The Apeks Flight regulator was released in 2009 and is the lightest regulator in the world designed for travelling divers in waters down to 10 degrees. The Flight second stage uses a lightweight and compact housing making it ideal for travelling but the small size doesn't mean a lack of performance or features.
The second stage is fitted with a pneumatically balanced valve for excellent gas flows that is consist regardless of depth or cylinder pressure. The diver has control over the gas flow within the housing by operating the venturi lever on the side, delivering gas directly to the mouthpiece or diverting it back towards to the diaphragm which helps to reduce the risk of freeflows when entering the water.
This is the second stage only and is not supplied with a low pressure regulator (click here) and should be used with matching performance 1st stage.
