This was yet another great experience for me. I saw a deck and a boat that were sunk in Blue Lagoon #1. They were both about 30 ft down and 10 - 15 min dives. After I came up from both dives I coughed up some blood, but felt fine. Later I found that it`s common and I needed to take more time to adjust to the pressure changes. SCUBA knowledge: INCREASED!!
