I can't speak for Calidivergirl, but I can speak from my experience that if you dived the passes everyday for a month and thought they were the same dive, you're doing it wrong, or more likely you're diving with the wrong dive operator. The Tiputa pass on Rangiroa alone is dived a dozen different ways all depending on conditions, which way the water is flowing, if there was rain recently, what you want to see etc... You might dive close to the shore to experience mantas, you might dive the canyon and grab a rock and sit there the whole dive to watch, you might dive the middle of the pass deep to see great hammer heads or tiger sharks, you might zoom the pass, you might change dive plans in the middle of the dive because dolphins have shown up... the list goes on and on. This is why I'm so highly discriminatory when choosing a dive operation, I want to dive with operators who love diving and want to show you their secret world, not some dive op simply churning the numbers day after day.
