Mares Instinct 12S Regulator

The revolutionary design of this second stage introduces a multiplicity of benefits.

The side exhaust deflects the exhaled breath, so that hardly any bubbles will ever crowd your view. The angled diaphragm combined with the VAD system ensures high performance in any orientation. Compensating openings in the back minimize the likelihood of freeflows in strong current. The 12S first stage features DFC system for consistent flow, Tri-material poppet to guarantee high reliability and four pre-oriented LP ports.
