This regulator, tested under the most demanding conditions, is the ideal companion for your dives. It is absolutely sturdy, extremely reliable, and high-performance, even in very cold water. The Abyss has been tested by the Notified Body INPP of Marseilles with binary (Heliox) and ternary (Trimix) mixtures to a depth of 100 m. The results are compliant with the recommendations of European Regulation EN 250. Breathing effort proved to be much lower than the regulation requires.
