Finally also from Scubapro a very robust, powerful and low-maintenance 1 stage: The MK19:
Scubapro engineers have taken the best features of our previous air-balanced first stages and developed the new MK19 EVO. It has an outwardly sealed system to prevent water and dirt particles from entering the inner mechanism. The MK19 EVO is complemented by a new dry pressure chamber that improves icing resistance while ensuring consistent airflow and maximum durability in the coldest conditions. With a swivel head and five low pressure ports offering a variety of configurations, this 1st stage is suitable not only for professional, military and technical divers, but also for recreational divers who require superior cold water performance in a light, small and compact package".
Since the MK19 has a 5th medium pressure outlet and is very compact, it is predestined for a double unit set with first class hose routing!
