I have to just post how proud I am of my wife and 12 year old son who just passed there confined water checkouts and written exams last week. I thought they were both going to have aneurisms try to do practice problems for planning multiple dives using the tables (I had forgotten how confusing the table can be at first ) but they both passed with flying colors... OW dives a beaver when it warms up a little and they'll be all set!
