We had visiting in first week of this January, with my family of three members. Though as per their routine they provide training through video and Swimming pool on the first day in second half and arrange scuba diving next day in first half, in our case they arranged both the activities on same day,as we had very limited time and peoples were extremely cooperative.
Video was about 20 minutes, which demonstrated basic skills required for scuba diving. At the beginning, we had to fill the prescribed form, which had many clauses and declaration regarding sound health with details.
Main training was in Pool, after which all these skills were tested in the 25ft deep part of the same pool.
If a person is not comfortable in 25ft pool, they do not go for scuba diving in sea. Charges were 3500 +tax per person. On the top of it, they provided 10% discount, being more than 02 person in the group.
For reaching scuba diving point in the sea, 18 km travel by Speed boat is required, which is equally amazing experience and Full PAISA VASOOL.
After one hour thrilling journey, we reached at the point, where approx 1 hour activity was made, which was an unique experience. Water was clean and sea life was visible very clearly.
Guide cum trainer cum mentors were very helpful and caring.
This institute belongs to MTDC and there is stay arrangement also, which we availed. Room was good and rates were reasonable @ 3000 plus taxes.
With stay at this place, apart from doing scuba diving, we enjoyed Tarkarli Beach also, as it is situated at the beach only, away from crown.
Wonderful experience on each part.

Indian Institute of Scuba Diving & Aquatic Sports or IISDA is the only decent place with whom one should go SCUBA diving with. They are thorough professionals in approach. Costing is nearly 4-5 times the other ones available locally, however, the quality and safety of IISDA is unparalleled. We hade recently done SCUBA diving at Havelock islands in Andaman and this experience was almost on par with them. The divers are qualifies PADI SSI and the ratio is also 1:1 to each person. Theplace they took us for the actual dive is exclusively reserved only for IISDA and hence was pristine and not crowded. Saw a lot of fish, even though water is not that clear. The practice swimming pool is almost 2 floors deep on the terrace and was a good place to practice before the actual dive !!

Strongly recommended.

We went on last weekend for specially scuba diving, had amazing experience of inside water world. For scuba diving, you need take breathing inside of your body / outside of your body slowly slowly. Don't be panic inside of the water. Be clam and enjoy beautiful water world.
