You look at your friend's granddaughter's new "Sea Fun Barbie" and note the orca, and the sea turtle, and the inflatable zodiac boat. Then you look at Barbie and her mask with attached snorkle, fins, and twin tanks with manifold; and start debating with your wife exactly what kind of diver Barbie is.
"Barbie dives with well streamlined gear - no dangling console."
"She's so streamlined, she does not even have regs!"
"Think there's a backplate and wing under those twin tanks?"
"They must be steel twins, she does not have a weight belt."
