    I use a loop of bungee (the white stuff from a marine shop and NEVER the black stuff from a dive shop, since it does not stretch enough) but I have it running over the wing like an Armadillo rig. On this bungee loop I have one of the oversize bolt snaps attached with a quick connect.

    I use a pretty much standard rigging on my tank with a oversize bolt snap secured to the bottom and the top. I like the oversize bolt snaps because I can get my finger inside the attachment ring while using my thumb and it makes one-handed operation easy.

    when I gear up I can just clip the top snap ring of the tank to the oversize ring of the snap ring on the bungee that is connected to my shoulder d-ring. this gives a hard upper connection on the top to be able to walk without putting so much weight on the bungee. I can either pull the bungee around the tank valve now or wait and do it during the decent. the bottom tank snap ring clip to the stand under my rEvo.

    This way after the dive and waiting for the boat I can pull the bungee off and unclip the bottom of the tank. this leaves the tank with just a single clip on the shoulder d-ring that I can use one hand to unclip and hand up the the DM while holding the ladder with the other hand. Very quick and efficient.

    When cave diving, I do not use the upper bolt snap and rely only on the bungee over the tank valve.
    Plus one. Also its very easy to set up when kitting up on a rocking boat when all you want to do is just get in the water asap.

    Do you have any images Cathal/Dsix be interested to see setup?

    Dived this weekend with the new stage control bungees and relocated bottom D-ring. Was amazing, the stage is pulled back under my armpit and was streamlined, especially on the second dive where it contained 140 bar, so would normally get floaty. The stage never got in the way when inside the wreck and felt snugly tucked away. Was easy to get to when needed at deco; just grab it, pull forwards and disconnect the bungee.

    I saw, on a small monitor, a video of me with the stage and it appeared to be typical sidemount. I’m hoping to get a screenshot/print of that vid for reference.

    So a massive success raising the question of why doesn’t everyone do this!

    What thickness of bungee did you use?

    6mm.

    Thinking is that it needs to be stretchy enough to easily manipulate in the water but strong enough to put tension on the stage. Or, put another way, my sidemount 8mm bungee's too strong and is a sod to manipulate with gloves on.

    Is the new D ring one of Andy Gorrings creations?

    I've just done my ADP and the stage getting in the way is a pain. A couple of CCR divers in my club have some bungee off the backplate that comes under their armpit and connects to the shoulder D ring.

    From this is a large SS split ring which the stage is clipped to so it is further back than a usual setup and leaves good access to pockets etc.

    It seems to work well and I'm gon a give it a try. Will also have a play with this too. Glad to know it's not just us stage handling newbies that are getting frustrated.

    I believe the angled D-rings are these - https://www.divingproducts.co.uk/sho...product_id=354

    I've modified my backplate and added a Left-hand bungee. Also some annotations and pictures...

    I dived the bungee system the other weekend for a couple of dives and found it to work well. Sure, a couple of dives isn't a lot to tell, but it's one hell of a lot better than some floating abomination that results in diving half-filled tins. I've added this to the RHS of my backmount harness as I need to control a bottom stage I'll be using next weekend. This will be emptied about half way into the bottom phase, so will be exceedingly floaty. Thus I've added a forward sliding D-ring (actually it's an O-ring) which is on the waist belt. The same thing could be added to the LHS

    Will report back on how it all goes.



    Bungee size - first knot
    I found 25cm of 6mm bungee worked for me. It will obviously need adjusting for different sized people, hence the use of a (modified) fisherman's bend which will allow for the length of the loop to be adjusted. This is why I've wrapped some tape around the ends for now. Once I know the optimum length, I'll replace that with some binding.

    The purpose of the tail is to grab the bungee and pull it on to the stage. When wearing dry gloves, you don't want anything to snag (=pinch, cut, rip) your gloves. Again, with time, the length may be shortened.



    Bungee second knot


    Bungee knots closeup
    The first knot is a double overhand knot. This will tighten up on the 'free' end - strangle it. The second knot is a single overhand knot which acts as a stopper. It's not a proper fishermen's bend in that the tension's only on one end, not both ends as in the true fishermen's bend.


    Bungee complete
    Quick link shown.


    Harness chest strap
    This shows the quick-link used to attach the bungee. It's finger tight, so can be easily removed when not needed (e.g. the RHS).

    There's a second bungee tied to keep the stage bungee in place. This means that when you put it on, the bungee will always be in the right place, not trapped behind your harness.



    Harness waist belt (RHS)
    This uses a descending D-ring. This is the main difference between the backmount and Sidemount camps: the sidemounters like to have things streamlined and have discovered that the waist belt should actually be a hip belt to have the stages lower on the body, i.e. under the armpits. With backmount, the backplates are relatively short and have a waist belt that's too high to mount stages. Also, as the bungee puts tension on the stage, pulling it backwards, the traditional D-ring will be twisted. Thus the descending D-ring; both lowers the bottom mount to the hip and acts along the line of tension.



    Complete harness configuration
    Have fitted a traditional (albeit smaller) umbilical battery on the RHS.
    Yes, fitting a stage here may (will) interfere with longhose deployment. However, one will need to deploy the longhose in two phases: 1 - into the gob of the OOG diver; 2 - deploy the rest of the hose once everyone lives.

    Sone experience gained whilst diving this rig....

    The good news is it works well to control the stages. The bungees are pretty easy to use: locating them on the shoulder straps in the water; attaching them to the stages using the tail; how they pull the stages close to the torso. All good.

    The bad thing is he stage top bolt snap pulls on the chest D-ring, flattening it and making it hard to clip off other stuff. The solution to this, which I’ve implemented on my sidemount rig is to add a second D-ring under the existing one which is used only to clip off stages.

    I was diving this weekend on some deeper wrecks and using an ali80 bottom stage on the RHS. This is pretty much empty at the end and becomes very floaty — re-stowing the hose is quite a challenge to hold the cylinder down. The bungee system worked really well to keep this streamlined and in trim. Similarly, the LHS deco stages worked well being pulled up under the armpit.

    If the stages don’t have modular valves, the bungee can fall off the valve handle. I need to work out a better way of clipping of, possibly reversing the threading around the inside and out over the valve handle.

    So some tweaks required, but a great success.

    I thought the bungee held the top of the stage instead of the clip to the chest D ring? That's how side mount is connected up isn't it with bungee rather than clips to D rings?

    On another note with the issues you're having with the chest D rings being pulled flat, I've experienced the same already. I was thinking of getting some fixed angled D rings for the shoulder straps rather than the cranked D rings and the sliders, like the one in the picture.

    Do you think these would over come the issue without the additional clutter of another set of D rings on the shoulder straps?
