The following is a video shot while scooter free diving along much of the length of the newly sunk Vandenberg Artificial Reef. It was placed about 7 miles south of Key West in 140 ft. of water. It landed on even keel and provides a pretty amazing dive in the often clear blue waters of the Florida Current. Viz. was limited at about 50 to 60 ft. during the dive and there was a strong current running north. Still some interesting images came out of the dive. The video was shot with a Canon G9 digital camera in their housing with stills being shot every 2 seconds with a Go Pro 170 degree field of view camera in a chest harness. CLICK FOR VIDEO
