After four years of development, AERIS is proud to introduce the ultimate mini-breather. Scoring off the charts in Scuba Diving Magazine's Scuba Lab Regulator Review, the ION performs outstanding compared to its competition.

The pneumatically balanced demand valve along with a highly responsive design allows this regulator to provide a high volume of airflow with even the slightest inhalation effort, making it seem nearly effortless to breathe at any depth. All in a second stage barely wider than the mouthpiece? The ION means business as it comes equipped for any type of dive conditions, cold or warm. Following the rules of the sea, or should we say the rules of the C: Compact – Comfortable – Customizable; the ION is a diver's dream.
