A pool option is listed at 800,000 VND. These advertised examples were read on 20 October 2026; they distinguish products rather than establish a universal Phú Quốc rate.
Compare instruction, preparation, equipment and the whole boat day before comparing cost per dive. One short experience sold during another excursion is not automatically equivalent to a programme built around learning. If the aim is to decide whether you enjoy scuba, a calm start with time for practice may be the most valuable part of the booking.
A certificate course needs its own quotation and calendar. Check which learning material, practical sessions and certification costs the course covers rather than carrying a try-dive price across to a different product. The point is to choose the learning outcome, not to purchase the longest underwater photo session.
