Helmet diving, or "Surface Supplied Diving", is making a come back! Proponents say it's easier and safer for amateurs to use helmets for shallow dives than scuba tanks (the old canvas full body suits are gone though). Tourist resorts throughout the Caribbean and the Bahamas offer helmet dives - no PADI certification needed.
It's a great way to take an underwater walk on the reef, and you can hold a conversation with your buddies while you're down!

"Hardhat" divers had it rough. Tough to see and work in that outfit and, heavy as the diving suit was, he still needed a huge lead weight on his chest to stay down. I can't figure out why all the guys in suits surrounding the diver but it must have been an important dive. If it had been me though I would have opted for a younger man at the wheel of my air pump (on the left of the photo).
I think I'd die of heart failure before I even got into the water!
