If it were possible to give this organization zero stars, I would give it zero.We visited this dive center twice, for diving and excursion. The diving went perfectly, for which many thanks to our instructor Sergei. From the first minutes it was clear that we were in the hands of professionals, and therefore the first diving experience turned out to be as comfortable, safe and interesting as possible.Unfortunately, returning to this center for a tour canceled out all the positive emotions from the past experience. It would be better to go diving again than to have this misunderstanding. Organizing the excursion is a complete failure. For 22 participants there was only one instructor, Alexander. Whether one instructor can ensure safety and order in such a large group is an open question. In parallel with our group, there was another mini-group in the boat with its own separate instructor.The first point of the excursion was the manta rays. I had a dream - to swim with manta rays, and due to organizational problems this dream did not come true. At this point, already in the water, it turned out that the snorkeling mask issued by the organizers was defective: its attachment for the snorkel was broken, so the snorkel fell off and floated away every two minutes. Most of the time, instead of searching for manta rays, was spent catching the tube and trying to fix it in place; in the end, the tube was taken away by a wave and carried to the bottom. I swam up to the instructor and asked if there was a spare mask, because my snorkel had sunk. “Bad. Fine 20 dollars,” said the instructor and sailed off into the sunset (literally sailed away without offering at least some solution to the problem). This was the first time I encountered such a disregard for the organizers. At the very end of my stay at this location, I borrowed someone else’s mask, but I never saw the manta rays... And I wouldn’t have seen everything else if not for a girl from the excursion participants who, returning to the boat, found a lost tube at the bottom, dived and returned it to me. Only thanks to this girl I was able to swim at least a little at the second point (still constantly catching the snorkel) and not end up paying $20 for an initially defective mask))If at the first point the participants managed to somehow disperse, then at the second, with the sharks, it was a complete mess. Due to the large number of participants in a small space, it was constantly being hit on the head by someone’s flipper or someone’s elbow.The third point, with a sand spit - no questions, everything was clear, the food was delicious with sandwiches with french fries and watermelon.And only at the last, fourth point, Alexander reluctantly said, “Well, let’s see what you have there,” became convinced that the fastening of my mask was really faulty, and moved the tube holder from his mask to mine. Only at this location I was able to fully snorkel.To summarize: I categorically recommend diving from this company and categorically do not recommend excursions.
