This webbing should be adjustable through the plate with triglides to hold positions, and a buckle to secure the system at the waist.

A knife sheath should be attached at the waist and will be adjusted beside the crotch strap when ready. This webbing should support five D-rings; 1 on the left, and 1 on right shoulder strap, both approximately the collar bone level. 2 on the crotch strap with one at the front and one at the buttocks. The shoulder straps should have small rubber bands to hold the back-up lights. The system should have no unnecessary components.



• Buoyancy Compensator Device: The buoyancy compensator device should be back-mounted and streamlined with only one inflator. There should be no bungee cords of any sort on the buoyancy cell.

• One spool of at least 50 meters of line per diver.
• One primary reel of at least 120 meters of line per team.
• One exposure suit that is appropriate for the training environment and water temperature.
