The TDS Gull Z is an improved, lighter version of its successful predecessor, the Gull Tek second stage, with an improved lid and a heat exchanger that improves performance, especially in cold water.

The Gull Z is a reversible second stage, which allows the assembly to the hose from the first stage, either by the left or right.
This feature makes it perfect for use in lateral configuration, or sidemount, where one of the second stages, needs to be fed from the opposite direction.
