During your advanced open water course you have to do 5 dives. Two dives are mandatory, these are: the Deep dive and the Navigation dive. The other three you can decide by yourself. One of these dives can be the diver propulsion vehicle also known as “DPV”. Here you learn how to handle the DPV and what are the hidden dangers in using it. Once in the water it will be a lot of fun. Most times the driver doesn’t notice what’s surrounding him coral and fishwife, because he was playing with the “DPV”. If you don’t have time to do the complete advanced open water diver course, then you can also try to do the adventure diver course.
