"If self preservation is an instinct you posess..."Uncle Pug:OK Peter... what is your one reason.
Uncle Pug:No problem... take your time... thinking is good.
IF you have a so called *rapid depressurization from a leak in your hp hose*freborg:I was a passenger on a private boat where an experienced diver had a rapid depressurization from a leak in their hp hose. Had to ditch and make emergency ascent. I think I will stick with my pony.
Uncle Pug:IF you have a so called *rapid depressurization from a leak in your hp hose*
1. How rapid would that depressurization actually be given the very small orifice at the regulator end of the hose that prevents rapid depressurization... oooops... I gave that one away.
2. How deep would you be with 90% of your gas left and how long would you have to make a controlled ascent?
3. How deep would you be with 20% of your gas left and how long would you have to make a controlled ascent?
4. Would you ever be deeper than you could make a controlled ascent with only 20% of your gas left?
5. Why would you need to ditch your rig and make an emergency ascent?
You Peter, like many, are making the assumption that your pony will protect you from poor decision making. It won't.

BTW... I do carry a redundant *air* source and on recreational dives and it is right in there with the rest of my back gas... I know its there because I can see it with my SPG.
And my questions that you answered with a different scenario than the one originally put forward still make the point. A blown hp hose does not empty the tank and preclude a slow controlled ascent. The thoughtful response would be neither to dump the weights nor grab the pony but to inform your buddy of the situation and make a controlled ascent using the back gas available.DA Aquamaster:Correct me if I misunderstand, but I think the heart of your argument is that a pony will induce a false sense of security and confidence that will cause the diver to do something stupid. I agree that a pony is a not a cure for stupidity and that being stupid with a pony is almost as likely to get you dead as being stupid without a pony. But that does not mean that all divers who use ponies must be stupid.
Which is exactly the point Pug is making - by never touching the thing, you're just fooling yourself. You've got a security blanket that, when needed, you haven't practiced deploying, you don't know if it's working, etc. etc. etc.freborg:Pug
What I am assuming is that I will ride that pony my whole dive career and never take a breath.
