The Apeks XTX 50 Second Stage is a compact second stage that comes with an inlet heat exchanger, and a full metal valve barrel for improved cold transfer efficiency. A Venturi lever allows customised control over the airflow within the housing. An inhalation control knob allows the diver to increase the breathing effort required to open the valve if required.

Divers who dive with a backup regulator hung on their neck, and want it in Black will also like this product. The Apeks XTX 50 Second Stage is capable of handling most brands of 1st stages in the market. This item does not come with an interchangeable exhaust.
