Not an atomic expert, but I don't think you can order Z2 with swivel turret straight from atomic. It is a option in a sense that you can purchase the turret separately and have the that installed, either by a dive shop or by atomic. So the additional cost is the cost of the turret.
But I wonder why swivel turret is any useful for single tank back mount. Maybe for side mount for double back mount?
Actually you can. We ordered them that way. Seems like at the time it cost us $50 more but that was a 10 years ago. As for the turret being useful over the fixed ports. I like it because the fixed ports are not always in line like one would want them. That is because of how the threads are cut. Which differ from reg to reg.
