Regulator and Accessories

Scubapro MK25 EVO A700 is a very high performance regulator that is designed for cold conditions. The MK25 first stage is paired with the metal bodied A700 second stage for effortless breathing and excellent cold water performance.

MK25 EVO 1st Stage is one of the highest performance first stages available now, with a dramatically evolved balanced piston first stage with 30% increased freezing resistance, greater inhalation sensitivity for ultrafast breathing response, instant delivery of air on demand and extra high airflow no matter how cold the water temperature. The balanced piston design is more than capable of supporting a whole team of divers simultaneously without faltering. The sleek body has heat exchanging fins incorporated into its design to aid dissipation of the cold generated by the first stage as it works. The piston and main spring have been specially coated with an anti-freeze layer to improve cold water performance and reliability. The MK25 provides two high pressure ports and five low pressure ports (four around a swivelling turret and a high flow port of the very end of the turret).

The A700 2nd Stage features a full metal housing that is designed to offer excellent cold water performance as the metal construction allows the cold to be transferred to the surrounding water far quicker and more efficiently than normal plastic housings. The A700 allows the diver to independently adjust the Venturi and inhalation resistance. The Venturi control adjusts the flow of air within the housing, directly it toward the mouthpiece for optimal flow or toward the diaphragm to aid closing the valve. The inhalation control increases or decreases the tension on the valve spring, making it harder or easier to breathe (the default position is tuned to provide optimal performance).

The new S620Ti embraces the best features of the renowned S600 in an upgraded, state of the art design. Smaller and lighter than the S600, but using the same sized diaphragm, the S620Ti delivers excellent performance. Work of breathing has been reduced by 37% over the S600, providing effortless airflow under all dive conditions!

The full titanium inlet tube is ultra-light, and excellent corrosion resistant. The large purge button improves water circulation, and the new exhaust tee increases performance while directing bubbles out of the field of view. In all water temperatures, in all dive conditions, this new regulator system is a winner.

S620Ti Features:

• Titanium barrel is rugged, anti-corrosion and lightweight for long-term reliability.
• New exhaust tee increases performance while directing bubbles out of the field of view.
• Newly designed Compact Hi-Flow mouthpiece, exclusive to the S620 Ti, is mounted on an enlarged mouthpiece pipe to improve airflow as well as mouth comfort.
• Airflow at 2900psi/200bar: 1850 l/min.
