DIY Bungied Second - please post a pic

Peter, Wasn't suggesting you change... just discussing approaches to it

 

[idive2]

exactly like the photo is a post above... I have no idea why he would not slide the necklace further over the reg and past the mouth piece so as to use the lip to make it more secure.

Not sure if you are referring to my conshelf or not. It can be located either way depending on the level of concern of reg coming out. I have not had
it come out when using as pictured but have used it positioned on the back side of mouthpiece and zip tie as well.

I found myself thinking about this and I have a question:

First of all, I do understand (some divers') desire for the reg to be able to come detached from the necklace when desired. One potential reason was entanglement. When that came up, in my mind the necklace was getting entangled in something but were people actually thinking of the reg hose itself? I ask because if that happened, and you got the reg hose out of the necklace, then you would have a "free end" to work with.

OTOH, if the necklace itself was entangled, then even if you had a fisherman-type knot, and could take the reg out of it, the necklace is still a complete loop around your neck, right? And thus you are stuck to whatever you are entangled in? Is the thought just that that would then be more easily cut (with the reg not in it)? Or is it basically only the reg/hose that seem to get entangled, and so being able to get the reg out of the necklace is "enough"?

(I do see that a necklace design like Peter's is not a complete loop and can be detached, and so it would not go all the way around the neck; although if I'm visualizing it correctly, Devon Diver's loop would still be a circle, and he's the one who spoke of entanglement experience.)

I haven't dived around enough potentially tangley things to have an experienced opinion.

Don't know about them, but I'm taking it as "all of the above". I want to be able to remove my reg without issue. I'd like to be able to remove the necklace by separation. However, I know I can cut it safely with my z-knife.

If I'm going to approach my necklace with a cutting instrument, I'd just as soon my regulator and hose were as far away as possible.

Good points, and I did think of those. (But I'm still interested to hear your thoughts, so thank you ) It's just that yesterday I was nodding along, thinking "yep, me too" (because I have a fisherman knot holding the secondary reg), but then I realized.... hmmm.... if it's the bungie loop that's caught (and not the reg/hose), well, it's still a loop unless you cut it. So that's why I decided to post to ask more about it.

Thanks again for the input.

Yep, that's the big benefit. Also other situations, like the AAS reg hose gets snagged as you do your back-roll entry...

Yes, if the necklace itself is caught, then you have the benefit of disengaging the reg and removing it from the necklace before attempting the cut. This lowers the risk of a catastrophic error.

(I do see that a necklace design like Peter's is not a complete loop and can be detached, and so it would not go all the way around the neck; although if I'm visualizing it correctly, Devon Diver's loop would still be a circle, and he's the one who spoke of entanglement experience.)

You could combine Peter's and my ideas - tie knots in the ends of the bungee (rather than knot the loop) then zip-tie them together to form the loop. Then the loop becomes 'breakaway' also - giving another option (and preventing a continuous 'noose' around the neck). The entire necklace is then only as strong as the zip-ties that complete it.

I, personally, wouldn't want a dangling AAS (even on a short hose) inside some of the nookies and crannies I wriggle through in wrecks... so I opt for a knotted & zip-tied loop. Never had the reg fall out of that... and never come close to catching it on a water entry/exit etc.

I solely use the homemade 1/8th bungied system for my back-up second stage without ziplock and haven't had any problem whatsoever of coming out too easily or requiring too much pull to come out.

With this system, it is very easy to deal with snagged bungy necklace.....either cut it where you can see it in front of you using a Zknife or if in doubt...remove backup reg from system and loop hose through shoulder Dring, locate bungy necklace with right hand, remove main reg out of mouth using left hand, slip bungy necklace off your neck over your head being careful not to snag mask in the process, replace reg in mouth, resume breathing and then decide if you want to back out, cut and pocket bungy, secure cutting instruments and continue or get out.

I'm amazed we've got 6 pages of posts on homemade reg bungies when for a mere $ 8 @ Divegearexpress you can just go buy one that's equal to or superior to any of the solutions posted so far:

Why would you say that's =/+ the suggestions made so far?

You did read the bits of the thread that mention 'entanglement' hazards? Look at that big loop sticking out of the back of it.....
