37Currents are to be expected at some of the most exiting diving locations in the world. This includes rivers with walls that have been polished by centuries of water flow. This also includes locations where big plankton eaters (such as manta-rays and whale-sharks) may be seen as well as some of the most exciting reefs in the world. The ability to deal with currents gives access to some extremely exciting diving opportunities.

Currents come in an enormous variety. Currents in a river require completely different techniques than diving in currents on a reef in the ocean. And then – 4 different rivers can require four completely different sets of procedures. The same goes for currents in the ocean. This means that there is no “standardised” theory session or book for this course. The idea is to learn from the instructor who has ample experience with the condition in the region where you are going to be diving.

Diving in currents requires a minimum age of 10. As ropes are used frequently in currents, there will be a session on land to tie knots. The number of dives for this course is two.

Your instructor will want a completed medical statement from you. In some regions a medical statement with only “no” answers will be sufficient for participation in the course. In other regions a medical signed and stamped by a medical doctor will be required and must unconditionally say that you are fit for diving.
