Explorer Monty Halls ventures into the unknown to uncover the secrets of the deep every Monday from November 25, Channel 5 at 9pm.
This week, Monty Halls and his team travel to Egypt to investigate why so many divers have lost their lives to the deadly beauty of the Blue Hole, said to be the most dangerous dive site on earth. The Blue Hole is situated on the Red Sea coast, a few kilometres north of the Egyptian resort of Dahab. 'It is thought to have claimed over 100 lives. There is something that is killing healthy, active, fit young men,' says Monty of the abyss that reaches a depth of 330 feet.
