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 & ultra-stable intermediate pressure, for an extremely punctual & consistent high delivery of air, ensuring unfailing performance. SCUBAPRO has brought innovation to the A700 regulator. Available in NEW Black Tech version, this regulator is not only beautiful & high performing, but incorporates a PVD (Physical Vapour Deposition) fi nishing process which, when applied on metal surfaces, increases ruggedness, scratch resistance & surface hardness. PVD coatings can also be found on critical military equipment, premium watches & tools. This finish is accomplished using Titanium Nitride & provides the following advantages: 2500HV hardness for signifi cantly enhanced anti-scratch effect (compared to chrome’s 900HV hardness & stainless steel’s 190HV harness). Unaffected by UV rays. 100% non-toxic. High corrosion resistance. Low friction co-efficient. Very low magnetic signature.
