I re -read my manuals while i was doing my DM course, and a recent discussion about casualty lifting got me re-reading my Rescue diver manuals. I seem to have inadvertently booked myself onto an IDC/IE in September so I really should get them all out and read them all again. Add in my, newly aquired ,TDI manuals, a couple of Dive physiology books that I found in my local library and innumerable diving websites and fora and its a wonder that i have any time for the actual diving!
