Diver-adjustable coaxial VIVA for powerful inhalation assistance & prevention of free-flow.
Diver adjustable inhalation control for personalized breathing effort.
Redesigned mouthpiece tube allows better exhaust airflow.
Available with either 232bar INT or 300bar DIN first stages.
MK25 / C300
The MK25/C300 has our ultimate balanced piston first stage paired with a reliable recreational second stage, making this a remarkable all-rounder system. MK25 first stage features include:
Air balanced flow-through piston provides constant & effortless air flow unaffected by changing tank pressure.
2 high & 5 low pressure ports on a swiveling turret.
MK25 FIRST STAGE
SCUBAPRO has been the leader in the evolution of piston controlled first stages since its beginning; the MK25 carries on this heritage with an array of patented features ensuring unfailing performance. The MK25 is a balanced piston first stage, our absolute top performer. It is a superior regulator thanks to its ultra stable intermediate pressure resulting in an extremely punctual & constantly high delivery of air. This means instant airflow at any tank pressure & water temperature for a real carefree dive.
THE PISTON TECHNOLOGY. The general advantage of a piston first stage lies in its reliability & reduced maintenance requirements, due to an effective but simpler mechanism with less moving parts. More importantly, no other design can reach the high air delivery rate of a balanced piston controlled first stage.
Air balanced flow-through piston- First stages with air balanced pistons deliver significantly more air to the second stage than any other first stage, while their performance is totally unaffected by the changing tank pressure. A balanced piston allows the use of lighter & more sensitive components, resulting in ultra fast breathing response, instant delivery of air on dem&, & extra high air flow, especially in low tank pressure ranges. The tired diver benefits from a smoother breathing regulator during the ascent or deco stop. Balanced piston first stages are the first choice of demanding sport divers & professionals. A balanced piston performs equally in warm & cold water environments.
Two opposite high pressure ports- The arrangement of high & low pressure hoses is crucial to diving comfort. Two opposite high pressure ports allow for an individual positioning of the first stage (pointing up or down). This allows the diver to position the gauges either on the right or left side & increases the freedom of movement for head & neck.
Multiple low pressure ports- For ultimate freedom in the arrangement of low pressure hoses, the MK25 accommodates five HF (high flow) ports on a swiveling turret, which allows for 360 degree swivel of hoses. High flow ports deliver about 15% more air than conventional ports.
DIN/INT first stage configurations- To ensure worldwide compatibility, all SCUBAPRO regulator systems are available in a 232bar INT version as well as 300bar DIN versions.
Externally adjustable intermediate pressure- Allows authorized SCUBAPRO service technicians to quickly fine tune or make adjustments after maintenance without the need to disassemble
