{"product_id":"s3-ac-arctic-cold-water-first-stage-regulator","title":"S3 AC Arctic Balanced Diaphragm First Stage","description":"\u003cp\u003eThe S3 AC is the Arctic edition of the S3 balanced diaphragm first stage, purpose-built for ice diving and the coldest water. Compared with the standard S3 it has been put on a diet — meaningfully lighter on the manifold or under a drysuit-clad shoulder — and its heat-exchange design has been completely reworked to draw more warmth from the surrounding water, resisting free-flow and ice-up when the thermometer reads near zero. The diaphragm layout seals the valve mechanism away from water, silt and ice crystals, exactly what you want under a frozen lake. Two grades are available: the silver S3-AC and the black S3-AC Pro.\u003c\/p\u003e","brand":"HOTDIVE","offers":[{"title":"Black \/ DIN","offer_id":44164211114058,"sku":"S3-AC Pro-D","price":409.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ Yoke","offer_id":44164211146826,"sku":"S3-AC Pro-Y","price":409.0,"currency_code":"USD","in_stock":true},{"title":"Silver \/ DIN","offer_id":44164211179594,"sku":"S3-AC-D","price":350.0,"currency_code":"USD","in_stock":true},{"title":"Silver \/ Yoke","offer_id":44164211212362,"sku":"S3-AC-Y","price":350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/5598\/6506\/files\/S3-D_e3b07180-7bd8-4b2b-a78a-4f8a5d2841ac.jpg?v=1789638277","url":"https:\/\/www.hotdivescuba.com\/products\/s3-ac-arctic-cold-water-first-stage-regulator","provider":"HOTDIVE","version":"1.0","type":"link"}
