I don't dive, but I can tell you the snorkelling is great in SAI, so I assume diving might be even better. I haven't stayed at the Marazul but I know there's a man there called Mario that organizes tours to many diving spots. Check the MSN Group Big Juice's San Andres (you can find it through Google) to get plenty of info.
I made a mistake. According to Big Juice's group, Mario does only arrange snorkelling tours. Check this page to get the info you need:
It is a great place to dive based on all of the reviews from past travellers. There are many dive shops on the island. Werner from Kabrik divers comes highly recommended by all who have used his services.
If you are staying at Decameron Marazul :
Get in touch with Mario...he has his boat at their dock.He takes shuttles out free. This is o.k. but what you want is his own excursion which he will take you on for 20.00...he & his wife will give you Snorkeling at it's very best !!
If it's DIVING you want,he can advise you about anything you may want.
