Obviously, human\u003cbr\u003ebeings cannot breathe underwater, so instead, they rely on a portable respiratory\u003cbr\u003esystem that is self-contained.\u003cbr\u003eIn fact, that is what the word Scuba means: Self Contained Underwater Breathing\u003cbr\u003eApparatus. This apparatus allows human beings to dive to depths that were once\u003cbr\u003eunthinkable, and to stay under the water for long periods of time, depending on\u003cbr\u003ehow full the air tank is. Different mixtures of gasses are used in the air tank,\u003cbr\u003edepending on the length and depth of the planned dive.","brand":"unique5stardeals","offers":[{"title":"Default Title","offer_id":47155989643504,"sku":"2940012886989","price":4.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940012886989_p0.jpg?v=1763574058","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940012886989","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
