My family and I returned from A.C. on June 23. We did three days of diving with Ecologic Divers. They have a great shop. We usually had 6 or less divers but on one day there were about 13-14 so they took 3 divemasters out so each one only had 4-5 divers. They were safety conscious, took good care of their rental equipment, provided hot towels on the boat after the dive, and the divemasters took photos of the divers and marine life during the dives. When you were through, they would put the photos on a CD, at no cost. They also picked up divers from piers at or near the hotels/condos on the island. I would highly recommend Ecologic Divers. We will use them again on our next trip.
