Hello divers.
"The backup must be instantly accessible. We hang it around the neck on surgical tubing or bungee which is held on by the tie wrap that holds the mouthpiece to the regulator. It must be up close to the neck in order to minimize the
venturi effect on the reg, and to provide a strap to hold that reg tightly in the mouth when necessary"

Correct me if am am wrong (please do)but isnt what george says above , slightly contradictary. He says that the bungee or surgical tubing is attached to the same tie wrap that secures the mouthpiece to the reg. Then he go's on to say that the neklace must be high up the regs neck to redice the venturi effect (freeflow). Wouldnt it be better to use a seperate tie wrap which can secure your neclace "higher" up the reg and thus allow it to hang in a way which reduces the chance of a freeflow.
On this thread i am trying to get some ideas on how to tie my bungee neclace to my backup reg. I have seen many ways of doing this:
Tuck bungee necklace under same tie wrap used to attach mouth piece. Or use a different tie wrap to attach the necklace higher up the regs neck (which would IMO reduce the venturi effect and thus better preventfreeflows).
Same as above but tie knots in the bungee, behind the tie wrap so that if someone pulls the reg it will stay attached to reg.
Or you can use silicone tubing to do the same as above although i personally found that the tubing comes away from the tie wrap to easily and you are left with a reg that is no longer around your neck and must be secured before the dive is continued.
On the other hand, if you are using a necklace with knots tied behind the tie wrap, and someone pulls hard enough then you are left with a reg which no longer has a mouthpiece attached. In addition this mouthpiece may well be lost and then you either end the dive or repair it underwater (assuming you carry a spare mouthpice and tie wrap on every dive!).
I thought that the best way to secure the reg is to use bungee cord. Tie 2 slip knots so that you can tighten the cord around the mouthpiece. Using this, the reg will come free if pulled and can be put back afterwards. This way you wont loose your mouthpiece and you dont have to worry about re-attaching your necklace with a tie wrap. I only thought of doing this earlier on today so i havnt actually got round to it yet.
What method do you use? Do you see any problems with either method described above, or perhaps you think the way that i outlined lastly, may cause problems. Opinions opinions and more opinions please, flame at will. Im looking forward to what you guys have to say. Cheers
