Cressi Ellipse Steel - Mc7 Af

Cressi Ellipse Steel - Mc7 Af. This model has been designed mainly for use in cold water.

The MC8 diaphragm first stage comes with the standard issue antifreeze kit and the second stage is identical to the one used in the Ellipse Titanium.

The first stage of the Ellipse Alaska is the already famous and excellent Cressi MC8 model balanced diaphragm. It comes with the antifreeze kit, which provides an additional waterproof chamber, to screw onto the end of the first stage.

This chamber ends with a silicon diaphragm on the outside that seals off the inside from contact with water, while still transmitting any pressure variation to the inner organs, thanks to the flexibility of the material.

The antifreeze kit is composed of two main parts, both made from strong chrome-plated brass. There is a mushroom element inside, made from acetylic resin, which connects the external diaphragm to the internal one.

The use of the antifreeze kit completely eliminates any water seepage into the external part of the first stage, so not only does it prevent the formation of ice in this area, but it also prevents the formation of deposits and incrustations on the diaphragm and on the spring.

This provides considerable advantages for divers working in mineral-rich water or with lots of suspension (archaeological sites, port works, caving etc.)

MAX COMFORT
Comfort is always one of the primary design elements in Mares equipment. Mares through superior technology continues to research, innovate and upgrade your level of comfort before and during your dive. Equipment marked with Max Comfort bring this quality of comfort to the most up-to-date premier pinnacle.

IDEAL FOR TRAVEL
In today-s world of travel we are strictly confined by airline weight restrictions, therefore the design of your equipment needs to encompass elements to be travel friendly. Lightweight, streamlined, easy to pack and hassle free are just some of the elements included in the gear marked for travel.

DIVING CENTER
For almost 60 years Mares has experience in developing and producing diving equipment on superior level. This experience has led now into the set up of diving products completely dedicated to rental and Diving Center use.

TRI-MATERIAL VALVE
Patented technology, conceived and created to optimize performance, safety, and reliability. This brass valve is covered with a hard PU then the head is layered olecularly with a soft PU. Tri-material (brass, soft polyurethane, and -heavy duty- polyurethane) reaches a new level of durability.

FLUID DYNAMIC DEFLECTOR
This innovative deflector, developed after in-depth study and tests of fl uid dynamics, is engineered to receive and properly direct the airfl ow from the by-pass tube to the mouthpiece. Combined with the VAD it delivers a very natural and effortless breathing.

VAD - VORTEX ASSISTED DESIGN
All Mares second stages offer the unique patented VAD system. The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low pressure area in center that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths.

MESH-GRID
The patented mesh design of the second stage cover reduces the pressure of water fl owing onto the second stage diaphragm and minimizes free-flow. Even in strong currents it eliminates the need for a knob to -de-tune- your air delivery system to stop free fl owing: Advanced Technology through basic physics.

DFC - DYNAMIC FLOW CONTROL
DFC system minimizes the intermediate pressure drop during inhalation, making it possible to use a simpler and more reliable second stage. Any type of manual adjustment is not necessary, thanks to the consistency derived from first stages that guarantees a stable flow of air, even under extreme conditions.

Oceanic Eos Fdx 10 Int Dvt

Oceanic Eos Fdx 10 Int Dvt. Every breath is a dream come true. For over 30 years, Oceanics R&D group has taken advantage of new materials, development of rapid prototyping, advanced computer aided design systems, objective testing, and lots of open water dives in an effort to develop a regulator with the lowest measurable inhalation effort in order to provide air to a diver at the extremes of human capacity.

When engineering brought the near complete EOS in for conformational testing the results were so astounding, the laboratory stopped testing and performed a complete calibration of all instruments, and in re-testing the EOS was found to have a near effortless inhalation resistive effort on test after test. Perfect.

Comprised of precision-machined components and extensive research and design, the EOS regulator has achieved an incredible feat-lifelike breathing. Oceanic-s gifted team of design engineers has included effortless breathing, inhalation effort adjustments, and comfortable second stage swivels and orthodontic mouthpieces into a regulator that you can hold in the palm of your hand. This is far more than just another regulator in the eyes of the Oceanic team, this is a dream come true.

- Pneumatically balanced second stage with virtually no breathing effort

- Diver adjustable inhalation effort

- Patented Dynamic Adjustment automatically maintains inhalation effort throughout the dive

- Ergonomic Adjustable Venturi Switch (A.V.S.) for simple Dive/Pre-Dive Adjustment

- Stainless steel inline swivel for reduced jaw fatigue and comfort

- Paired with the rugged FDX-10 Over-Balanced Diaphragm First Stage featuring DVT (Dry Valve Technology)


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.

Diver Adjustable Inhalation Effort.
Most downstream demand valve regulators are calibrated during manufacturing to a single, middle of the road operation. Whether finning up current at 100+ feet or merely snorkeling out to the dive site, this factory adjustment may not be optimum for the wide variety of demands we place on our equipment. A simple twist of the adjustment knob enables complete control... Set the inhalation requirement to near zero when you need ultimate performance, or tune it for greater resistance as conditions or preferences change.

Patented Dynamic Adjustment.
A common objection to adjustable second stages is that divers cant 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 to 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 EOS. This mechanically balanced valve maintains your preferred breathing resistance throughout the dive. Set it once and the EOS automatically adjusts to make breathing as easy at 100 feet as it is at 30 feet - with no additional manual adjustment.

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 EOS 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.

Stainless Steel Inline Swivel.
Ever notice that nearly every picture you see of a diver, their regulator looks like it-s not the least bit comfortable- The EOS features an ergonomically designed stainless steel (no plating) in-line swivel for ultimate comfort.

Computer Optimized Design.
The EOS 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 EOS-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 EOS features a patented Orthodontic Mouthpiece, designed to accommodate the natural overbite of the human jaw.

Nitrox Compatible.
The EOS FDX-10 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.

FDX-10 Over-Balanced Diaphragm First Stage.
The 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 patented DVT (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 FDX-10 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.
