DIR Necklace question

[DiverBuoy]

Ok so instead of the necklace, why not Air 2? - I still donate my primary, if I stick a 7 foot hose on the primary can I be in DIR compliance? The Air2 is within 8 inches of my mouth and on the short hose ()

No I don't have a BP with wings. I've got a SeaQuest Pro Unlimited Tech Buoyancy Compensator with special low back support structure - and I aint giving it up for nothing.

Er, in response to Aquamaniac's response to the question of length:

Use a seven foot primary for overhead diving. A five foot hose is adequate for open water. Also, the seven-footer is hard to secure without a canister light.

We teach our BP/Wing divers who don't own can lights to secure the 7-foot hose by routing it under the belt knife, which is kept just to the left of the buckle.

That said, a five-foot hose does work just fine for open water diving.

I do the same as Aquamaniac, but use latex surgical tubing instead. Works great.

Why do you use a bungee for your safe second instead of a rope or string or something of that sort? I recently got rid of my octo and am diving with two regular second stages and want to get the setup right the first time.
Thank you.

Well, since the experts aren't rushing to answer your question, here's my version:

The backup reg is secured with bungee, because your goal is for the backup to be right under your chin, and possibly close enough to mouth it without using your hands. The stretch of the bungee cord allows you to get the bungee over your head, and still keeps it close enough for deployment. If you used a string or rope, when you pull it over your head, the backup would hang way too low.

You can see the pics from the links earlier in this thread for reference on rigging your backup properly. Feel free to check back in with your own pics to confirm you've got it right.
