The unit has the same functional princples. It is based on a demand system and can be bypassed manually. For the oxygen addition the CL is mounted on a demand regulator thas has been found in a scubapro second stage. To prevent the counterlung form collapsing it is equipped with a stainless spring. A nice and simple design. |

The counterlung is made of plastic but
will be replaced by ortlieb waterbag of 10 liter. |
