This is a great reg and a great price especially when purchased with one of the packages. I love the Dry Valve Technology which makes it a lot easier to clean without worrying about water entering the first stage. Only complaint is the plastic on the reg seems a little cheap and I wonder how long it will last. Im at about 40 dives so far with no major problems though.

I have only used about 10 different regs in my experience diving. This one is easy to breath with and adjust underwater. The valve seems to be sturdy, is easy to connect/disconnect and works very well.

Questions and Answers for Oceanic NEO CDX5 Regulator with Dry Valve Technology:
I was interested in purchasing this reg with the octopus, do you have this in a DIN version with dvt?
Bill (Certified Scuba Instructor at Scuba.com)
The DVT is only available in a yoke style regulator.
Simply Elegant. 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.
Pneumatically balanced second stage with virtually no breathing effort Advanced composite construction for rugged durability and light weight - our lightest second stage at only 5.7 ounces (without hose) Ergonomic Adjustable Venturi Switch (A.V.S.) for simple Dive/Pre-Dive Adjustment Patented Orthodontic Mouthpiece with high-density bite tabs for increased comfort and reduced jaw fatigue Paired with either the FDX-10 or CDX-5 Over-Balanced Diaphragm First Stages with an option to include Oceanic's DVT (Dry Valve Technology) Nitrox compatible to 40% out-of-the-box Now available with MaxFlex Hose which is a lightweight, flexible, Braided hose designed to outperform and outlive traditional rubber hoses.
Dry Valve Technology (DVT)
DVT is a revolutionary regulator technology designed to automatically eliminate moisture and contaminants from entering your first stage, even if the dust cap is accidentally left off.
DVT eliminates corrosion of critical internal components, bacteria, hose deterioration, and damaged gauges and computers.
Pneumatically Balanced Valve. 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 a mechanically balanced second stage with a higher rate spring. So the total effort to breathe the pneumatically balanced second stage is indeed less.
The spring force must be just enough to overcome the difference between downstream air pressure and upstream balance chamber 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 airflow from the valve to the mouthpiece, producing effortless venturi-assisted inhalation or creates enough resistance to prevent free flow on the surface.
Computer Optimized Design. The NEO was designed using the latest 3-D computer modeling techniques. This allows us the ability to model and test performance while still in the early stages of development. The NEO’s unique valve, deflector vane and housing design directs airflow from the valve directly to the mouthpiece, producing nearly effortless venturi-assisted inhalation.
Patented Orthodontic Mouthpiece with High-Density Bite Tabs. To further reduce jaw fatigue, the NEO features a patented Orthodontic Mouthpiece, designed to accommodate the natural overbite of the human jaw.
Nitrox Compatible. The NEO | CDX-5 is classified as being suitable for use with Nitrox breathing gas mixtures containing up to 40% oxygen by volume without the need for special preparation, cleaning or component parts.
Over-Balanced Diaphragm First Stage Forged from marine-grade brass, the FDX-10 features optimized air paths and angled hose ports for superior performance and comfort. A sealed Balanced Diaphragm design, Enviro Kit and optional patented DVT TM (Dry Valve Technology) isolate all internal components from the environment. 2 high pressure and 4 low pressure ports allow convenient and comfortable hose routing.
The CDX-5 high performance over-balanced first stage provides progressively greater intermediate pressure as depth and gas density increases. The center “pads” that the diaphragms act against are different sizes so the working area of the outer environmental diaphragm is larger than the working area of the inner diaphragm. As depth increases, more pressure is applied to the larger surface area of the outer diaphragm than would be applied to the internal diaphragm. The result is superior gas delivery under the most extreme conditions.
DVT (Dry Valve Technology) Ever wonder why they call it a 'dust cap' and not a water cap? Most dust caps are not designed to keep water from entering your first stage. Regardless of how carefully you may maintain your regulator, water entry is a much more common problem than most divers realize.
DVT is a revolutionary regulator technology designed to automatically eliminate moisture and contaminants from entering your first stage, even if the dust cap is accidentally left off. DVT eliminates corrosion of critical internal components, bacteria, hose deterioration, and damaged gauges and computers.
