I first dived the Red Sea just after Moses and the Israelites had crossed it. No, that’s an exaggeration but now it does seem like a very long time ago.
Scuba-diving was in its infancy and most of the experienced dive-guides had learnt their business from being backpackers who had a go at diving. They did a lot of diving and had a tremendous amount of experience together with masses of in-water confidence, yet their theoretical knowledge of diving could be a little sparse.
The calm clear deep water invited the intrepid to go deep. There soon grew up among dive-guides a deep-diving culture that was to claim many lives. The Blue Hole at Dahab regularly claimed divers and, in those days, military ‘helium-divers’ from the Israeli were called in to recover the bodies.
