Edmonton Leisure Centre is a controlled indoor training pool in north London used for scuba sessions and beginner skills work. The setup is shallow, predictable, and instructor-led, with a movable floor that lets the pool depth be adjusted for drills and certification practice. It is an indoor training environment rather than a scenic open-water site, so the value here is comfort, repetition, and easy supervision. Divers use it for first sessions, refresher work, and pool-based training before heading outside.
