Take a look at the movie Deep Blue Sea, the shark wrangler uses the Spare air 3cf tank to trick the shark...
He places his BCD with tank on the cage with a small stream of bubbles while the shark goes for it thinking he has a meal, the shark wrangler appears above the shark and shoots a dart to tranquilize the beast...
All while on 3 cf Spare air, it's a sight to see, wonder how much the company paid for him to use it on the scene?
So we do have a use for Spare air, trick a shark and dart him....
They used them all the time on BayWatch also... and we all know how fake that show was...
