Intro Scuba Diving School operated in Daegu, South Korea, teaching PADI-standard recreational courses. The business has since rebranded and continues operating under the name "Daegu Scuba Diving SEA&I", now affiliated with SSI. Its long-running community hub (originally set up under the "introscuba" handle) remains active, with several hundred members and recent posts covering SSI Open Water Diver courses and technical equipment such as full-face masks and rebreather diving. As Daegu is an inland city, the school's diving activity is run out of town at coastal and inland dive sites rather than on a local shoreline; course bookings and scheduling are handled directly through the instructor.
