Scubapro MK25 EVO 1st Stage Regulator – INT 232

The Scubapro MK25 EVO First Stage Regulator – INT 232 lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and extra-high airflow — regardless of how cold the water is. This is made possible with SCUBAPRO s exclusive patented Extended Thermal Insulating System (XTIS) that fully isolates the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over previous versions of the MK25 without compromising breathing performance.
