This regulator is made up of the new 2nd stage Compact, combined with the MC9 diaphragm first stage and the Octopus Compact, that uses the same casing as the Compact model made from special hi-tech polymers, the only difference being the yellow front cover.

Regulator designed especially for cold water. Combines a balanced diaphragm first stage with an SC cold water system with a sealed chamber and a light and compact second stage, that is a high performer in waters colder than 10°C. This premiere travel regulator packs maximum performance into minimum space. A true featherweight second stage, the Compact is built from lightweight techno-polymers to eliminate jaw fatigue. Easy to pack and easy to dive, the Compact includes dive/pre-dive Venturi switch for managing freeflow and maximizing performance at depth.

Version technically identical to the T10 Master, but with a pleasing and durable satin chrome finish on the first stage and a brushed stainless steel cap on the second stage.
