Surgical Bungee Necklace

[Scuba446]

Can ayone tell me the proper length of surgical tubing to use for the backup reg on a necklace - is it 3/16" ?

3/16" or 1/4" diameter surgical tubing should be fine. I changed from surgical tubing to 1/8" bungee cord, and now prefer the bungee.

I am using 3/16 bungee that i bought from heath74 from the board here.He sells it really cheap.Also check reef scuba as they also sell it.

Yea,
I bought both 3/16 and 1/8 from REEF, but thought that MAYBE 1/8 might be just a tad too thick.

Um, 3/16" is thicker than 1/8"... are you talking about the bungee?

 

[Scuba446]

I mean, I have 1/8 on it now and think maybe it should be 3/16? I am using surgical tubing and not bungee.

Yes, 1/8" surgical tubing can be too fragile, plus with age it will weaken. 3/16" or 1/4" surgical tubing will last longer.

If you are changing the necklace - still consider trying bungee. You can make a loop with the bungee that slips over the mouthpiece, rather than using a ziptie to attach the surgical tubing.

Here's the two alternatives (both work fine):

You may want to reconsider the attachment method. The nice thing about the other method is that if someone decides they want that reg, it will pull out of the loop with just a bit of effort. With the zip tie, you could end up up close and personal with a now more panicy OOA diver. Yet the attachment is solid enough not to come loose by accident.
