About Cressi Ellipse Titanium MC9 Regulator

The Ellipse Titanium uses an elliptical housing for the second-stage regulator which is made from hi-tech polymers and titanium. The use of titanium and the polymer create a very lightweight regulator. 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 MC9 Hyper-balanced Diaphragm Actuated 1st stage has a lightweight body covered by a protective techno-polymer elastomer shell. Various parts of the 1st stage are made of lightweight titanium further reducing its weight. The regulator is equipped with four 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. Regulator weighs 31.8oz (901g) with the Hose, comes with an Owner's Manual and is covered by a 2 Year Warranty.

The Cressi Ellipse Titanium MC9 Regulator is commonly used for Cold Water, Warm Water and more. The Cressi Ellipse Titanium MC9 Regulator is most used by customers who consider themselves to be a Advanced, Beginner, Casual/ Recreational among others. The Cressi Ellipse Titanium MC9 Regulator is popular because customers like the following qualities of the Cressi Ellipse Titanium MC9 Regulator: Adjustable, Comfortable, Effortless breathing, Nitrox Compatible.

Good Price & Performance Poor Finishing

I'm a new diver, just clocked around 20 dives. Previously I used a loan set of Scubapro S600/MK25 from my firend. While others said that scubapro is effortless breathing, I don't see such a big difference when compared with this cressi reg. There is one reason I like this better than the scubapro, it is that my air consumption is better??!?! Is that even possible? For my first 14 dives I had been using the scubapro reg, but more often than not, I will be low on air before the pre-determin...

Bad assembled, bad o'ring

It was or bad assembled or factory problem. Since the o'ring was bad and it had a huge air leak. What ever the case, the people of Leisure pro should had revised and tested it when they assembled it.

Highly Recommended!


from San Salvador, San Salvador, SV

Great regulator! Very easy to breath and works perfect. What was curious when I assembled it with my octopus and gauge was th at the second stage was connected to the wrong port on the first stage! It was easy to change and also received comments at the dive shop that CRESSI normally does that...


Super nice, easy breathing and light 1st & second


from Kitchener, ON, CA

SO have the GOOD and BAD on this product and will be very honest in this write up. I bought two of these for my wife and I and your can't beat the price of these. When we received them they looked awesome, it was just the week before our trip so we were very excited to use them. Mine worked great, easy breathing, light in the mouth and with the custom mouldable mouth piece we also purchased was a dream for my jaw. Unfortunately my wife upon attaching to the tank, leaked from the 1st stage and we could do nothing about it. The dive master we were with would not touch it since it was brand new so my wife was unable to dive. The thought is that the main seal was bad or the main nut was not tight. This was super disappointing and very frustrating due to it being brand new. We lost the weekend of diving together due to this and, well I felt this should not have happened as the inspection process by the maker should have for sure caught this. Saying this however I cannot directly blame Leisure Pro as I am not sure it was their fault as I am pretty sure it was the manufacturer but in either case they were the retailer. So needless to say this second unit never even touched any water, my wife did not dive but I did and the regulator was a dream to breath. The customer service was awesome and when the president of the company heard of the issue he contacted me right away and apologies and said he would circulate this issue to the CSR group so they know of this issue. I have to say they were very professional and we shipped out the unit for return today, hoping we get the new replacement back soon so we can dive. I also have to tell you that not only is the shipping unbelievably fast on the initial purchase but the customer service is awesome. We added last minute an item I forgot to buy and they were able to add it to the shipment without blinking an eye though they had a lot to do to get it in. Al-in-all I am very pleased, wish I could have gave it 5-stars but only 1 out of 2 were perfect.


Great Reg


from St Petersburg, FL, US

I bought two of these, one for me and one for my son. We have dove 10 times so far, easy and smooth breathing at any depth and any tank air level. The mouth piece is a little small and soft for me but perfect for my teenage son. I replaced my mouth piece with a larger stiffer one now it's perfect.


Great regulator.


I like everything about this regulator. It is light weight and compact. It is very comfortable and easy to breath. I have made 11 dives with it so far without the slightest problem. You can't beat this regulator especially for the price.


High Quality Regulator


You can feel this is a high quality regulator. It even included an allen key for mounting the octo and inflator hoses. Enough ports to mount an additional computer integrator.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Does this regulator deflect bubbles away from mask or side exhaust?
ROBERT D  Yes it does... my son and I both have that same Reg. And they work absolutely perfect. If I had to buy another Reg. I would purchase the same exact one
JP P  Yes. The Ti MC9 has proven to be a great regulator for the value. I give it my full endorsement.
TY C  Yes and no. Yes it has bubbles directed away from regulator. Buts it's a compact reg so it's not spreading it very far. I have no issues with bubbles
Abdullah A  does it come with the hose?
Mike T  Hi Abdullah, Yes this reg comes assembled with the hose.
STEFAN M  Mine did, but that was 3 yrs ago.
E C  IT does come with the hose.
CHERYL D  YES. However before buying a regulator I would make sure someone in your area can service it. Other wise you will have to spend $$$ on shipping it to someone that can. I have gone to an Aqualung Micron Reg because no one in in my area can service Cressi anymore. ALWAYS check with your local dive shops and find out what equipment they service and support before buying anything. This could save you a lot of money!!
Shopper  Does it come with the necessary tools to thread the hoses into the first stage?
STEPHEN N  It does not come with the tool. You can easily by a dive wrench set and do it yourself or they can assemble it at Leisure pro. I have a lot of tools and have changed hoses or repositioned them on the first stage without problems.
CHARLES M  Mine did not but it is very simple with an adjustable wrench
SHAUN N  No. Your fingers are sold separately.
TY C  Does not come with any tools but mine is a 9/16 so any open end wreck, or other dive combo tool should work.
