Frank's Underwater Sports Pool is a heated indoor freshwater training pool in Edmond built for scuba instruction, buoyancy work, and skills refreshers. The shallow practice area supports first-time dives and class sessions, while the sloping pool gives instructors room to move students toward the deeper end for trim, control, and specialty practice. It is a controlled training venue rather than a recreational wildlife site, so the value is in predictable water, small classes, and structured coaching.
