Aqualung Calypso Classic Second Stage is a mid-sized, high performance, reliable, demand valve second stage.
Venturi knob stops unwanted freeflow when the regulator is out of mouth and it comes with the Comfo-bite -mouthpiece which is designed to reduce jaw fatigue.
This all time favourite is easy to purge, creates finer bubbles for better visibility and stability. It is of strong make and great value for money.
