If you go diving at night, determine beforehand what you want to see, how far you want to move and what you want to experience in the end.
Are among you divers who have never dived at night, make them clear that they should join you and can not go their own way.
Check your equipment beforehand, most of the lamps are good for illuminating the way, but only a few, which are also used for filming.
Since this disaster I handle it so that I choose an object in daylight and then visit it at night with my camera. I do not know the area, I leave the camera right at home. Because then I rely on a leader and can not force this my pace.
