Cressi needs no introduction when it comes to scuba equipment. Since releasing the Polaris 4 regulator in the mid-1960, Cressi has continued to innovate and raise the standards of durability and performance in this category.

The AC25 is the next generation of the company’s popular IP adjustable balanced piston first stage. By combining this with the Master Cromo second stage, Cressi has provided divers with a regulator that performs well in any underwater environment.
