    Re: BOV QD Component setup

    QC4 is what ISC used to put on the Meg heads but discontinued their use. I have been told this was because there were a couple incidences of them becoming disconnected during a dive but that's all second hand. I would actually prefer a locking QD on the head since it's annoying to have to plug in the head when calibrating. It's either that or plug the LP hose.

    Hi,

    QC4 does not give enough flow for breathing, it can be used for diluent or oxygen on a rebreather but not on the BOV.

    I'm looking for opinions on how everyone likes to set up their QD's and hoses for offboard bailout. At this point let's just assume single offboard bailout, no deep bailout or anything fancy at this current stage.

    Currently thinking either Omniswivel QD at the BOV for size and weight and I won't need to be disconnecting it in the water, however I would like to be able to remove the hose easily. Other option is QC6 but they're massive and heavy for what it's being used for in my opinion. From there I had planned 40" hose routed along the loop and down the left side to a QC6. Bailout 1st stage has 11" hose to other side of the QC6. Which side of the connector is preferable for which hose? Male on BOV hose and female on 1st stage side? Other way around?

    Thoughts? Without getting into manifolds and switch blocks, etc. this seems the easiest. Unfortunately there isn't a decent video or post that I've been able to find here or other forums with images or video actually intact so I can't model mine after prior posts. I've seen a diagram that looks alright but if anyone has pictures of a solid setup I'd be very thankful.
    HERE IS A PHOTO.
    off board BO gas runs to BOV directly on left side & gas runs to manifold thru inline valve. That's been my setup for wreck & cave diving. shown is a QC6 fitting.

    Got it. It's been covered before but I could not get a "QC4" to yield a single search result. "QC4's" brought it all out.
    Thanks,

    Putting a shut-off sloder on the regular second stage is a good practice as the regulator is not always in you vision field and it could leak (for example while scootering).
    But on the BOV, the gas path should be free from any blocking device. You can hear and see you BOV 2nd stage leaking, you can always take off the QC6 to stop it if the flow is important.


    You are absolutely right, and it's caught me off guard before by being closed during practice. Once during every dive I flip to BOV at depth for two breaths, and found the valve off.


    It's only on there because I dive in a lake a lot, and spend time on surface gossiping. When mouthpiece is out, lever flipped to BOV to prevent accidently flooding unit, but the BOV free flows easily in this condition, which is why I added it. I've considered removing it and checking to see if BOV might need to be tuned.
