Bicycle pump air tanks.

You asked and you do not like the answers. I would mind to my own business and just as in this "conversation" you have jumped to insulting imagine how the other might go.

And you do seem to be getting worked up. Here, a comic just for you .



I do not think these units will have any effect on SCUBA accidents.

Yep clearly you need to go to bed. Good night little one!

So I have been seeing at ton of social media adds and posts for pony bottles that can be filled with a hand pump. Since you can order it online and pump it up at the water are we going to start seeing lots of scuba related injures? Also if you are out diving and you see someone trying to use one would you say something?

It takes an absurd amount of effort to pump these up by hand, and then they last for at most a couple minutes. I think many are 1.5 to 3 cubic feet. For reference, I believe I use about 100psi per breath on a 6cu at 8ft deep. On a 3cu, that would be 200psi. So, if you mange to get the bottle to 3000 psi, you've got 15 breaths or less.

I dove with a 3cu spare air at shallow depths once, and that was SUPER sketchy and was out of air WAY faster than I expected. A 6cu is probably the minimum size I'd say is any "fun" to use. Any smaller, it's barely any advantage over free-diving.

Will we see injuries? Maybe. It takes so much effort to pump up that people are unlikely to use one more than a couple times, before giving up.

Wow,
everyone is so touchy on scubaboard lately, Is it the heat or inflation?
Just go diving..

We are talking about pumps, so must be the inflation. But people did mention they get hot, so it could be the heat.

Talking your advice, diving in three days.....

No, it's the trolls

Stay away from bridges and you'll avoid most trolls

I also feel like this is all getting off topic from my original post on if this is going to increase scuba accidents and if you seen someone trying to use one would you speak up and off advice?

Interesting part is for in a helicopter we have them as a last ditch effort if you ended up under the water (the version is called a HEED3) and to get ours refilled at a shop I had to go to multiple shops as they refused to even fill it due to people using the tanks for diving and died apparently..

Realizing now that this thread was a troll, still, as a caution, I own both the bicycle high pressure pump and one of the electric pumps. They work quite well but are intended for PCP air rifles and that is my use when I cannot get a fill for my SCBA 4,500 psi tank. But it is highly likely they produce CO as they are not intended for breathing air and a PCP air rifle does not suffer from CO poisoning.

Inside of PCP rifle:



Moisture is the enemy of these rifles and moisture filters/traps are in place but the lubricants and precautions for CO, not so sure.
