Most beginner divers make the mistake of swimming too fast under water. In fact, fins are not meant for going fast. If you want to go fast, you should use an diver propulsion vehicle (DPV), also known as an underwater scooter. DPVs are a fun way to cover large areas under water, dive against strong currents, and improve air consumption by decreasing the effort of kicking. This course includes a theory module and two open water dives. Emphasis is placed on proper dive planning using a DPV, handling procedures, especially during descents and ascents, DPV maintainance, as well as dealing with potential problems.
