    Yes I meant tucking in my tank bungees. I prefer a hog loop over straight from the tank. I have done both. With the hog loop the reg just hangs around my neck nice and high. Also when I ran straight off the tank the length of hose tended hang low when clipped off. The hog loop no matter how I move or what I do the hose stays tight on my chest, and is just like I use in BM so things stay the same.

    With single tank SM I just run everything off the left tank and have both hoses behind my neck.

    Eiter was its a 7 footer and a bungee necklace. I prefer to keep everything in my SM gear as close to my BM gear as close to each other as possible. I have never had a problem with the hose tangling on anything because I have nothing for it to get caught on.

    As for swivels I use the dive rite 90 degree elbows on both regs.

    It's the new Hog left hand second stage. I m not sure of the swivel manufacturer. I got them at DEMA and they are excellent. They allow the hose to drop straight to the tank with absolutely no binding. I need to get a couple more since I am constantly switching between single back mount and side mount.

    OK, I just finished making shorter bungees so I am ready to go diving! It's kind of stormy here in the Keys, so I hope I get wet! Heading to Pennekamp for a shore dive.

    That's pretty much it, except I run the webbing on top of the larger Nomad wing.

    Marci, on the other hand, runs her bungees under the JT wing as it has a solid cover over the top.

    Rather than try to fix a tank trim issue by doing something to the harness, I prefer to just fix the tank itself. For travel we often end up with AL 80s, and as such we just use cam bands to secure the lower end of the stage rig. Then we add a 2 pound weight to the tail of the cam strap snugged up just outboard of the buckle and tail to the boltsnap. It holds the tail of the tank down and keeps it rolled in close to the body.

    We use two 5 footers as well. I normally run the left hand hose around the back of my neck to a bungee necklace. This leaves a short loop of hose under the upper band on the tank. However in tighter areas or in situations where I may be more likely to remove the tank, I'll just route it straight up to the left shoulder D-ring and clip it off - the same as I do on the right hand tank. This leaves a loop on the tank about equal in length to an LP 95 and is very clean. Miflex hoses are too torsionally rigid and won't lie next to the tank so they are, IMHO, a non starter in this application.

    Also IMHO, a 7' hose is a bit too much to keep neatly on the tank, while a 5' hose just needs one down and back loop and is quite clean if you ensure it is torsionally happy and lies against the tank.

    I take care to route the hose to the inside of the tank so it is between me and the tank as it is easier to re-stow or shorten the hose length feeding off the tank and more importantly, it prevents you from scraping/crushing/abrading the hose between the tank and the cave wall in restrictions.

    I have not had any issues with clipping or re-clipping the rear bolt snap through the loop of hose, but that's a produce of both how it's routed and a minor degree of care to ensure you don't clip through the loop and impede the ability to fully extend the hose. I think this is a much greater risk with a 7' hose and the double loop of hose involved.

    Having to share gas with another diver, especially another side mount diver is probably a very low probability event, but I like having the ability. And, with a 5' hose that is in essence "adjustable" in terms of length from the tank you the d-ring or mouth, you eliminate all the proper hose length futzing that comes with a fixed length short hose.

    My one negative observation is that if you use a 5' hose on shorter tanks and are not careful with the torsion when setting it up, you can create a sharp loop that loops around the base of the tank and over the other side, causing the hose to hang up when you try to extend it full length. It's easy to clear but it takes a few seconds to feed some slack back down the tank and flip the loop over.

    Another caution is that you want to test your 5' hose to see it it's really enough to share gas in tandem through a tight restriction. In our case, we've found 5' is just enough, but the trailing diver really has to tuck in tight. For some divers/teams, it might not be enough.

    This thread is kick ass.....I certified open water sidemount using the Hollis SMS 100 w/ the included bungees and aluminum 80 tanks. I now have in my possession an Hollis SMS 50 to which I have mounted ring bungees. Gonna try that out in the pool tonight and see how it works versus the standard loop bungees I used in training. I'd really like to also try ED's old school bungees on the SMS 50....wonder if there's anyway that could be accomplished?

    I tried a five foot but did not like it. By doing a hog loop I only need to put one wrap on my right tank with the seven foot hose. Same as if I am single tank, one loop. I have never had a problem in either configuration with snapping the tank ends through any loop because they are snug against the tank with two bands. I don't see any handling problems with this setup. Ymmv.


    Scuba127, you can mount an old school setup to that system. If you look at my UTD setup above you will se what I made. My webbing is in a T shape and theodore part goes up the webbing to a trig lose that holds it in place.y wing has tabs for the bungee to through using a standard single bungee setup. My webbing rides right under this and I use inner tube on the webbing and I run it through the tabs to hold the wing in tight.

    That's how I managed a 7 ft hose when I carried one in side mount. The downside is that you've got the hose around the back of your neck with no other really good options.

    In some circumstances, such as very low areas with lots of texture on the ceilings, it's possible to snag the hose, then have to back up a bit to clear it. Those are situations where I prefer to route the hose straight up from the tank. I can manage the switch from one to the other with a 5' hose, but it's a bit more complicated with a 7' hose, especially if things are already snug.

    Hitting several points in one post for several posts:

    As far as trapping the hose, that was when I thought JamesK was looping around the butt of the tank, so my fault for sowing confusion. I never have problems when inner tubing the extra hose length against the tank. But I do have problems with a 7 footer needed more than one loop to eat up length. A five footer needs just a single loop, while the 7 sometimes needs more than just a pull (for me), which could make for problems. Once I did a couple dives the 7 Foot hose needing more than a simple single loop (and I verified that PADI was allowing 5 foot hoses), I just went to the 5 foot hose. (Again no caves for me, so 5 foot is fine.)

    DA's point about the miflex having memory is one where the Hog Loop makes it less of an issue, for me, but with Miflex, the memory issue is always possible.

    Swivels, swivels: I cannot reliably make 90 swivels work, because of the different second stages I have to work with. What a customer may bring, including some of those tiny second stages means that a 45 or a 120/70/80 (the same thing but with different manufacturers labeling it differently) work for the behinf the neck loop, but 90's don't fit with a loop around the neck. Same thing is true for big headed people. Underarm (in BM) or direct from the tank (in SM) a 90 swivel works but around the back of the neck, the 45 or the 70/80/120 is necessary.

    The problem with the 45 is that if it is a direct route, it's not a good lie. So I have found the 120/70/80 to be the best since it works with the behind the neck (which 90 does not), and direct from the tank (which the 45 does not).

    I finally dove the choker clips today off of Cannon Beach at Pennekamp State Park here in Key Largo. Left side was run with a yoke tank and a zip tied SS butterfly clip. The restraining bungees for the hoses were 1/8". I used a yoke=> DIN adapter, and everything worked well. Right side sported a hose clamped SS Suicide clip and a din tank. The restraining bungees for the hoses on this tank were 3/16". I clipped bottom first/top second as well as top first/bottom second both on land and in the sea. Both were far, FAR easier than stretching the bungee around the valve and I have never had my tanks this tucked in. Vis was way too bad to take pictures. In practice, the butterfly clips were far easier for these hands to manipulate going on and off, but the hose clamp on the suicide clip stayed where I put it. I made new clip harnesses yesterday for securing the SS butterfly clips to the neck with a hose clamp in anticipation of this. I also used 15% silver solder to braze the 10 gauge copper wire together for a secure connection.

    Based on today's dive, the winner is a hose clamped SS butterfly clip using three 1/8" restraining bungees.

    Materials needed (per tank):
    1- SS Butterfly clip (Reefscuba #RS8600-S).
    1- 6" of 10 gauge copper wire bent into clip harnesses (silver soldered).
    1- 9/16" extra large SS Bolt Snap (Reefscuba #RS4280-S).
    1- 32" of 1" wide webbing for the main strap (Reefscuba #RS113-BLU) (2" folded over center of one triglide with 1" square sewn).
    1- 14" of 1" wide webbing for the bottom tank strap (Reefscuba #RS113-BLU) (2" folded over center of one triglide with 1" square sewn).
    3- 1" wide triglides (plastic) (Reefscuba #RS913-P).
    1- 15" of 1/8" bungee for the top hose bungee. Tied as a prussic (two grape knots).
    2- 24" of 1/8" bungee for the other two hose bungees. Tied as a prussic (two grape knots).
    1- Tank cam strap. (I used Dive Rite's 1 1/2").
    1- D-ring to match cam strap size.
    1- Triglide to match cam strap size.

    For the SMS100 bungees I used (per side):
    1- 2" SS Ring (Reefscuba #RS1017-S).
    2- 2" SS Quicklinks (Reefscuba #RS1015-S).
    1- 15" of 3/8" bungee (10 inches long after folding 2 1/2" on either end and using two zip ties to secure each end).
    4- 3/16" wide zip ties.
    2- 2" of 3/4" Heat Shrink Tubing (Used over the zip ties to eliminate any sharp edges or loose bungee ends).

    Thanks for that exhaustive list (I would love to see pics of the setup as always.)

    So many times I create something and then can never remember quantities or lengths. This is as much for me as for others trying to replicate it. I'll post more pics as soon as I get a chance.
