Whats in the box:1'st and 2'nd Stage Regulators, LP Hose and Owner's Manual
Even with the best laid dive plans, there are times you encounter conditions beyond your control. The Delta 4.1 is one hot regulator ready to take on all challengers with a new stylish look and FDX-10 First Stage featuring DVT (Dry Valve Technology). The FDX10 offers a balanced diaphragm and is made of forged chromed marine brass. It features DVT (Dry Valve Technology), an innovative design that keeps moisture and contaminants out of the first stage, even if you forget to put the dust cap on. This means internal components remain corrosion and bacteria free. 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). 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.
As is the Delta 4.1 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 4.1 is the latest version of the Delta, and 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 4.1 has Oceanic's patented Dynamic Adjustment feature. This lets a diver set breathing resistance. The adjustment only needs to be made once; the Delta 4.1 maintains the setting no matter the depth of the dive.
The Delta 4.1's ABS/Polycarbonate housing and anodized aluminum cover ring are exceptionally tough. The Delta 4.1 has an orthodontic mouthpiece that produces minimal jaw fatigue no matter the length of the dive.
