Scuba G Pool is a private salt-water practice pool in Petaling Jaya used for scuba review courses, self-practice, and mermaid training by appointment. The pool is compact and controlled, so it is best for skill refreshers and calm-water drills rather than open-water diving. It suits beginners and instructors who want a predictable place to rehearse buoyancy, breathing, and equipment checks. Because it is a managed pool, wildlife is absent and conditions stay stable.
