I stopped logging dives after I filled up my third log book. I just did not see any point in spending the money and I'm one of those people that does not read notes left to self Some one questioned me the other day on how I know the accuracy of how many dives I have really done. I suppose the answer to that is, I don't really care. I know what my skills are and being able to show someone a number on a page does not make me a better diver. I think it's great that people do log their dives if that is their thing. A friend of mine logs her dives religiously and we have fun going over the details that she records but that is about the extent of it for me.
