GUE Recreational TriOx course is geared towards divers who want most safety and enjoyment out of their deeper recreational diving, conducting no-decompression dives in the 24-36m range focusing on non-accelerated decompression diving.

The GUE Recreational TriOx class, structured for deeper recreational diving, will explore the use of different breathing gases, including nitrox and triox (triox is a helium-oxygen-nitrogen mix with oxygen content greater than or equal to 21%) for extended bottom times. In addition the Recreational TriOx class will address many of the failures that can occur during deeper diving and teach the students how to resolve those problems, amplifying the skills learned in Fundamentals of DIR

Whether you are a advanced diver or a seasoned diver with multiple dives, incorporating the use of Helium and DIR principles into your deeper diving activities allows you to maximize diving fun and safety. GUE's Rec TriOX, is the opening to the most advanced forms of technical diving.

Prerequisites

1.     Must meet GUE General Course Prerequisites as outlined in Section 1.6.

2.     Must be a minimum of 18 years of age.

3.     Must have taken GUE DIR Fundamentals or a GUE Cave, Tech or Rebreather class.

4.     Must have a minimum of 50 dives beyond open water qualification, 25 of which must be non-training dives.

5.     Must be able to swim a distance of at least 15 meters on a breath hold.

6.     Must be able to swim at least 275 meters in less than 14 minutes without stopping.

Course Content

The GUE Recreational TriOx course is normally conducted over a 7-day period, and cumulatively involves a minimum of 30 hours of instruction, designed to provide a working knowledge of Nitrox and TriOx, including an understanding of the history and practice of decompression, physics, physiology, tables, and operational considerations.

Course requirements include 4-evenings of academics and twelve (12) dives, eight (8) of which will be critical skill dives and four (4) will be experience dives as defined in the GUE Standards and Procedures.

The initial eight (8) dives will be conducted in water no deeper then 40 feet to evaluate the diver's ability and to identify any deficiencies in skill levels. The last four (4) dives are to be TriOx dives at depth for experience, but not in excess of course depth limitations.

Academic Topics

Equipment Requirements

1.     Tanks/Cylinders: Students may use dual tanks/cylinders connected with a dual outlet isolator manifold, which     allows for the use of two first stages. Students may also use a single tank/cylinder with valve. All dives must start with a minimum of 80 cubic feet/2250 liters.

2.     Regulators: One of the second stages must be on a 5-foot to 7-foot/1.5-meter to 2-meter hose. One of the first stages must supply a pressure gauge and provide inflation for a dry suit (where applicable)

3.     Back plate System: A rigid and flat platform, of metal construction with minimal padding, held to a diver by one continuous piece of nylon webbing.

4.     Buoyancy Compensation Device: A diver's buoyancy compensation device should be back-mounted and minimalist in nature.  

5.     Decompression tables.

6.     At least one depth-measuring device.

7.     At least one timekeeping device.

8.     Mask and fins: Mask should be low volume; fins should rigid, non-split.

9.     At least one cutting device.

10.   Wet Notes.

11.   One spool, with 100 feet/30 meters of line per diver.

12.   One surface marker.

13.   Two lights; one primary and one secondary.

13.   Exposure suit appropriate for the duration of exposure.

Note: Prior to the commencement of class, students should consult with a Living Seas representative to verify equipment requirements. It is better for the student to learn while using his or her own equipment but we do have rental sets available upon request.
