Cave Diving gone wrong - true horror story. This is a story about the outcome of a diver who went beyond his training and experience which lead to tragic, deadly consequences. Dillon also loved diving. For Christmas 2013, Darren had gotten Dillon new gas tanks, and the pair couldn’t wait to try them out. That same day, the pair headed to Burford Spring but it was flooded so they went over to Eagle Nest, a particularly dangerous undersea cave system in northwestern Hernando County in Florida. Eagle's Nest is a technically challenging and risky cave dive. Only highly skilled and certified experts should consider or attempt it. It's easy to become lost, and there's no "safe zone" where you can regain your bearings. Since 1981, up to 20 people have died in the Eagle's Nest cave system. Spivey was a certified diver, but he didn't have a cave diving qualification. He should have never attempted the dive, let alone with his unexperienced son.
