A 3 cubic ft tank couldn't get me to 70', i'd eat it in the first minute.

That's why you carry two.

This one looks really happy, and it's already wearing it's shorty wetsuit and is ready to don dive gear and explore the Hydroatlantic!

A blue haired troll with a striped background? Everyone knows that Hamburglar prefers stripes...

How about a blue haired troll wearing striped Speedos?

Assuming that the intention was to provoke a serious discussion...

It is obvious that a spare air is not going to get you very far off the deck at 150 feet, especially if you have any intention of doing deep stops. You could get what you can from it and then get to 70 feet with a CESA, the whole time deploying your 50% bottle so you can start breathing it right away.

Of course, I don't recommend that as a dive plan.

In the end, I think that careful gas management and safe diving practices should be really stressed. It occurs to me that people need to be aware of the fact that they are going to run into trouble and should be ready for it. Unclipping a bottle and handing it off in an out of air emergency should be frowned upon; You are OUT OF ****ING AIR.

Anyways, here's some numbers from a 70' skills dive in **** tons of current:

You need to take into account whether this is an average SAC while doing moderate work, at rest/deco or SAC under stress/panic as part of your gas planning.

That was doing un-planned valve drills at ~100'. I seem to recall this:

Tas and Worm diving in the sea
Lesley works us like little worker bees
Floating patiently, silently, stalking us.
HISSSSSS BUBBBLE BUBBLE BUBBLE WHAT THE F***!!!!!!!!!!!!!!

I'm sure some others will know what I mean.....

Can you expand on why you feel this is a bad idea?

That's not a warning. I just thought you'd appreciate that pic, somewhat combining your recent pics and avatar together.
