1. Tanks/Cylinders: Students are required to use dual tanks/cylinders connected with a dual outlet isolator manifold, which allows the use of two first-stages. All dives must start with a minimum of 80 cubic feet/2250 liters of gas. Divers must also have access to one deco tank/cylinder of 50% Nitrox.
2. Regulators: Two first-stages, each supplying a single second-stage. One of the second-stages must be on a 7-foot/2-meter hose. One of the first-stages must supply a pressure gauge and provide inflation for a dry suit (where applicable). One first-stage regulator for shallow decompression gas, supplying a single second-stage and pressure gauge.
3. 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.
4. 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 80lbs. Wing size and shape should be appropriate to the cylinder size(s) employed for training.
5. At least one depth-measuring device
6. One timekeeping device
7. Decompression tables
8. Mask and fins: Mask should be low volume; fins should be rigid, non-split
9. At least one cutting device
10. Wet Notes
11. One spool with 100 feet/30 meters line per diver
12. One primary reel per diver, with a minimum of 300 feet/90 meters of line
13. One primary light: A primary light should be minimalist in design; its power source should consist of a rechargeable battery pack residing in a canister powering an external light head via a light cord. Primary lights should produce the equivalent output of 50 watt halogen/10 watt HID lighting or greater.
14. One lights: Reserve lights should be non-rechargeable in-line three c-cell battery lights with a minimum of protrusions and a single attachment at its rear. The light should be activated by twisting the front bezel towards the body, deactivated by turning it away from the body.
15. Exposure suit appropriate for the duration of exposure
16. At least one surface marker buoy per dive
