Combines a balanced diaphragm first stage with an SC cold water system with a sealed chamber and a light and compact second stage, that is a high performer in waters colder than 10°C. This premiere travel regulator packs maximum performance into minimum space. A true featherweight second stage, the Compact is built from lightweight techno-polymers to eliminate jaw fatigue.

The A700 CARBON is teamed with the MK25 EVO, widely considered the gold standard in first stage performance, and finishing off this premium air delivery system is a DLC (Diamond-Like Carbon) Black Tech coating. Put it all together and you have diving's ultimate muscle reg that looks great, is ultra-durable, and delivers the best breathing performance around.
