Diamond Reef System, including each individual Hover Station and the new Multi-Portal System, are trademarked, skill evaluation and safety-based diving curriculums that utilize the world's first portable, collapsible underwater obstacle course to simulate fragile reef or dive wreck structure for diver buoyancy skill and underwater photography training.[1][2] A form of scuba Gymkhana, the program was designed by Pete Wallingford in 1988 to educate scuba instructors and scuba divers on how to safely teach and promote situational awareness, proper body positioning and safe interaction with coral reefs, fragile marine ecosystems and shipwrecks.[3] The program was adopted by the Environmental Protection Agency, the National Oceanic and Atmospheric Administration,[4] dive store operators and dive resort/charter operators worldwide.
