Definitely. I recommend that one stick very close to his/her buddy as popular dive spots can get very crowded, one can easily be lost and end up on the wrong boat on return!

An underwater light source, make that 2 for safely reasons, is mandatory to avoid destroying any aquatic life or injuring oneself (such as swimming straight into a reef overhang).
