ScubaPro S270 Regulator

• The air-balanced design is intended to smooth out inhalation effort at varying depths and supply pressures – providing what the manufacturer describes as “effortless” air delivery, whatever the diver’s position in the water. 
• The techno-polymer plastics barrel with metal thread is designed to help save weight and provide a surface resistant to ice-crystal formation. The S270 systems are CE-certified to the latest EN250A European Standards for all diving conditions, including extreme cold water, says Scubapro.
• The casing uses a glass fibre-reinforced nylon core with anti-scratch PU outer layer to make it “sturdy yet lightweight” and capable of enduring years of hard use while reducing jaw fatigue and improving diving comfort. 
• The dive/pre-dive switch is said to be easy to use even when wearing thick gloves, while the compact exhaust T is “very efficient in minimising exhalation effort”. The Hi-Flow silicone mouthpiece has a large cross-section and, linked to a hose with an oversized bore, should maximise airflow.
• The S270 second stage comes paired with either the MK11 or MK2 EVO first stages. The former has a balanced-diaphragm first stage with sealed internal parts, to prevent water and pollutants from fouling the inner mechanism and to enhance coldwater performance.
