Regulators - 2nd stage

Your second stage regulator or demand valve is held in your mouth and delivers your air via a mouthpiece from the first stage valve connected to your cylinder. It will also exhaust your exhaled air and contains a purge button to rid the valve of any water that may have entered inadvertently.

You also have a second stage on your Octopus which is generally a bright colour such as yellow so it can be easily seen when clipped to your dive gear.

Special regulator designs are available to cope with different diving conditions such as very cold water. You will also find 2nd stage regulators that allow you to adjust the airflow to make it easier to breath through.

Generally your second stage regulator will be purchased as a complete set with first stage and connecting hose, however if you are looking for an upgrade or replacement then they can be purchased individually.
