The MK25 teamed with our exceptional new A700, offers superior ultra-high airflow system for maximum performance in all temperatures and diving conditions.
SCUBAPRO is synonymous with piston-controlled first stages. Our MK25 underscores this heritage with an array of patented features and ultra-stable intermediate pressure, for an extremely punctual and consistent high delivery of air.
The MK25 balanced piston first stage is our absolute top performer, making this system our very best.
Air balanced flow-through piston provides constant and effortless air flow unaffected by changing tank pressure.
Newly polished chrome edition, available uniquely with A700 system, with 5 low pressure and 2 high pressure ports plus swiveling turret for convenient arrangement and personalisation of your gear.
Anti-freeze protection for all diving temperatures and externally adjustable intermediate pressure for easy maintenance.
