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 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 haslowered the drop of intermediate pressure upon inhalation and has kept this dropat 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.

Comments about Cressi Cressi Ellipse Black MC5 Regulator:
This is my first regulator. Purchased to take with me on vacations. Two dive trips so far to Roatan and Aruba. Reg works well and was inexpensive. It is small and light, it travels well. No complaints so far. It breaths well with little effort. I would recommend it for travelling and a good starter reg.

Comments about Cressi Cressi Ellipse Black MC5 Regulator:
Great piece of machinery. Smooth breathing.
Most importantly, I found that moving the second stage lever to the "-" does not noticeably affect my breathing but do, and noticeably!, extends my down time, perhaps as much as 20%. One of my diving partners (we bought the same Cressi MC5/Ellipse Black) reports the same experience.
Also: it's light, which is a plus considering the airlines' restrictions on weight.
