The XTX200 with XTX40 octopus regulator set incorporates the top of the line XTX200 second stage combined with a very reliable XTX40 octopus. The FSR first stage is a high performance diaphragm design with environmental seal for improved cold water performance and reliability. This balanced first stage provides four low pressure ports and two high pressure ports at pre-orientated angles for optimal hose routing. The XTX 200 second stage provides all the features that you would expect from a high specification regulator including a balanced down stream valve for performance, customisable inhalation resistance, Venturi air flow control, and diaphragm deflector to prevent strong currents causing the valve to flutter. The XTX additionally has a reversible design allowing a trained technician to swap the hose handing and interchangeable exhaust deflectors which are switchable between a compact deflector or a wide deflector. The XTX40 uses the same basic components without some of the extras to reduce the overall cost. The second stage still features a Venturi control, diaphragm deflector, and reversible housing.
