I have a TUSA RS-240 regulator and the second stage has a knob for adjusting the air flow.
I am not overly experienced but I have played around with this knob, turning it all the way in both directions, both on the surface and while submerged and I can honestly say that I don't notice a difference in the ease of breathing.
I'm not experiencing any difficulty at all, I just wanted to see how the knob affects the air flow but, as I say, I can't tell a difference.
I have not dived deeper than 20m yet so I'm not sure if the effects only become apparent at higher ambient pressures or maybe I'm really just not experienced enough to notice the difference.
Any thoughts on this?
Also, if the position of the knob makes no difference to my breathing, will it affect my air consumption if it is turned all the way open? I'm keeping it in the minimum position simply because I can breath comfortably with it in that position and I think that I will use up less air that way. Just curious to know how this knob really works and how it affects my air consumption.
