The MK25 teamed with A700, is an ultra-high airflow system for maximum performance in all diving conditions. SCUBAPRO is synonymous with piston-controlled first stages. Our MK25 underscores this heritage with an array of proprietary features and ultra-stable intermediate pressure, for an extremely punctual and consistent high delivery of air, ensuring unfailing performance.

SCUBAPRO has brought innovation to the A700 regulator. Available in Black Tech version, this regulator is not only beautiful and high performing, but incorporates a PVD (Physical Vapour Deposition) finishing process which, when applied on metal surfaces, increases ruggedness, scratch resistance and surface hardness. PVD coatings can also be found on critical military equipment, premium watches and tools. This finish is accomplished using Titanium Nitride and provides the following advantages:

• 2500HV hardness for significantly improved anti-scratch effect (compared to chrome's 900HV hardness and stainless steel's 190HV harness).
• Unaffected by UV rays.
• 100% non-toxic.
• High corrosion resistance.
• Low friction co-efficient.
• Very low magnetic signature.
