The Scubapro MK19 EVO 1st Stage offers the best of both!!  The Sealed Balanced Diaphragm performance of the MK17 with the amazing hose configuration of the classic MK25.

The MK19 offers 5 LP ports on a swivel port, so is idea for many hose configurations, such as sidemount, twins and stage cylinders.

The Dry Sealed construction makes this a firm favourite with tech divers who want to environmentally seal their 1st stage. Such as cave divers who may dive in very silty locations.
