The point of a bungee backup is it is for the one wearing it and you want it around your neck. I too started for years with the loop over the reg. A couple weeks before I took Fundies the instructor went over our gear quickly at our local dive site. He grabbed mine and said this is no good then proceeded to show me how it was no good, because it could be removed, by pulling and pulling to get it off the reg. After a few more heartier tugs it finally came loose. I don't think he thought my install job was going to be that effective. Since it was a class requirement for gear to be set up a certain way I changed it to the way ScubaSam set hers up. After all Sam and I took the same class, just from different teachers in different states. Gear brand is unimportant, but gear configuration had requirements . Works fine either way, but for the agency I trained with knotted under one zip tie works, and is accepted.
 
I tie mine with the fisherman's not method, no zip ties and it has never fallen out. I have always liked the fact that the reg can be removed from the bungee with a sharp tug, but after reading these posts, I think I will double check that to make sure it doesn't come out too easily.
 
Tie this knot:

Slide the knots apart enough, put the mouthpiece of the reg through the center hole, and then slide the knots back together.

I don't care if someone snags it instead of the primary. I can reach the primary even clipped on. I'll ask the victim to swap with me, but it's more important that s/he gets air.
 
There are several considerations to the various ways of constructing a necklace. One, you would like it to be reasonably secure, so that you don't lose the necklace in the bottom of the gear bag or on the boat deck, or underwater. Two, you would like the mouthpiece to remain on the regulator, no matter what happens to the necklace. And three, you would like to be able to free yourself easily, should the necklace get caught in something in a small space -- albeit unlikely, this is conceivable, especially as the bungie lies across the back of your neck, where it's not easy to reach.

As the mouthpiece security seems very important to me, I will NOT use a single ziptie to secure the necklace and mouthpiece, nor will I let my husband do it. (He's a ziptie kind of guy, despite my opinions.) And since I can think of nothing beyond an annoyance that occurs on the very rare occasion that the necklace comes off the reg, I use the fisherman's knot necklace. I have had it let go a few times -- usually when I am taking my gear off in the water and have forgotten to take my necklace off first, which is a time when I don't mind it coming loose one little bit. I have NEVER had it come loose during a dive, since I started using the 1/8" shock cord. I have, once or twice in almost 1000 dives, had the necklace turn up missing at the dive site, because it came off in transport. I think I found it once on the boat deck, and on another occasion, I did a shallow boat charter dive with a loose necklace reg. I'm pretty happy with those statistics. For any "big" dives, I'm going to have spare bungie in my kit, so another necklace could quickly be fashioned, if need be.
 
I'll confess to using a variant of the zip tie around the mouthpiece and overhand knots at the end of the bungie. The variation is that I do NOT use the mouthpiece zip tie and the zip tie is not cranked down. I want to be able to pull the reg off the bungie without too much effort.

If, for example, something caught my necklace, I can pretty easily just pull one end out from under the bungie and then slide the bungie past whatever has caught it. IF, however, it was cranked down with the same zip tie that held the mouthpiece, I don't think I could do that OR the mouthpiece might also come off -- neither being what I'd want. In addition, the traditional full loop of bungie and sliding knots around the mouthpiece means I have a complete circle around my neck. If something was caught, I'd have to cut the bungie or somehow bring it over my head, dropping my primary, etc.

I think the way I've evolved is simpler and, perhaps, a tad safer.

YMMV

PS TSandM doesn't think I can pull an end out from under the zip tie -- test is about to occur, depending on which of us goes down to the very cold basement to grab a reg!

I'm interested in your method, but I can't completely visualize it. Are you saying that you use a second zip-tie (second to the one that holds the mouthpiece onto the regulator) and make a "loose loop" with it in the same place as the mouthpiece one, and then pull the main body of your knotted-end section of bungie through it (towards you) to make the necklace loop? So the knot size holds it, but the knots can be "scrunched down" to be pulled through?

I may have this completely wrong, but I'd like to be able to visualize it.

For fun I tied nooses on mine - one on each end of the cord. Snug them babies up around the mouth piece and yer good to go.


Just remember when done right a the purpose of noose is not to strangle but to break a neck. And do not forgot to go around 13 times :).

Apparently it's "off-topic" to mention an example of where a choice of bungee necklace approach cost a diver their life. Perhaps the OP would be interested to know of such potential consequences?... if so, I might suggest that he asks that question on the thread, making it thus "on-topic"...so that they might be better appraised of the pros and cons to the options thus far stated in the discussion.

If I have incorrectly assumed that the OP would be interested in why we chose our necklace options, rather than just simplistically posting what ​we opt for... then I do most wholeheartedly apologise...

No, in fact, I do appreciate hearing opinions (substantiated) as to why a method is preferred, as well as opinions (substantiated) as to potential issues
in configuration uses. Experiences and observations always help when explained.
