That went well - I survived. Because everybody wanted to get home and watch Germany beat Brazil (or so they thought), we did only the deep dive sunday. The search and rescue dive has been postponed until wednesday. Unfortunately the deep dive took a little longer time than expected so we did not finish before the match was practically over and Germany had lost. U/W navigation was interesting and nice to learn. Photography - well, now I've tried it :-) Saturday evening, after navigation and photography, we drove to another lake, waited until it got dark, and did 40 minutes of night dive. Even with powerfull flashlamps the visibility is very limited. Got home at 2, sunday morning. Sunday at 9:45 we went again, this time for the deep dive. Approximately 100 meters out and 20 meters down. 7 C temperature and 50 centimeter visibility. Nice.
