R 5 TEC, V 2 ICE are equipped with adjustable inhalation resistance knob. When the knob is
in a closed position, then the diver needs more effort to take a breath and the regulator is less
sensitive to sudden changes of pressure. When the knob is in an open position, then breathing
is easier. The regulation is smooth and anyone can adjust the knob to a needed position.

Intermediate hose – high quality, low pressure hose with working pressure of 1,7 MPa.
Joining the metal endings with the hose has been done with the help of twisted connectors
which guarantee high quality joining.
