Diving In Singapore
The cheapest place to finish the course would be taking a day-trip to Singapore's backyard, where diving sites can be visited without a passport.
But diving spots around Singapore have strong tidal currents. These undercurrents are not dangerous if you know what you are doing. If it is your first dive, however, there will be potential hazards.
Singapore's murky water is even worse. It is necessary to have enough visibility so that you can clearly see what your instructor does underwater. And it is also vital for your instructor to catch you doing your drills wrongly, and then correct your mistakes. If your mistakes are not corrected, you will be getting a diving license to kill yourself in the future.
