I have 17 pounds on my weightbelt right now. It's one more thing, and dropping 16 pounds is not an option nor necessary when you have a pony with enough gas in it to do a safe ascent including a 3 minute stop at 15 feet. > >The belt gives you a built in failure indicator< if you are paying attnetion >you can feel it slip, and thats easy to correct on your own> and if its >under you crotch stap has a built in anti ditch safety.

That evey agency has blow and go as >its last resort for ndl diving? Every dive is a deco dive, right? I think that after doing a dive to 130 feet, even if within NDL, my chances of getting bent on a blow and go ascent are pretty good. The NDL (well, my computers profile, I should say), are based on an ascent rate of 30 fpm. Going up like a bat out of hell isn't a good thing, isn't safe, and isn't necessary with a redundant gas supply. > >worried about buckle failure? wear two. So now I should wear a crotch strap, a weight belt, two buckles, just so I can drop 16 pounds and either embolize or get the bends ?!?!??!

Blow and go is not safe, and I do solo dives to 140 fsw. A pony is enough to get me back to the surface safely from that depth should I have a complete failure on the other tank. Last night I was readying and account by R. Pyle, and it occurred to me that you don't even need a big failure. All you need is for your pressure gauge needle to get stuck!!! >You dont need a pony bottle unless you are solo diving without a plan. The Pony has several advantages. One is that it's a redundant gas supply. Two is that you can put in a nitrox mix that give you a 1.6 on your max depth, figuring that there isn't even enough gas in the pony to make that a problem, but you have the option of switching to it at the safety stop for a higher percentage of O2 at that time. I will graduate to doubles eventually, but you can't take doubles with you easily when you travel. Doing deep dives within NDL's I don't see why a pony is so bad. I wear mine as a stage bottle, so it's good practice. If anyone bitches about your bringing too much gear, I would tell them to lick it, stamp it and mail it! It's your dive, your life, your safety, you decide!
