- All Metal Technology
Outstanding mechanical resistance and high thermal conductivity make our metal 2nd stages extremely long
lasting and ideal for cold water dives. The high thermal conductivity of metal reduces the dry mouth feeling during the dive.
- Carbon Technology
Extreme light weight, exceptional mechanical resistance and high thermal conductivity make carbon the perfect material for the most demanding divers and every condition.
- DFC - Dynamic Flow Control
Minimizes intermediate pressure drop during inhalation thus maximizing gas delivery, especially under extreme conditions.
- Fluid Dynamic Deflector
Receives and properly directs the airflow from the bypass tube to the mouthpiece.
- Mesh Grid
Patented design which reduces the impact of water flow onto the second stage diaphragm, thus eliminating free flows even in strong currents.
- NCC - Natural Convection Channel
Increases cold water performance by creating a flow of water across the regulator. The flow is driven by the change of density in water with temperature.
- Small Size
Innovative diaphragm design and component layout result in tangible reduction of dimensions. Enjoy unique wearing comfort and easiest handling and storage.
- Superflex Hose
Extreme light weight and exceptional softness guarantee the maximum freedom of movement.
- Tri-Material Valve
Patented technology combines two grades of polyurethane on a brass core. Maximizes performance, safety and reliability.
- Twin Power
New, flow control manages the delivery rate of your gas, from natural breathing to power breathing. The former is the traditional way of breathing a Mares regulator, (VAD) while the latter (VAD+) provides an extra push when you need it.
- Ultralight Techno Polymer
Abrasion resistant and affordable, ideal for diving in warm and moderate water temperatures.
- VAD - Vortex Assisted Design
The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low pressure area in the center that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths.
One of a kind
• Hydrodynamic second stage shape
• Lateral exhaust tee
The revolutionary design of this scuba regulator 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.
