The thing about Coz is it is quite variable. Some days is drift with little real work but just maneuvering position. Other days it's little current and gently efficiently finning from reef to reef. Other days it is swim throughs and tight little caves where control and staying off the walls and the overhead is the challenge. Most days it is all of that. I have been enjoying my RK3s but my experience is limited. I have done 12 dives here since Saturday. I love it.
