How long should I wait to fly after diving?

Common agency and DAN-cited guidance runs at least 12–18 hours after a single no-stop dive and 18–24 hours or more after repetitive days — and your dive computer displays its own no-fly countdown, which is the number to obey. We are named for that window, not qualified to shorten it: follow your computer, your training agency, and DAN. Use the grounded time to rinse gear and read reviews.
