Not sure why you think you’d need to unscrew things to swap tanks. It’s the same as a jacket bcd. Your statement might be true for the regs..but they’re simple regs to work on and you can order kits from DGX. Ask your dive shop. I honestly don’t care. That initial package just seemed expensive for what it is and I hate those big console things.
I’m going to take a guess. As a new diver who has never seen a bp/w, he is seeing a picture of 3 different parts that need to be, somehow, attached to a tank. There is not a picture of an assembled bp/w on the linked page, so he’s not seeing the end result.I don't follow the unscrewing part either. There is no difference in swapping cylinders between a jacket style BCD and a BP/W.
@Elduderino
Would you explain what you mean?
Also, unless you have a good LDS, you may have to mail your regs to get them serviced properly. I had 3 different LDSs screw up servicing my regs so in the mail they went after I was fed up and prior to servicing my own regs.
