I'm in the water so much I don't have time to log every dive if I make. I have probably made 40 dives in the past month or so.
No offense man but I've made about 40 dives in the past month and that is precisely why I'm still logging every dive. It's nice to have a reference on what exposure suit, cylinder, weight, etc I was wearing. I also keep notes on who I've dove with, who I'll dive with again and who I'll try to avoid or be more careful with. Not every entry is real detailed, alot say "crabbing" or "dove 2" but I get the weight, gear, tank info and psi going and coming for sac calculations. I keep critical notes on my own mistakes as well.
I log pool dives if I'm getting an orientation/training in something new and get the dm/inst to sign, but I don't count them toward my "logged dives".
I know old timers that say "Ah I'd have 5000+ logged dives if I kept a log book," and I know old timers that have 5000+ Logged Dives.
