The Harasib is a huge Cave In Namibia, in the middle of nowhere far away from the next town. To dive there means, you have to bring the whole diving gear 80 meters down with ropes and after the dive back up again.
so it took uns 4,5 days to do just the one dive, which leads us 179 meters deep and took 7-8 hours. it was the deepest dive which was made in this cave. this is a short trailer, i will finish a longer movie in winter. - enjoy the trailer.
