About Cressi Ellipse Black MC5 Regulator

The Ellipse uses an elliptical housing for the second-stage regulator which is made from hi-tech polymers. All the internal components of the Ellipse are a dependable high performance downstream valve design. Once the valve has open the air is channeled by injection to the liquid silicone mouthpiece creating a VENTURI-Effect enhancing the performance. On the top of the housing there is a flow deviator that acts on the VENTURI-Effect, with dive/pre-dive switch.

The Balanced 1st stage MC5 Hyper-Balanced Diaphragm Actuated 1st stage has a lightweight body covered by a protective techno-polymer elastomer shell. The regulator is equipped with three low pressure and two high pressure ports. Internally the 1st stage is coated with an anti-friction anti-corrosion material that reduces resistance and allows the critical components to move freely. This makes the components perform and last longer between annual servicing and increases performance.

Research on internal air passages and incorporating a special assist chamber has lowered the drop of intermediate pressure upon inhalation and has kept this drop at a minimum, guaranteeing higher performance in any situation. Hyper-balancing allows for an increase of the intermediate pressure at maximum depths and when experiencing low pressure in the Scuba cylinder, offering higher performance at maximum depths and during the ascent phase of the dive. The Regulator comes with a Low Pressure 3/8" Threaded Hose, weighs 26.91oz (763g) with the Hose, includes an Owners' Manual and is covered by a Limited Lifetime Warranty.

The Cressi Ellipse Black MC5 Regulator is commonly used for Warm Water and more. The Cressi Ellipse Black MC5 Regulator is popular because customers like the following qualities of the Cressi Ellipse Black MC5 Regulator: Adjustable, Comfortable, Effortless breathing.

        Very easy breathing and noticeable less air consumption as compared to my last reg.

        The flow adjuster seems useless, but other than that 0 complaints....

          My wife got this from me as a gift and she fell in love with it. It is easy to regulate air flow and once she changed the mouth piece she says it's perfect.

          Comments about Cressi Ellipse Black MC5 Regulator:

          6 months after purchase and about 50 dives later - (don't ask me how) the second stage LP seat felt out (did never open the unit) could put it back in and when I tried to adjust the (primary second stage)the octopus(same model) suddenly started free flowing, to me this means that the high pressure seat is worn, I live in Japan there is no Cressi dealer available so I will have to send it to the US for service all is just hazel especially after such a short time.

          I a have a total of three units and wonder if the other 2 also soon start free flowing...

            I teach a variety of scuba classes and I purchased these to let the students get comfortable with a quality regulator. I have enjoyed this regulator myself and have had solid responses from my classes.

            It fits comfortably. I have done over 100 dives with it. If you are at certain angles it doesn't allow you to breath easily.

            Questions about this item:

            Shopper  Why Did You Choose This?
            MR A  Hi name is Bruno Andujar,I am Scuba Diver. I bought this item because the price and quality is good. I will use for my dive school and shop as well.
            COLBY J  I assume the 2009 recall of the MC5 does not apply to these being sold now, is this correct? Recall due to: "Partial obstruction of the High Pressure (HP) port can produce an inaccurate reading on the pressure gauge, resulting in a slow descent of the needle in the pressure gauge."
            PETER K  We were unaware of the recall from 2009 ? ( I assume over that period of time there should have been a " fix " by now ? ) Anyway, for a budget regulator, octopus, gauge package we felt it was a good buy !! I purchased it for my wife and she used in in Cozumel on February for 5 days of two tank diving and the pressure gauge worked perfectly all week.
            Shopper  would you use this product in cold water at deep depths?
            KELLY T  I've used this product down to 40m and in 13 degree celcius water. Breathing was always smooth. The only problem wih the ellipse is if you are upside down or in positions that are't "normal" the air flow gets slight difficult.
