DIR- Generic Optimal necklace length?

[sunny_diver]

When my necklace bungie is too long, the second stage interferes with the drysuit inflation button. It also causes the long hose to get caught up on the backup reg when doing a S-drill.

When the necklace bungie is too short, my chin activates the purge button when I look down.

Is there a shortcut to finding the best length? Probably not, but it doesn't hurt to ask the internet.

Don't worry you'll get there

I made an intricate temporary test rig out of skinny bungee with slip knots

dive with a bit extra bungee on one dive, and then as your diving just pull the bungee through the zip tie a few times and tie an overhead knot until it feels right.

I throw my hood on and tie the necklace so that it sits under my chin that way, but this method is certainly more clever.

Short enough so the reg can be retrieved without hands. Chin on the purge button close.

Same issue here. I bought a long necklace and use a zip tie to clamp the extra length.

I’ve tried both silicone (7.5” dia.) and bungee (Scubapro S-Tek) on bare neck in warm water and get irritated rub marks on the back of my neck if I set it so I can insert reg hands-free. Is there a sleeve or something I should try around the necklace?

Wear a hood

Wear a hood

Never tried that, but might give it a shot. I also bought some “scuba fabric” and may try to fashion a sleeve around the silicone (it was less abrasive than the bungee, but still gave me a rash) one to see if that helps for when I am a bare neck in warm water.

A thin buff also works. On your neck under the water, atop your head if you end up waiting on the surface for a while and don’t otherwise have sun protection on (whether thick hair or a hat in your pocket etc).
