About Oceanic Delta 4.2 FDX10 Regulator, Black with Swivel

The FDX10 offers a balanced diaphragm and is made of forged chromed marine brass. The balanced diaphragm, first stage regulator is inherently environmentally sealed. 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 contaminates to enter the internal mechanism.

The FDX10 features DVT (Dry Valve Technology). DVT takes keeping the internal components clean of contaminates to the next-level. DVT is an innovative design that keeps moisture and contaminants out-of-the-first stage, even if you forget to put the dust cap on. Have you ever wonder why they call it a "dust cap" and not a water cap. DVT eliminates the possibility of moisture entering the first stage with a simple, yet ingenious design. No hassle, no worries. What about performance? DVT doesn't impact first stage performance even at 198' (60 meters) with just 200 psi (14 bars) in your tank. The result is an end to flooded regulators! Oceanic's exclusive DVT is designed to automatically eliminate moisture intrusion and contaminants from entering your breathing system. This means internal components remain corrosion and bacteria free. Amazing, simple, patented, and by the way, DVT is only available on Oceanic Regulators.

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). The FDX10 DIN first stage comes ready to use with air or Nitrox mixtures up to 40%. First stage has 4 low pressure (LP) and 2 high pressure (HP) ports. FDX-10 features optimized air paths and angled hose ports for superior performance and comfort.

The Delta 4.2 is a mechanically balanced second stage, it comes ready to use with air or NITROX mixtures up to 40%. The Delta 4.2 is the latest version of the Delta, and is one of Oceanic second stages with (A.V.S.) 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. The A.V.S. deflector vane found in the Delta 4.2 diverts the airflow from the valve directly to the mouthpiece, producing smooth venturi-assisted inhalation. With the addition of a user Adjustable Venturi System (A.V.S.), in the form of a simple yet ingenious switch, full adjustment control rests in the hands of the diver. 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.

A common objection to adjustable second stages is that divers can't imagine themselves twisting and turning a knob as they descend and ascend through the depths. If inhalation resistance is set near zero at depth, your ascent would require you too manually increase resistance as ambient water pressure is reduced to prevent free-flow. Taking another stride beyond common second stage engineering, Oceanic designed a patented dynamic adjustment feature into the heart of the Delta 4.2. This mechanically balanced valve maintains a preferred breathing resistance throughout the dive. Set it once and the Delta 4.2 automatically adjusts to make breathing as easy at 100' (30 meters) as it is at 30' (10 meters) - with no additional manual adjustment.

The Delta 4.2's housing is made from an ABS/Polycarbonate composite blend of materials making the Delta 4.2 both extremely rugged and lightweight and nearly neutrally buoyant underwater, reducing jaw fatigue on extended dives. The extremely lightweight cover ring is machined from a solid piece of aircraft aluminum, and then hard anodized, utilizing a unique process to prevent corrosion. Ever notice that nearly every picture you see of a diver, their regulator looks like it's not the least bit comfortable? The Delta 4.2 features an ergonomically designed in-line swivel for ultimate comfort. The Delta 4.2 takes this comfort even further with an orthodontic mouthpiece designed to accommodate the natural overbite of the human jaw and 30" (76.2cm) 3/8" threaded Maxflex hose that all produce minimal jaw fatigue no matter the length of the dive. Regulator weighs 34.8oz (986.8g) without the hose, comes with an owner's manual and is covered by a 24 month limited warranty.

The Oceanic Delta 4.2 FDX10 Regulator, Black with Swivel is commonly used for Warm Water and more. The Oceanic Delta 4.2 FDX10 Regulator, Black with Swivel is popular because customers like the following qualities of the Oceanic Delta 4.2 FDX10 Regulator, Black with Swivel: Adjustable, Comfortable, Effortless breathing.
