Besides the regular open water diving, there are two other kinds of scuba diving that you can enjoy in the Andaman Islands.
Yes, this means diving at night! It makes the activity more thrilling and adventurous and you can see many nocturnal animals such as polyps that withdrawn into their skeletons during the day, and protrude out for feeding at night. In the dark, you dive with a powerful scuba torch that helps you see and communicate with the other divers. You will also be taught some basic scuba sign language that you will use with the torch illuminating your hands.
Diving deeper into the sea is ideal for exploring coral reefs and wrecks. Deep diving takes you till 30 metres under water, and can be dangerous if not organised properly. Ask a lot of questions and make sure everything is in order before attempting this one. Once you get there, however, you'll be able to see rare species of marine life that are usually not visible above.
The price depends on what you want and which diving school you pick. The cost includes the rent of diving gear and underwater photography and video. To give you an estimate, here are some approximate costs:
A single dive – Rs 4500 to 5000 (This includes an introductory scuba session, and one guided dive with an instructor.)
Two dives – Rs 6000 to 7000
Scuba lite – Rs 3500 (This includes a shorter version of the introductory scuba session and your time underwater is limited to 30 minutes.)
