This design ensures the gas mixes completely while passing through the scrubber before being analysed by oxygen sensors, guaranteeing the diver always breathes the analysed gas.<\/li>\n<li><strong>Latest-generation technology<\/strong>, incorporating advanced materials and engineering, making the Shark one of the most modern and efficient rebreathers available today.<\/li>\n<\/ul>\n<p>The unit is equipped with a\u00a0<strong>Petrel 3 Shearwater computer<\/strong>\u00a0for ppO2 monitoring and dive data management.
