The ideal system for cold water or harsh conditions, tech divers and cave explorers just love this reg.

If you dive deep, dive cold, or often find yourself on silty bottoms or in less-than-pristine waters, the MK17 EVO/S600 is the reg system for you.  Or if you just like quality equipment that's going to last then you can't go wrong with this set up.

The new MK17 EVO is SCUBAPRO's premium high performance balanced diaphragm first stage. Engineered specifically for cold water and harsh environments, its internal components are completely sealed off from the elements so neither water nor pollution can get inside the chrome-plated marine grade brass body to foul the mechanism. This total sealing system also allows for a dry ambient pressure chamber which works to prevent freezing, provides better protection and improves performance, ensuring trouble-free operation no matter how cold or murky the water gets.

This new version is more compact than its predecessor yet delivers better breathing performance. Its improved internal design allows more airflow from the LP ports which have also been configured for optimum hose routing.

The S600 is a light weight second stage with a metal core making jaw fatigue a thing of the past and a reg that will last you a very long time.
