1st Stage

The first stage of a regulator is critical to allow you to breathe underwater.  Its purpose is to take air from the tank and reduce the pressure to a level for the second stage to handle and provide air to the diver.  First stages, come in either DIN or Yoke styles depending on the type of tank you will be connecting too.  We have first stages designed for cold water, this helps to minimize the chance of the first stage freeing during use in very cold water.
