While you don’t need to dive less-than-pristine waters to appreciate this system, it’s a great choice for cold water or harsh conditions, which is why tech divers and cave explorers just love this reg. The compact MK19 EVO is completely sealed off from the elements, ensuring trouble-free operation no matter how cold or murky the water gets. The G260 is the most imitated air balanced second stage of all time. It features metal internal components and a left-right hose attachment option, making it a great choice for tech diving configurations and a consistent top-of-the-line performer. Put them together and you’ve got a winner.\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003cdiv class=\"field-item even\"\u003e\n\u003cul\u003e\n\u003cli\u003eRugged reinforced
