I have been diving since I was 16 years old and continue to enjoy the science, sport, the creatures ... recording such on video and with photos as a 54 year old retiree. My husband and I are both Master Divers who, needless to say ... have much dive experience. However, we found this tool very sobering as we tested our memories and retained training. This tool is a truly useful refresher for anyone who continues to learn to be a better Diver ... A good diver is always learning.
