Scubapro MK21 First Stage is a compact, balanced piston-controlled first stage with exceptional SAcubapro breathing performance at a mid range price.
Compact sized (16mm smaller than the MK25) but not in features, this modern, edge-design first stage has a smart hose layout for perfect positioning and easy identification.
The high air flow delivery to the second stage ensures unaffected breathing effort, no matter the tank pressure or depth.
The MK21 also has a good resistance to freezing for a compact first stage, due to the external fins which optimize thermal exchange.
