    Hello,

    I have a couple of questions on vernier handles on needle valves...
    1. Are Vernier handles necessary or more of a nice to have?
    2. What do you gain by Vernier handles?
    3. Won't just looking at the bubble counter to set the CO2 rate be enough for dialing in the flow?
    I am looking at getting the 54 series Ideal valve and debating whether to get the one with the Vernier handle or not.

    Thanks,

    George

    Vernier handle allows repeated dialing in.
    It’s nice to have and not necessary.
