Scuba diving without certification is the cheapest way to feel like a superhero. You get to breathe where you shouldn’t be able to breathe. You get to float like a wobbly jellybean. You get to discover that the ocean is less scary and more goofy than you imagined.
So yes, book that “discover” dive. Ignore the certification purists. You’ll get certified later—maybe. Or maybe you’ll just do the fun part forever. The ocean doesn’t check your ID. It just waits, full of bubbles and gossipy fish.
