Anyway -
I do both. Dove a D3 for quite awhile. Just moved to the Vytec. But I still schlep around a dive log. It looks like a sun worn, sea sprayed full-on 80's Franklin planner. It's fat, over stuffed with notes, and it goes everywhere with me.
For me, the narrative is as important as the dive - what I saw, what the day was like, what I was feeling on the dive, who I was with, etc. I write a lot of stuff in my Wetnotes during a dive as well (mostly to communicate with the buddies.... just as BWERB! :snooze: ) and all of this stuff goes into my log.
Its a cross between scrapbooking (I'm such a chick that I even know that word...

) and a dive log.
On a recent trip, I was the ONLY one with a log. I was pretty blown away. Where I'm from, we're all pretty anal about logging stuff.
Its one of my most treasured pieces of dive gear. Its tracked every dive so far - from OW training, to DIR/F, to all the drills and practice, to the travel...it tracks everything. My SAC, my weighting, my experiments in gear config (pre DIR) and has tables, charts, dials, a calculator, a couple of pencils and even some printed PM's from Scubaboard. I never dive without it.
