To add more to this question ... This is something I am curious about. I'm ot sure if this question deserves its on thread.
I have been logging all my dives with details such as depth, time, location, buddy, charter info, divemaster name, the usual stuff, etc but I usually never have anybody sign my book unless I get the chance. Basically half of my dives are "logged" with lots of details but not signed off by a buddy or divemaster even know I could probably track down most of the people I dove with if I wanted to. My question is, if I plan on continuing my certifications to divemaster will they hold this against me? Can I still go for the divemaster or even an instructor if the dives in my log book aren't technically signed off on?
