Hi guys. I recently got in the market for a dive knife for an upcoming PADI advanced class. Ideally I would like to have the knife be attached to my BCD, the Aqualung Dimension. It has grommets on the left side. The spacing between the two holes is 4 inches center to center and each hole has a 1/4 inch diameter. Does anyone else have the same BCD or one with the same spacing and have a good dive knife that fits it? I know the aqualung dive knives are of the correct spacing but they seem to be overpriced compared to others. Worst comes to worst I'll probably use zip ties but hopefully not.
