For new technical divers who want to make their own necklaces

[Vicko]

To make it detachable you just don't tie a stopper knot, no need to make it this convoluted, just tighten the zip tie.
And I mean really tighten, I lost a mouthpiece at a really, really inopportune time because I pulled out the bungee and the zip tie got to much play.

I don't wear rings on my fingers, partially because I don't want to get one caught on something and rip the skin off.

Similarly, I don't like jumping off boats or doing anything with something really strong around my neck. Also if something catches that second stage and pulls it away from your face and then puts 60 lbs of force on it and loads up the band with all that force and then releases launching that second stage into my front teeth.. well that is something I will avoid if I can.

Also if you have to remove the scuba tank in an emergency, I don't necessarily want the entire scuba rig tethered to a strong rope around my neck.. rather have it pull out automatically if things go drastically south.

Maybe all those reasons make no sense to you, but for me, it is benefit/risk assessment.

Of course we can ask why it is necessary to have something that will withstand more than 10 lbs of force before detaching from the second stage? Is the benefit of that worth the risk?

I don’t climb (or dive) with rings on my fingers for the same reason. Degloving is quite a valid risk in physical pursuits.

Where I disagree is in the rest of the statement. The risk of the reg not being exactly (single BM, doubles, SM, CCR, SM CCR) where I intend it precisely when I need it to be far outweighs any of the risks you highlighted. Even a tight zip tie with an overhand knot is probably knot (hehe) going to behead you should you fall off the boat and your 20/22/24” backup regular hose somehow catches on some mysterious something.

If it helps, I was trained and mentored many people with the double fisherman knot method above before knowing better. I’d give you 99:1 odds that the risk of the second stage not being where you need it when you need it is far more severe than the preference to not need to take it off.

Well, we probably do different types of diving and we have both thought through the details of this issue.

I use something different than the bungi this guy uses, but I prefer the breakaway aspect. Apparently we arrive at different conclusions.

Thank goodness we aren't GUE or we would have to have a fight to death over the conundrum and then we couldn't dive anyway because we would not have a buddy after the fight.

Are you not performing technical diving? What about your diving doesn’t apply to the above discussion?

I don't see where the GUE thing comes into play. The reason you have your backup reg right underneath your neck is you want it to be there whenever you need it. Its entirely possible you discover the backup reg has detached unexpectedly at exactly the time you need it most.

One thing I see in scuba is most people endeavor to optimize their gear and their approach to make their dives simpler and safer. Unfortunately, its not uncommon for people to wind up optimizing the wrong things. Examples everywhere including spare air, gear remove and replace, console retractors. And now, detachable necklace regs. In the years I have been in scubaboard and separately, interacting with a vibrant local dive club, I have never heard of a scenario - beach diving, boat diving, cave diving and so on, that a detachable necklace for your backup reg was needed. Put a different way, I wonder if you are optimizing for a non-existent problem.

In a technical environment (this forum), what purpose does your breakaway provide? In what scenario underwater is that reg coming off your neck?

Leaping into a RIB in rough weather, you need to remove your gear and hand it up to the crew. Something you wouldn't be capable of doing if you don't remove the regulator from the necklace.

LOL, it is a regulator retaining strap. I got no more ammo to discuss this. I wear my pony reg on a necklace and use an Air 2 usually. My second stage hasn't fallen out of the necklace in the last 150 dives I bet, probably more than that.

And if you can't tell the GUE thing was a joke.. well ......

Use low-profile zip-ties.

Remove the necklace from your neck….

Bots…

I got a message from an admin that this person is not a bot. Which makes the responses all the more, um, interesting.
