Before the XTX range of regulators came along, the ATX models ruled the seas. The ATX is still available today and offers a fully balanced first and second stage with cold water capability (can be used in all temperatures including those below 10 C / 50 F).
This high-performance regulator boasts an over-balanced first stage coupled with a pneumatically balanced second stage.
The smooth, quiet breath is sure to enhance your diving enjoyment.
Suitable for coldwater use thanks to its first stage environmental dry seal and second stage heat exchanger.
Compatible with EAN40 out of the box.
