Identical to the XTX40 second stage but lacking the components to make it cold water compatible the XTX20 second stage is a high performance warm water regulator with many of the excellent XTX features. From the factory the XTX20 regulator is set up in a right hand configuration, this can be changed so that the hose and venturi system come from the left. This allows a diver to more comfortably route their hoses. The diver can also change the exhaust tee on the XTX20 second stage, opting for a small tee to make the regulator more compact or a large one to disperse their exhalation bubbles more effectively. As a balanced second stage the XTX20 gives a super smooth breath regardless of the demands placed upon it.
