of a whole new realm of underwater adventure. This program introduces the academic knowledge, equipment, skills and techniques needed to plan and conduct dives beyond the traditional recreational depth limits with simulated stage decompression.

Full technical training is an equipment- and skill-intensive endeavor. Considerable classroom sessions and in-water practice of skills are necessary. Emphasis is on diving physics and physiology and the equipment and skills necessary to conduct yourself safely in a wide variety of underwater situations.

Entering the extended-range or technical realm is a big commitment. These dives are usually mission-oriented and require more preparation and planning. Buoyancy control and proper propulsion techniques must be mastered. Most important is the right mind-set in the form of self-sufficiency and situational awareness.

Tech Divers

Contrary to stereotypes, true technical divers are not hard-core risk takers who brag. On the contrary, good technical and extended-range divers are fully aware of their capabilities and their limitations. They train and educate themselves for the diving excursion at hand, equip themselves properly and know not to take Mother Nature for granted. These divers are part of a team where each has a specific duty.
