Advanced open water diver (AOWD) course is all about what you can do under water. You will not be removing your mask under water but rather you can work on your buoyancy, check some wrecks out or take some photos.
You can choose 5 dive/theory combinations from various themes in the areas of your interest.
After this course your diving area will expand, since will be certified to a maximum depth of 30 meters and allowed to do cool things, such as night diving.
You have to be an Open water diver or equivalent to attend. The mandatory dives on this course are UW navigation and deep dive to 30 meters, the rest you can choose from various themes. One popular combination is to deepen the understanding of diving theory in practice with a computer/multilevel dive, then bring out the nature loving artist that resides in all of us by doing a combination of UW photo and fish identification dives for which our dive sites are virtually made for.
