Having completed your Essential Tech course, you’ve already train the necessary skills to go deep. Now it’s time to add a stage bottle to your setup to enhance your safety and bottom time.

TEC 40 or Advanced Nitrox

Course

The goal of this course is to continue practicing your technique, but now with the addition of a stage bottle. We will conduct deep dives, but without decompression.

The importance of starting to dive with a stage tank without deco will help you to manage your dive plan, times, communication, and technique before you go to deco dives.

In this course, we will use Nitrox up to 40% as the bottom gas to improve safety.

This course can be combined with the Nitrox specialty course.

Prerequisites:

• Advanced Diver certification (or equivalent).

• Certification in Essential Rec (Single Tank), Essential Tec (Twinset), or Essential Sidemount (or equivalent).

• At least 30 logged dives, with 10 of them deeper than 25 meters.

• Nitrox Diver certification (or equivalent).

• Diver Medical Declaration.

• Mandatory Accident Insurance (covering up to 40 meters).
