Author Divers Alert Network (DAN)
On his first-ever night dive, Sam, an uncertified and inexperienced diver with fewer than 15 lifetime dives, descended to catch lobsters with two other uncertified divers (Dave and Tim). The three descended, while a fourth diver (Ron) planned to freedive and assist with hauling in the anticipated lobster catch. A fifth diver (Eric) remained on the boat. (Note: All names are fictitious.)
The diver was a 19-year-old woman in good physical condition. She denied any history of medical problems and did not take any medications regularly. She completed her confined-water training several weeks before with no problems and was now doing her open-water training dives.
