MK 17 First Stage The MK17's balanced diaphragm offers you peace ofmind with it smooth breathing mechanisms and maximum performance that doesn't diminish as your air supply does.

In addition to the VIVA, the air-balanced power inflator valve means you'll have a steady stream of air, regardless of the pressure in your tank.
