Course Content
The GUE Recreational TriOx course is normally conducted over a 3-day period, and cumulatively involves a minimum of thirty (30) hours of instruction designed to provide a working knowledge of Nitrox and TriOx, including history of decompression and practice, physics, physiology, tables, and operational considerations.
Course requirements include nine (9) hours of academics and six (6) dives, four (4) of which will be critical skill dives and two (2) will be experience dives as defined in GUE Standards and Procedures.
The initial two (2) dives will be conducted in water no deeper then 40 feet (15 meters) to evaluate the diver's ability and to identify any skill deficiencies. The last two (2) dives are to be TriOx dives at depth for experience, but not in excess of course depth limitations.

5. Valve failure procedures
6. Use of safety spools and lift bag
7. Basic navigation skills
Required Dive Skills & Drills
1. All skills and drills as outlined in General Diving Skills, Section 1.5.2. Demonstrate proficiency in procedures for gas failures, including valve manipulation and gas-sharing.
3. Demonstrate proficiency in lift bag/surface marker buoy deployment.
4. Demonstrate good buoyancy and trim.
5. Be able to comfortably demonstrate at least two propulsion techniques appropriate for delicate and/or silty environments.
6. Demonstrate proficiency in the use of touch contact communication during out-of-gas situations.
7. Demonstrate familiarity with required course equipment.
8. Gas-sharing scenarios to include a gas-sharing horizontal swim for at least 200 feet/60 meters.
9. Gas-sharing scenarios to include a direct ascent while managing decompression obligations.
10. Demonstrate effective buoyancy control.
11. Demonstrate effective valve-management by first going to a team member for OOG and then shutting down a valve and returning it to the open position again.
12. Demonstrate effective proficiency with proper ascent/descents, including the implementation of deep stops.
Equipment Requirements
Each student should have, and be familiar with, all of the following required equipment.1. Tanks/Cylinders: Students may use single or dual tanks/cylinders with a single outlet, Y-valve, or if in doubles a dual outlet isolated manifold, which allows the use of two first-stages. All dives must start with a minimum of 80 cubic feet/2250 liters of gas.
Regulators: Single first-stage if using a single tank with single outlet or two (2) first-stages if using either a single tank with Y-valve or double tanks. A minimum of two (2) second-stages. One of the second-stages must be on a 7-foot/2-meter hose. The diver must have a pressure gauge and BCD inflator.
2. Backplate System: A rigid and flat platform, of metal construction with minimal padding, held to a diver by one continuous piece of nylon webbing. This webbing should be adjustable through the plate and should use a buckle to secure the system at the waist. A crotch strap attached to the lower end of this platform and looped through the waistband would prevent the system from riding up a diver's back. A knife should be secured to the waist on the left webbing tab. This webbing should support five D-rings; the first should be placed at the left hip, the second should be placed in line with a diver's right collarbone, the third should be placed in line with the diver's left collarbone, the fourth and fifth should be affixed to the crotch strap to use while scootering or towing/stowing gear. The harness below the diver's arms should have small restrictive bands to allow for the placement of reserve light powered by three in-line c-cell batteries (where necessary). The system should retain a minimalist approach with no unnecessary components.
3. Buoyancy Compensation Device: A diver's buoyancy compensation device should be back-mounted and minimalist in nature. It should come free of extraneous strings, tabs, or other material. There should be no restrictive bands or "bungee" of any sort affixed to the buoyancy cell. In addition, diver lift should not exceed 50lbs for a single tank and 80lbs for double tanks. Wing size and shape should be appropriate to the cylinder size(s) employed for training.
4. At least one depth-measuring device
5. Compass
6. One timekeeping device
7. Minimum and No-Decompression Buhlman based tables
8. Mask and fins: Mask should be low volume; fins should be rigid, non-split
9. Minimum of one cutting device
10. Wet Notes
11. One spool with 100 feet/30 meters line per diver
12. Exposure suit appropriate for the duration of exposure
13. At least one surface marker buoy per diver
14. Divers utilizing a dry suit must have a separate (from the back gas) dry suit inflation source such as an argon/air bottle. Divers may not inflate the dry suit from the back gas.
