The Ultimate scuba Tank

He has a BC tied to the end of it.

That tank is 300 cu/ft.

While it does look like my 300 cf storage bottles, it was either underfilled or is very low pressure. It says it is a 50 liter tank filled to 100 bar, which is 5000 liters or about 175 cubic feet. If we assume that it is rated for 150 bar or 2250 psi like my LP storage bottles, then at full capacity it would be about 265 cf.

I also believe it involved Photoshopping. My storage tanks are so damn heavy they would require at least 100 pounds of lift to be neutral.

He also says the buoyancy of it was so great that he had to remove the BC at the bottom.

It is probably a 244, they do look about the same but the 244 is considerably lighter. The down side is you would have to knock off about an hour of bottom time. I will stick with my method, putting 3 300s together, leave them on the surface and dive off an umbilical.

Don't know what the buoyancy specs of that tank are, but you would breathe the same amount of gas on a given dive no matter how big a tank you were connected to (leaving aside whatever extra gas you would burn due to the work of hauling that thing around).

Right... but presumably if you use the entire tank you will be underwater much much much longer, and that would create quite the swing in buoyancy. Of course air in one tank weighs the same as air in another.

Don't see the point. When I'm diving here in the cold, not so clear water I have no reason to spend huge amounts of time deep. I don't do wrecks so what I dive for is mostly shallow. I use either a 50cf or a 27cf and get about 45 min and 30 min respectively. Diving warm water I get unlimited air and dive as many 80 cf tanks as I want. I see no point in the awkward single enourmous tank compared to doubles. Seems like someone looking for attention.

I guess "humor" is missed by you.... No, not really "funny", but it does earn a "dooh"...

at least it isn't some abomination cluster of Spare Air cylinders...
