Did not ask about ScubaBoard, I try not to talk too much on dive boats, just watch and listen, 2 were talking tech talk, you know ,gear, gas mixes, places and dives they had done etc etc, switch off, all the usual, 2 were Asians and had all the "toys", all Scubapro gear except the computers 1 Shearwater 1 with Scubapro G2 to match the gear. My buddy was the large dude with the pony cylinder,did not know him from bar of soap,told me how often he dives, cashed up and does double dives a couple of days a week [weather permitting], good diver, we left each other alone, arrived at the deco stop [call it a safety stop] at he same time, all good.
So 5 Shearwater and 1 Scubapro G2 , that's 6 out of 12 divers, all the others were the usual suspects that I could tell, could be more.
