    Of the attachment options mentioned, good that no one has suggested tying off to the "scooter" D-ring.

    About 8 days ago, a friend hooked his new "monster-sized" wreck reel to his front and center ring. Even in a compressed-neoprene drysuit he had a brutal giant stride off of the boat.

    He was so proud of his heavy duty and seriously unbreakable reel...
    ...He probably would have preferred a wee finger spool at that moment!

    I've actually got two of the Dive Rite bag pouches. I keep the openings faced in seperate directions so that I've got my primary SMB deployable by my right hand and a 100lbs liftbag/backup SMB deployable by my left hand.

    Both pouches connected by quicklinks to the plate. Set-up is both comfortable, out of the way, secure, and reliable.

    x-shorts...come on guys...just string a bellows pocket to your harness (or plate)...don't be a stroke!

    store your SMB(s) behind your bp out of the way...then remove attach to reel and deploy. I believe OMS even makes a system for this if you want to spend the money on it.

    about those DiveRite cambands with the d-rings, i've used em and they were great for attaching stages... how much did you pick them up for??

    I don't put spools on the butt D-Ring anymore. I had a incident where the spool came unclipped on the boat when I sat down on it. Problem is I didn't know it until I was down to about 50ft and it started getting harder to swim down. I looked back and it was completely unspooled. The spool was still on the boat and I was at 50ft so I let it go and continued the dive. The crew recovered it for me, but it was a lesson learned. That's why it's not recommended anymore. I put the SMB in the MC pack and the spools on my left hip D-Ring. Pockets don't hold enough spools for cave diving so that really isn't a great option unless you're just carrying the one.

    I used the X shorts with the SMB in the pocket for the first time yesterday. Needed looped bungee before I felt more comfortable with it there as velcro wasn't going to secure it. After doing that, it worked pretty well I thought. But what's an MC pack? (excuse my ignorance)

    An MC pack is a piece of material bolted to the backplate between you and the plate. It's trimmed wit an elastic part on the bottom and you can place an SMB or a lift bag in the space created. You can see a picture of one from Halcyon at the end of the page.

    Lift bags stow very easily when passed through two bungee loops passed through the bottom of the plate. They are streamlined and not prone to get entangled in that location and it involves minimal hardware - all very "hog". An open circuit or semi closed circuit SMB can be stored the same way - just fold it to the same lenght as the bottom of the back plate, roll it up and slide it through the bungee loops.

    Closed circuit SMB's are not ammenable to that method as the rigid inflators are almost invaraiably positioned across the width of the SMB to promote rolling lenghtwise, which eliminates folding the rolling the bag widthwise as an option. That means they end up in a pocket.

    I regard having a closed curcuit SMB dangle off a D-ring as the absolute last resort due to the line trapping, unrolling and general confusion with SPG, stages, etc that can occur. If a hip pocket is not available, then I would consider a pouch attached to the back plate on the side opposite where you'd place an argon bottle. You see technical divers clipping all manner of crap to d-rings, but that does not make it right. If it potentially interferes with easy access to something else on the D-ring, or increases the potential for line trapping, don't put it there. Adding d-rings to the base of stages etc, is just making things worse in terms of tangles and dangles.

    If a hip pocket or a pouch on the BP is not an option, put the closed circuit SMB on a butt D-ring but don't put a spool there - a reel yes, a spool no - for the reasons mentioned in previous posts.

    I saw something on the boat yesterday that would work great for an SMB and line attached there if the proposed use is as a Jersey upline. Visualize a 6" to 8" piece of 1/2" diameter PVC with flat plates cut from PVC drain plugs on each end held together with a SS eye bolt. Cut the 1/2" tube to the lenght required to roll your SMB between the end plates, add the lenght of line required, attach the SMB and roll the bag on top. Then turn the end plates down to the diameter needed to be flush or just slightly above the SMB then re-assemble and secure the SMB in place on top with a strip of inner tube, etc.

    The end result is a mini Jersey upline not much larger in diameter than your rolled SMB, but it is contained in a compact package that you can clip to your butt D-ring with either a double ender or a bolt snap installed inside the eye bolt with no entanglement worries. The bag is sent up just like you would with a cold water spool.

    How you use the SMB depends on the conditions where you dive and that impacts how you carry it. Personally in the great lakes or along the mid atlantic coast, I'd shoot a 100 lb lift bag for normal deco purposes and shoot a closed circuit SMB when things go bad and I need to be seen. If I am in a current and I am ascending off the anchor line, I shoot an upline attached to the wreck so that I stay on the numbers in locations where fog or sea state coudl make tracking a drifting diver difficult. If I am on the surface and drifting away from the boat, I'll deploy a closed circuit SMB to get the extra height and visibility. That means on the average dive the CC SMB stay in the hip pocket with the other "here I am" stuff and is not used at all, unless as a jersey upline or on the surface.

    If you dive someplace where drifing deco is the norm, your mileage will vary, but where ever you dive, adjust your configuration to optimize it to the conditions YOU will encounter not the conditions some other internet diver may encounter whereever he or she dives.

    Not all plates work well with an MC storage pack. The plate can be too flat to comfortably stow the bag. I use the loops on the bottom of the plate as DA described.

    Another simple option is is 2 loops of surgical tubing on your tanks to retain the bag

    The DR pouch on the plate works very well. I used to leave the strap of the SMB out, and the reel connected to it, but I like it better completely stowed away now.
