The Apeks XTX50 Stage 3 Regulator Set includes the XTX50 DST regulator and XTX50 Octopus for a complete high performance and cold water rated regulator set.

The DST first stage uses an over-balanced diaphragm design, is environmentally sealed and it is fitted with two high pressure, and four low pressure ports, which are placed in angles that support optimised hose routing.

The XTX50 is a pneumatically balanced second stage that offers great breathing performance. With diver adjustable inhalation and venturi air control  and anti-bacterial mouthpiece, the second stage is full of well-thought out features. Additionally, the second stage is reversible from right to left handed operation by a trained technician.

The XTX50 Octopus has all the same features of the standard second stage but it fitted with high visibility yellow hose, front cover and trim for easier identification,
