You didn't do a search did you...? :11: It's a dead horse subject.

What style mount do you use?
Nice post Bill, seems intuitively like that would work. I can tell you that I am never anywhere near whoever I am diving "with" and if I ran OOA, going lateral probably would not be my choice unless I had a breath first. And you are right, it's not "take a breath, and hold it" it's "no, sorry no air here" Having empty lungs even makes it a bit harder to swim to the surface I found. You don't really think about the being so negative part....
Somebody had tuned my air off...just so people don't think I am careless.
Now, Don, we love spare air debates around here, you know that....math tutorials and all.
I thought the idea of mounting the pony upside down sounded good, where you can see the first stage for a bubble check..

Redundant air supplies would probably be widely used if 13 -19CF tanks were supplied at resort locations. Just think, manufacturers could DOUBLE the number of regs sold if pony bottles were required! Personally, I would be thrilled to dive with redundant air without having to drag a tank through baggage and the TSA check.

Yes I did a search, The search engine seems to hit the words but not the sequence of words in priority. There were a lot of hits and I read through a few and didn't see what I wanted. And the reason this is a useful thread is for 3. reasons, 1. the next few questions I have from reading the replies, 2. the fact that my life may depend on it. 3. Maybe discussing something again may help someone who isn't as experienced or cause someone to review their existing situation.
Ok folks, a couple of questions for you.
I also "searched" trying to find the meaning of "slinging" a bottle, I also looked at different sites (for mounting) trying to find the best way for me to mount another small tank and couldnt find the meaning/hardware for slinging. I saw a D-ring strap that looked quick and easy.
In adding a pony, can't I remove weight from my BC, isn't it just a swap or am I adding positive bouyancy? For those of you that added a pony, what did you have to change trim / weight wise?
thanks for the help, sorry that I stirred up a "dead horse" and offended some.

Central Fla:
A bit of poking around and I found this link http://www.gue.com/Equipment/Config/index.html
It is about 3/4 of the way down the page, but there is a clear picture of a couple of bottles rigged for slinging. All throughout the same page are various pictures of divers carrying slung bottles underwater.

If you want to sling a bottle it will be easiest with a BP/Wings.

The 6CF bottle has been tested by reviewers from max recreational depths (130 feet) and according to the testers was more than enough to get you safely to the surface. It was not intended to allow for deco stops, get you out of a cave, allow you to reconfigure your entire system or anything else.
Yes, if everything goes exactly how you should have planned it then you should not need any spare air supplies, but when the SHTF I would rather have something than nothing.
For example, when my son-in-law had the joy of a partially opened valve (thanks to the dive crew who assumed it was closed then "opened" after we had already opened it) instead of breathing out, trying to get a breath. realizing the primary was not working, checking the backup, realizing that it was not working, then having to do a CESA with no air (it was his first dive ever after a resort course) because the DM who was supposed to be watching him left him to help another tourist, could have grabbed the 6CF bottle, breathed on it, swam the 30 feet to me and we could have shared air and figured out what was wrong.
For those of you who think he should have tried to figure out was was wrong, try a little experiment, breath out, then pull the reg from you mouth and see how long you can sit there with nothing but the dead air in your lungs. I had my primary jerked from my mouth once when I had just finished an exhale, believe me the seconds it took to get the secondary into my mouth where pretty long. (Of course then the secondary a combined fill/secondary breathed super wet and I couldn't get a complete breath with it..hence I have switched to a full performance secondary.)
ANyway, I believe the 6CF size is functional for what it was designed for, to get you to the surface safely in an OOA from recreational depths. I do question the value of 3CF units for anything but the most shallow of dives.
