My first serious dive trip, nearly a quarter century ago, included a liveaboard trip to the GBR One of the divers on the trip was a Japanese professional marine photographer, a remarkably skilled diver. He had thousands of dives logged, and he took meticulous notes after each dive. I took him as a role model and have logged every dive, although not as meticulously.
At first I used the log book that came with the OW course.
Then I bought a loose leaf binder that came with printed pages. I used several refill packs for that. I briefly lost the binder and bought a second, smaller one, so I now have an old one for archives a new one for recent diving.
I tried the Suunto system and decided it wasn't worth it. I also saw the trap of technology--when the technology changed, that source was no longer available to me, so I put them on paper. You can always use paper.
I designed custom pages and printed them off. They were fine until I decided they were too much of a PITA, and I was wasting a full sheet of paper for a dive for which I had little to say.
For many years now I have used just plain sheets of paper. I cut full sheets down to size and punch holes. On some dives, I have next to nothing to say, and I can fit 3 such dives on a page. On other dives, I have written 2-3 pages.
