It is certified \u003cstrong\u003eEN 250:2014 for cold water (A, below 10 °C \/ 50 °F)\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eGT Steel\u003c\/strong\u003e first stage is hermetically sealed: the chamber stays dry and the internal parts are protected from freezing and from silt and sand contamination. It is machined from marine-grade stainless steel, which is highly corrosion resistant and more sustainable than brass. An internal heat exchanger captures heat from exhaled air and uses it to warm the valve mechanism, as an extra barrier against freezing. The hyper-balanced diaphragm adjusts the air flow to the water pressure, and Cressi's \u003cstrong\u003ePressureSync\u003c\/strong\u003e technology keeps the intermediate pressure steady throughout the breathing cycle.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eMaster Pro\u003c\/strong\u003e second stage is pneumatically balanced. The stainless steel reinforcement on the cover, with ports that neutralise dynamic water pressure, prevents free-flow caused by current. The adjustable Venturi has two modes: \u003cstrong\u003eDive\u003c\/strong\u003e and \u003cstrong\u003ePre-Dive\u003c\/strong\u003e. The lightweight Miflex hose has a 360° stainless steel swivel.\u003c\/p\u003e\n\n\u003ch2\u003eMaster Octopus included\u003c\/h2\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eMaster Octo\u003c\/strong\u003e is built to the same standards as the Master Pro: in an emergency, your buddy's second stage must perform as well as yours. The shell is made of high-quality medical-grade plastic, treated to inhibit the bacterial growth caused by saliva and moisture, and resistant to salt water corrosion. The elliptical design fits the face and the large elliptical diaphragm reduces inhalation effort, especially at depth or with high air demand. An internal heat exchanger uses the diver's breath to prevent ice from forming.\u003c\/p\u003e\n\n\u003cp\u003eTo stop the octopus from free-flowing, the Master Octo has a stainless steel front insert with slots that neutralise dynamic water pressure, plus an adjustable Venturi that can be set to any position between pre-dive and dive.\u003c\/p\u003e\n\n\u003ch2\u003eMain features\u003c\/h2\u003e\n\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eEN 250:2014 cold water certified\u003c\/strong\u003e (A, below 10 °C \/ 50 °F)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eGT Steel first stage in marine-grade stainless steel\u003c\/strong\u003e, hyper-balanced diaphragm, sealed\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e2 HP ports 7\/16\" UNF and 5 MP ports 3\/8\" UNF\u003c\/strong\u003e, with a swivel turret and sidemount configurations\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003ePressureSync technology\u003c\/strong\u003e for constant intermediate pressure\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMaster Pro second stage\u003c\/strong\u003e, pneumatically balanced, with adjustable Venturi and inhalation effort control\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMaster Octopus\u003c\/strong\u003e with medical-grade plastic shell, internal heat exchanger and adjustable Venturi\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eInternal heat exchanger\u003c\/strong\u003e on both the first and second stage\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHighly flexible Miflex hose\u003c\/strong\u003e with a 360° stainless steel swivel\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eVersions\u003c\/h2\u003e\n\n\u003cp\u003eAvailable with a \u003cstrong\u003eDIN 300\u003c\/strong\u003e or \u003cstrong\u003eINT (Yoke)\u003c\/strong\u003e connection.\u003c\/p\u003e","brand":"Cressi","offers":[{"title":"DIN","offer_id":58784339231051,"sku":"CRPRG005201K0144NS","price":999.0,"currency_code":"EUR","in_stock":false},{"title":"INT (Yoke)","offer_id":58784339657035,"sku":"CRPRG0052K0144NS","price":999.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0861\/8121\/6587\/files\/cressi-gt-steel-master-pro-master-octopus-erogatore-din-300.jpg?v=1791736338","url":"https:\/\/mareshop.eu\/en\/products\/cressi-gt-steel-master-pro-master-octopus-regulator","provider":"Mareshop","version":"1.0","type":"link"}
