Whats in the box:1st Stage, 2nd Stage, Braided Hose

The NEO is comprised of precision-machined components and extensive R&D with the goal of creating a lightweight, high performance regulator. Mission Accomplished. The NEO features effortless pneumatically balanced breathing paired with a compact over-balanced diaphragm first stage. The pneumatically balanced second stage reduces breathing resistance to near zero with a balanced valve seat designed to respond to the slightest inhalation. A pneumatically balanced second stage actually has (or can have) the same initial crack opening effort as a mechanically balanced, but the spring force of a pneumatically balanced second stage is lighter so it's spring rate is also lower. Therefore the force required to open the valve farther as flow increases is less than that required for amechanically balanced second stage with a higher rate spring. So the total effort to breathe the pneumatically balanced second stageis indeed less. The spring force must be just enough to overcome the difference between downstream air pressure and upstream balancechamber pressure. The downstream air travels through a hole in the poppet into the balance chamber and applies an "upstream" force just slightly less than the downstream force. Ergonomic A.V.S. (Adjustable Venturi System) Dive/Pre-Dive Switch designed to be unobtrusive, yet easily manipulated even with the thickest gloves, the A.V.S. deflector vane found in the NEO either diverts airflowfrom the valve to the mouthpiece, producing effortless ventu ri-assisted inhalation or creates enough resistance to prevent free flowon the surface. The NEO was designed using the latest 3-D computer modeling techniques. This allows us the ability to model and testperformance while still in the early stages of development. The NEO's unique valve, deflector vane and housing design direct airflowfrom the valve directly to the mouthpiece, producing nearly effortless venturi-assisted inhalation. The CDX5 first stage is made of chrome plated marine brass and has a balanced diaphragm. With this design water doesn't enter the first stage, which means the CDX5 is excellent for ice diving (it won't freeze up) or diving in waters filled with contaminants or sediment (it won't corrode). Weighing 29 ounces, the CDX5 is one of Oceanic's heaviest first stages. As is the GT3, it comes ready to use with air or nitrox mixtures up to 40 percent. Two high pressure and four low pressure ports assure a place for all your necessities and accessories.
