The Airstream/Evoque reg combo is the best breathing regulators I own. Hands down.

The OMS AirStream 1 Evoque First Stage Regulator is an overbalanced diaphragm design with an environmentally sealed main spring chamber. The all sandblast finished chrome plated marine brass first stage regulator is a balanced diaphragm design which is environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.

The OMS AirStream 1 Evoque First Stage Regulator takes it one step further with the environmentally sealed main spring chamber. This further eliminate cold water from entering the spring cavity keeping the water further away from the internal mechanism and not allow the air flow of the regulator to be affected by the cold water. The first stage comes equipped with 4 LP ports and 2 HP ports. The LP ports route 30° down and 15° forward. LP hoses route close to the body but still allows for open water divers to route standard configuration. HP ports route down 45° bring hoses close to divers' body. Flat top reduces drag and creates streamlined profile. The OMS AirStream Evoque is designed to give the new diver and experienced diver the best possible hose routing options. Applicable to single cylinders, double cylinder configurations, stage bottles etc. Close hose routing reduces drag and entanglement. Regulator has larger interior gas chambers that allow for higher gas volume. Available in yoke or DIN with 4,350 psi (300 bar) service. Higher volume gas supply with reduced Work of Breathing (WOB) allows for an enjoyable experience for divers of every diving level.
