Inhalation Resistance Control Knob

Some second stage models are equipped with an additional

adjustment, which controls inhalation resistance.

This control knob, located beside the IVS/RVS switch, adjusts the

amount of effort required to start the air flow at the beginning of the

inhalation cycle. As it is turned "in" (clockwise), the opening effort will

increase. This will make the second stage less sensitive to sudden

changes in ambient pressure. Turning the knob "out" (anti-clockwise)

will decrease the opening effort to make breathing easier.

This adjustment is particularly useful at deeper depths, or in variable

conditions that affect the opening effort of the second stage, such as

strong currents or while using a diver propulsion vehicle (DPV). You

can use the inhalation control knob to tune your regulator to maintain

its peak performance throughout the course of your dive, or you can

leave it set in its mid-range position and dive with it as you would any

non-adjustable second stage.

For more information on using these adjustments, refer to the section

titled, Diving With Your Regulator, on page 31.
