About Oceanic Delta 4.2 FDX10 Yoke Regulator, Black with Swivel

Even with the best laid dive plans, there are times you encounter conditions beyond your control. The Delta 4.2 is one hot regulator ready to take on all challengers with a new stylish look. The FDX10 offers a balanced diaphragm and is made of forged chromed marine brass. At 28 oz (794 g), the FDX10 is one of Oceanic's lightest weight first stages. Two high pressure and four low pressure ports assure a place for all your necessities and accessories.

The FDX10 offers a balanced diaphragm design nitrox ready out of the box up to 40%. The balanced diaphragm, first stage regulator is inherently environmentally sealed. Water enters the main spring cavity and the pressure increase from the water is transmitted to the internal components by the impermeable diaphragm membrane. The benefit of this type of first stage design is that none of the delicate internal parts are exposed-to-contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants can cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. A diaphragm first stage regulator requires less-maintenance then regulators that allow these contaminates to enter the internal mechanism. In addition the FDX10 First Stage Regulator has a secondary diaphragm to completely seal-off the main spring cavity. A sealed balanced diaphragm design; Enviro Kit and patented DRT (Dry Regulator Technology) isolate the main spring cavities internal components from the environment. It also means the FDX10 is excellent for ice diving (it won't freeze up) or diving in waters filled with contaminants or sediment (it won't corrode).

As is, the Delta 4.2 second stage, weighing 6.8 oz (192.78 g) it comes ready to use with air or nitrox mixtures up to 40%. The Delta 4.2 the latest version of the Delta is one of Oceanic second stages with (AVS) the Adjustable Venturi System. This allows the diver to adjust inhalation effort so the second stage won't free-flow during shore entries or long surface swims. Additionally, the Delta 4.2 has Oceanic's patented Dynamic Adjustment feature. This lets a diver set breathing resistance. The adjustment only needs to be made once; the Delta 4.2 maintains the setting no matter the depth of the dive.

The Delta 4.2's ABS/Polycarbonate housing and anodized aluminum cover ring are exceptionally tough. The Delta 4.2 has an orthodontic mouthpiece that produces minimal jaw fatigue no matter the length of the dive. Regulator is equipped with an inline ball swivel and a MaxFlex hose to further reduce jaw fatigue. Regulator comes with an owner's manual and is covered by a 24 month limited warranty.
