Introduction

The Recreational 3 (Master Diver) course is a no-decompression helitrox course structured to prepare divers for deeper recreational diving using proper equipment, diving techniques and standard Helium breathing mixtures (standard gases).

Recreational 3 training continues the Essentials of Recreational Diving and Recreational 2 (Advanced Diver) or equivalent skills and is designed to cultivate, integrate and expand those skills required for safer deeper recreational diving.  The course will incorporate more advanced decompression theories and the use of correct ascent procedures along with problem identification and resolution while building the capacity for progressively more challenging diving.  In this course, students will be trained in:  the use of single or double cylinders and in the potential failures associated with them; the use of nitrox and helitrox for extended bottom times; and the use of helium to minimize narcosis, CO2, gas density and post dive "nitrogen stress."

The Recreational 3 course is normally conducted over a 2 to 4 day period, and cumulatively involves a minimum of 24 hours of instruction including academics, confined water, and open water dives to 130’/39m using Helitrox 25/25 as a breathing gas.  The final dives are “experience dives,” where you will use your new skills while being shadowed by your instructor.

Course Information

The Recreational 3 course is designed to provide a working knowledge of nitrox and helitrox, including history of decompression and practice, physics, physiology, tables, (deco planning software) and operational considerations.

Course requirements include six hours of academics and 6 dives, 4 will be critical skills training dives and the last 2 will be experience dives deeper than 100’/30m.  A Rescue & Emergency Procedures course must be completed prior to the certification being issued.  The initial two critical skills dives will be conducted in water no deeper than 40'/15m to evaluate the diver’s ability and to identify any deficiencies in critical skills.  The two experience dives are helitrox dives at depth, but not in excess of course depth limitations.

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.
