Ok I am trying to walk the straight and narrow and am starting off my quest by rigging my backup on a necklace. I have been looking at Harold and Patricks web site and am trying to idenitify the type of Knot used in attaching the ends of the necklace together into a slip to tie off around the Reg. Heres the Pic

Harold said he bought the rig at Brownies Third lung and wasnt sure. any ideas the pic isn't quite clear enough for me to tell. I tried a couple of clove hitches and it will prob work but not nearly as neat as the pic.

thanks

Sorry Aqua the pic didnt come out can only see the top 3/4inch but I think I know what you mean with a twist tie around the reg and the two ends secured to the tie.

BTW If you havent read any of it yet Harold and Patricks stories in the Library are great. Patricks log of his DIR 1 course makes you feel like you were there. Good stuff link is above in the first post
 
If I may, I would like to ask a "dumb" question. I know, I know, the only dumb question is the one that isn't asked.

I have been reading quite a bit here on the forum and I keep reading about divers attaching their back-up reg around their neck. Now here is my question, actually two, I guess. Is this a back-up reg in case of primary reg failure? or is this the octo reg that is used in case someone needs air.

Now the reason for the second part of the question. If there is an OOA situation, why would someone give up their primary reg and use their octo instead of being ready with the octo to give to the OOA diver and continue using their own primary? It would seem to me, having the octo in my hand ready to hand off and keeping the primary myself would be a faster way of getting air to the OOA diver then handing off the primary and then finding and using the octo.

As you can probably tell by the question, I am a fairly new diver and we did practice buddy breathing during our pool and OW dives. So it isn't like I don't know how to do this.

Anyway, any help you can give me on answering my question would be greatly appreciated.

Thank you.

Never be afraid to ask, never feel like a newbie, we are all students.

The concept is that one donates the reg out of ones own mouth, and then switches to the necklaced reg once the buddy is safe.

This ensures the buddy in the OOA situation has the best reg in the area (must be good, you were JUST using it!)

That is also the main reg is on a long hose, so the buddy can now have a bit of room, (we also use them in wrecks and caves so the buddy can swim ahead or behind you through tight restrictions)

The first is if you are diving doubles the valve on one side can be rolled off as the valve contacts the roof of an overhead. The idea is you hand off the primary because it comes from the valve that is facing in a way that can not roll off and you know you are handing the OOA diver a working reg. You can then turn your own air back on if it has rolled off. The reason for the bungee is it keeps your back up in a place where it can't be dangling in the mud, etc. and it is easy to find. People dive it this way with a single mainly in order to keep everything the same so you are always diving with the same set up.

The other is that if a diver is out of air they are likely to go for the reg they see bubbles coming out of and know is working. If you have the bungee set up you can find your back up easier right under your neck.

Hope that explains things.

Dive safe.

Cherry once bubbled...
I have been looking at Harold and Patricks web site and am trying to idenitify the type of Knot used...

Cherry, I think you're looking for what is often called a fisherman's knot.

You make it with a little more space in between the knot ends so that you can fit the mouthpiece through. Then pull tight just like in the diagram.

Have fun!
 
This is what I use - not DIR approved - for me, better.

Breathing The Long Hose

Despite its growing popularity, many divers remain opposed to donating the regulator from their mouth. The following discussion reviews the most common resistance to donating the long hose from the mouth.

The last thing I want to do in an out of air situation is give up my primary regulator.

This concern does not really seem to be a rational fear. It is likely that a diver incapable of removing the regulator from his or her mouth for five to ten seconds is not skilled or practiced enough to be in an overhead environment. One may question this divers ability handle an out of air situation in which the out of air diver chooses the regulator in their mouth despite their best intentions. A diver with this degree of concern over the regulator in their mouth may find it quite a challenge to even deal with the very real possibility of an accidentally dislodged regulator.

By donating the long hose regulator from the mouth in an out of air situation one guarantees that the person most in need of a clean fully functioning regulator is going to get it. If you pass any other regulator to an out of air diver it is possible that the regulator received may contain contaminants that will be impossible for the stressed diver to manage. In essence, what you will have done is to place the last straw on the camel's back, creating the last problem your dive buddy can manage. The advantage of donating your long hose primary is that you are always ready for this very real possibility. You are, in essence, always prepared for any eventuality rather than maintaining a fixed picture of how things should operate. Emergencies have an annoying habit of not going as planned and the Hogarthian system strives to remain prepared to manage a variety of out of air scenarios.

I don't want to breathe my long hose , I want to have the best performance regulator in my mouth and the long hose decreases this performance.

With literally thousands of deep exploration dives accomplished by divers breathing the long hose, the performance argument seems rather a moot point. Yet, if one were to insist that the reduction of performance is unmanageable, it seems like a poor solution to leave the stressed, out of air diver gasping for air on this lower performance regulator so you can have a more relaxed dive. Your best performance regulator must be on your long hose and if its performance is unacceptable in a relaxed situation then it is certainly inappropriate to suggest that the your stressed dive buddy is better prepared for this increased resistance. The one thing to be clear on is that if the regulator you try to provide to an out of air diver is in any way substandard, you will be giving up the regulator in your mouth and your ability to handle that situation may make the all the difference.

I just don't want to deal with that hose on the second stage in my mouth.

Any skill worth learning usually takes refinement. The long hose may at times seem uncomfortable to some people, but regardless of your storage location, you have to deal with that hose. When you tuck a long hose into some surgical tubing you feel that it is forgotten and indeed for some it is, but what happens when it pulls free or is not set just right? If you rely on your buddy to arrange this hose for you, what guarantee do you have that it is to your liking or even correctly placed? In a sport that preaches self-sufficiency, does it seem logical to configure your equipment in a way that forces dependence on your dive buddy?
