I'm afraid you are on your own. They don't much teach that procedure.
My friend carries a pony bottle in his hand sometimes when he wants to make a short dive.
There would be a bit of a hazard to it in that you would still want to make fairly slow ascents.
Some standard size bottles are 6, 15 and 30 cubic feet. You could put a simple regulator on one that is in a bag and use that. To get to 70 feet, I would suggest at least a 15 foot tank.
You have a couple problems. Unless you add a pressure gauge, you could run into a surprise with a tank that wasn't quite full. In small tanks, that is critical. Also, at least one person has died when they dropped their tank.
It sounds like a good idea to use it like you say, but it is not standard and should be done carefully. If you were to use it to make a 70 foot dive, plan on a bit of a surface interval before aggressive freediving.
Enjoy the diving, seahunt
