Chopper 5 flew over the boat Shear Water just after 11:30 a.m. and spotted medical personnel assisting two people off the boat.
The victims' names have not been released.
"I saw crime scene a couple of undercover cars and marine units. And then a couple of Coast Guard boats came here," said a worker who was in the area.
The boat belongs to dive expert Jim Abernethy who operates Scuba-Adventures.com.
The vessel was about a mile offshore at the dive site known as The Corridor, according to Abernethy.
About 15 minutes into the dive a man signaled he was having trouble and wanted to surface. Abernethy said he was found on the bottom unresponsive.
Two other divers rushed the man, described as being in his 50s, to the surface. The captain performed CPR, according to Abernethy.
"We were at the fuel dock and the Coast Guard came rolling in and went over to the dock over there with a gentleman with CPR in progress. Later EMT's came to the end of the dock waiting for the the dive boat to come back," said Nathan White, a visitor.
Because they surfaced quickly and could have been susceptible to the bends, the two divers who pulled the man from the water were taken to St. Mary's Medical Center as a precaution.
The victim was not local but had family members from the area on the boat.
