Combine the environmentally sealed MK17 Evo first stage with their best-selling S600 stage to get an extremely powerful regulator combination! The environmental seal on the MK17 Evo means that no water enters the first stage, so it's the ideal regulator for murky or cold waters as all the internal parts are completely sealed off to prevent freeze and free flowing! This means that if you look after your regulator set by rinsing it after every dive, it will last for ages!
The S600, with its lightweight fibreglass casing and metal valve housing,g is Scubapro's most popular second stage for a reason! Because of the condensation inside, the reg allows you to breathe moist air (no more dry mouths from breathing from a plastic regulator!). It breaths exceptionally well and has been designed with metal parts to last for ages!
