the only dive i recorded in a pool is Nemo33 (Bruxelles, Belgium) : 111 feet
This dive I would log. No doubt!
But I don't log pool dives. And to me, depth is irrelevent. If my dive hits 20 minutes, it gets logged. A dive bud worked on a motel pool in the middle of winter. Used a dry suit and he was paid. Dive under 15 mins. I would have logged that one since it was so unusual(for him).
If I were to dive a large aquarium(eg Georgia), I would log that dive since it was unusual.
It is personal preference.
