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.

A lightweight, simple, user friendly regulator, the MC9/Compact is ideal as a travel regulator, or for those divers who only really fall into the "summer weekend warrior" category.

Whilst it is a very fine regulator, the MC9/Compact struggles during the colder months, and will often need regular retuning to avoid issues of freeflow and/or ice buildup - the MC9SC/Compact Pro is the cold water compatible version of this regulator - however if you only dive warmer waters then this is a great reg, especially for those more petite divers who need something light that won't cause jaw fatigue.
