Scuba
What scuba has contributed to our conquest of the ocean is already enormous.
To professional students of the sea it is nearly as important an invention as the printing press, and to amateurs it has been no less liberating.
With the simpler but equally important devices of face-plate and fins, it has made diving one of the great participant sports of our generation, and one of the great sources of education.
Amateur divers have made underwater photography, once the specialty of a few highly trained specialists, a mass hobby.
They have discovered new species of marine life. They have probed the wrecked skeletons of ships that otherwise might have been lost to history.
But our weapons of exploration and discovery are still just partially successful. The knowledge they give us is intimate but not deep.
We still know almost nothing about most of the 140 million square miles of ocean that surround us, of the shape and history of the continents they conceal, of their immeasurable and untapped resources, of their relationship to life itself.
Perhaps some day we will. The sea gives up its secrets slowly.
The history of diving is largely the story of equipment. The introduction of face-mask, fins and snorkel in the '30's planted the divers' flag firmly in underwater territory.
Exposure suits added new dimensions of area and season. And finally the demand-regulator lung took thousands of divers to depths that until then had been the exclusive province of men with hard hats and air lines.
But scuba has not made the mask-fin-snorkel combination obsolete.
If there's one opinion that all diving experts share, it's that nobody should simply strap on scuba and plunge, with no previous underwater experience.
Scuba should not provide anyone with his first look at the world under the surface. Before you bet your life on your ability to handle a lung, you should become a competent skin-diver—with mask, fins and snorkel as your only gear.
This is no mere dull preliminary chore. Actually, many of the top divers, hunters and photographers prefer to use the basic trio and rarely or never use lungs.
Besides, you can do things with just a mask that simply aren't possible with scuba.
