Top Dive did a great job. Equipment was good although as previously mentioned we were surprised with Nitrox only. My wife and I have only 30 dives. We did not notice any changes using Nitrox. North dive was great and a bit easier for us. Dive masters were excellent We found the current in the south pass was stronger than we were used to. Extra effort in the south caused us to use air and shorten the dive. Might want to skip the south pass if you are inexperienced or not in the best physical shape. Also we stayed at Raimiti in the south end of the island. People that transferred from the north to dive the south and return the same day said it was a very long and tiring day.
