I had two great dives with Big Blue, a wreck (Konanda) and the Twin Bommies. We were with 8 divers plus 2 Big Blue Master divers. The only thing I would suggest to this outfit is that they should provide at least 240 BAR of air, NOT 160 like I got (discovered on the boat to the dives, so it was either put up or don't dive!). On the twin bommies I got down to 45 metres and when I indicated that I had 100 BAR left (as I was taught during my 2 dive courses), I was waved on and told not to worry. So I concentrated on the beautiful environment and suddenly, at 45m, I found myself with only 20 BAR left. Result: I had to ascend must quicker than I should have, resulting in blood in the ear and thoat. The rest though was great! Just give us a bit more air, Big Blue!
