Introduction

The Technical 2 course is designed to continue a diver’s pursuit of technical diving, giving them the ability to use hypoxic trimix blends and to carry and manage 2 decompression bottles (Nitrox 50 and 100% Oxygen).  New material includes the nuances of trimix (hypoxic mixes), gas management and failure management of multiple decompression bottles, in-water management of these two decompression bottles, and other academic issues and understanding of the dives to 200'/60m.

Successful completion of Technical 2 qualifies a diver to use trimix 18/45 and 15/55 to 200'/60m utilizing up to 2 decompression bottles with a maximum of one hour of decompression using nitrox mixes up to and including 100% Oxygen.

Course Information

This course is structured around a 4 consecutive-day structure.  Technical 2 involves a minimum of 6 hours of classroom instruction and 6 dives:  4 training dives and 2 experience dives with trimix.  All dives are conducted using two deco bottles.  The course is designed to provide a working knowledge of trimix, including an understanding of the history and practice of decompression, physics, physiology, table analysis, ratio deco (deco on the fly) and operational considerations.  This course is a decompression course, so divers in this depth range must be aware of the potential for entering into decompression commitments and should be prepared.

Equipment Requirements

Prior to the commencement of the course, students should consult with a UTD representative to verify equipment requirements.  All participants are responsible for providing all equipment or for making provisions to secure all necessary equipment before the start of the course.

In general, it is better for the student to learn while using their own equipment.  However, students should exercise caution before purchasing new equipment to avoid acquiring substandard or unnecessary equipment.  Please contact us prior to making any purchases.
