KEY LARGO, Fla.  —  A 22-year-old Marine, who lost his leg after combat injury in Iraq, used a special prosthesis Monday to scuba dive in the Florida Keys National Marine Sanctuary.

Jeremy Stengel of Waterford, Wisc., is part of a group of 14 soldiers with war-related injuries participating in Warrior Dive through Tuesday. The event is organized by the International Association for Handicapped Divers in conjunction with a Key Largo dive shop and other area businesses.

Stengel said the water leg prosthesis is more waterproof than the one he uses on land and features an artificial foot that can be extended so a dive fin can be used as normal.

"This was my first day really diving, seeing all the sea life." said Stengel. "It was amazing."

Stengel lost his leg in February 2007 while on a sweep for improvised explosive devices.
