ScubaPro MK21 DIN First Stage Regulator

ScubaPro MK21 DIN First Stage Regulator

Designed for Travel, the MK21 First Stage is 20% smaller than the MK25!

A new compact, balanced piston-controlled first stage with exceptional SCUBAPRO breathing performance at a mid-range price.

FEATURES:

• The high airflow delivery to the second stage ensures unaffected breathing effort, no matter the tank pressure or depth.
• Very good resistance to freezing for a compact first stage, due to the external fins which optimize thermal exchange. 
• Compact in size(16mm smaller than the MK25) but not in features, this modern, striking first stage has a "smart" hose layout for perfect positioning and easy identification. 
• AIR BALANCED FLOW-THROUGH PISTON
• A balanced piston allows the use of lighter and more sensitive components, resulting in an ultra-fast breathing response, instant deliver of air on demand, and extra-high airflow, especially in low tan pressure ranges. 
• Balanced-piston first stages are the first choice of demanding deep sport divers and professionals. 
• 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 changing tank pressure and depth.
