Whats in the box:1st Stage, 2nd Stage LP Hose and Owner's Manual
Even with the best laid dive plans, there are times you encounter conditions beyond your control. The Delta 4.2 is one hot new 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 first stage regulator is a balanced diaphragm design which is environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.
Tthe 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 percent. 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 30" (76.2 cm) MaxFlex hose to further reduce jaw fatigue. Regulator comes with an Owner's Manual.
