Its official, tomorrow i am diving the Blue Hole and doing the Archway. It is called "The worlds most dangerous dive" due to the huge number of people that died attempting it. That said, its not really a risky dive for a tech diver. The Archway is about 190 feet/ 60 meters down and provides a tunnel out to the open ocean. I'm going to try to record it.
@trinsec
Yup exactly. A pretty big dent but yes ;)
@freemo So it's almost underwater sort of spelunking you're going to do? Man, you gotta film that tunnel.
@freemo So that circle is a DENT with walls on all sides that goes down deep. Then there is a small HOLE at about 60-70 meters depth that connects it to the ocean? Just making sure I understand.
