15 Scuba Diving Facts

15 epic scuba diving facts your hooked-on-diving-brain has been craving.

1. SCUBA is an acronym

It’s a fact: you NEED to try SCUBA.

SCUBA is full of acronyms. In fact, SCUBA itself IS an acronym. It means:

  • Self
  • Contained
  • Underwater
  • Breathing
  • Apparatus

2. Jacques Cousteau invented the first Aqua Lung

Today, Aqua Lung is a popular brand of dive gear (my favorite!) However, before it was a gear brand, it was the first breathing apparatus that worked on demand. Meaning, the regulator wasn’t continuously spewing out air from the scuba tank (not good if you wanted to stay below the surface for any amount of time).

If you aren’t familiar with Jacques Cousteau, well, he was sort of a badass with a lot of good work continuing in his name today.

3. Earth is mostly water

Much of it is yet to be explored!

71% to be exact – which leaves you and me PLENTY of area to explore while scuba diving!

4. The ocean is the last frontier

The ocean is the last frontier on our planet.

Of that 71%, a large chunk of it is ocean. And of that large chunk of ocean, 80% is unexplored. How awesome, right? The ocean is literally the last frontier – unexplored territory – on our planet. Scuba divers are on the forefront to discover what is yet to be known.

5. Scuba divers are limited by recreational limits

And part of the reason why so much of it is unexplored is because scuba divers are just a wee bit limited. In fact, recreationally, we’re capped at 130 feet below the surface. This is the depth deemed safe (although it requires a lot of training to get even this deep). Anything deeper? Even more equipment, extensive training and years of experience are required.

6. The world’s deepest scuba dive exceeded 1,000 feet

Which speaking of, a 41-year-old Egyptian gentleman named Ahmed Gabr set the world record for deepest scuba dive, plunging a mind-boggling 332.35 m (1,090 feet 4.5 in) in the Red Sea off the coast of Dahab, Egypt.

It took him 12 minutes to reach this depth and 15 hours to return to the surface.

7. Scuba divers explore all sorts of environments

Coral reefs, like Vista Park Reef in Fort Lauderdale, are our favorite types of dive sites.

No body of water is safe from a scuba diver. Common dive sites include shipwrecks, coral reefs, lakes, flooded mines, sunken cities, springs, cenotes and caves.

8. Water absorbs light

At 90 feet below the surface, the Mercedes Shipwreck in Fort Lauderdale lacks some serious color.

One of the first things new divers notice is the lack of color underwater. And that’s because water absorbs any sunlight piercing through the surface. But that’s not to say all is lost.

Now, think back to 6th grade science class and the spectrum of visible light. ROYGBIV sound familiar? It’s the colors of the rainbow! Duh!

As you descend underwater you begin to lose the colors of the spectrum. Red goes first. Orange second. Yellow third. And so on. Around 400 feet almost all light is gone.

That’s why divers bring underwater cameras (including GoPro) with attached filters to accommodate the lack of light. Take a photo or video and voila! Your video now has all the color that was missing underwater!

9. Sound travels 5x faster underwater

Using a dive flag on a dive at Blue Heron Bridge in West Palm Beach just in case we hear a boat approaching underwater.

Ever been diving and it sounds like that boat on the surface is approaching fast? Like very fast? Well first of all, it probably is – better stay low. But another part of the reason is sound actually travels 5x faster underwater than it does air. Now, whether or not it travels farther is a difference story (see link above).

10. Sharks are friendly beasts

After the latest edition of Indiana Jones (Kingdom of the Crystal Skull), we all should have a bone to pick with Steven Spielberg. However, my original gripes with the movie director was from long ago in the 1975 film, Jaws. Ever since, sharks have been unfairly characterized and maligned (thanks a lot, Steven).

Truth is, sharks are gentle giants and RARELY, and I mean RARELY bite humans (57 unprovoked attacks worldwide in 2020). In fact, you’re more likely to get bitten by a human in New York City than a shark in the world.

Still not convinced? Vending machines account for more deaths in the US than sharks worldwide. Other things that are more likely to kill you than sharks? Coconuts, champagne corks, driving and hot dogs. Just to name a few.

11. More plastic than fish will be in the ocean soon

Using alternatives to single-use plastic can have positive impacts on our ocean environments.

In a recent eye opening report, it’s estimated that by year 2050, the ocean will contain more plastic than fish. A devastating prediction that should scare the bejeezus out of anyone. But what can be done?

It’s a daunting task to solve but one that starts at home. Here is an article we wrote detailing all the ways you can help reduce your plastic use. In fact, scuba divers are at the forefront of this crisis – we’re the frontline defense!

And thankfully, many companies are joining the fight to remove as much plastic as they can from our oceans. Let’s work together!

12. Invasive Species are a huge threat

A seldom thought of problem our oceans are facing is threats from invasive species. In the Western Atlantic, in particular, lionfish are kicking ass and taking names. Meaning, they are absolutely destroying the coral reefs in Florida, The Bahamas, Caribbean, Gulf of Mexico and beyond.

What’s the solution? For a species as evasive as lionfish, scuba divers hunting them is the best means of removal!

It’s an intimidating thing to get involved in, and that’s why we’re here to provide you with all the information to get started hunting!

13. SCUBA requires a lot of gear

Double check you have everything with our dive gear checklist.

Part of the reason scuba diving is so intimidating to get involved with is the sheer amount of equipment involved. Large tanks, winding hoses, inflatable vests, gizmos and gadgets. Where do you even start?

We’ve simplified scuba gear to make it much less intimidating for the beginner (or advanced) diver. Check out our list for best scuba gear for beginners. If you’re a little more experienced, than don’t forget these 23+ items on your dive gear checklist.

14. SCUBA requires a lot of training

To become scuba certified you need to participate in a variety of classroom sessions, online learning, pool training, and open water dives. It’s no simple task.

Even past that, you’ll want to elevate your dive game with advanced certifications, wreck diving, enriched air and so on. The education and the training seems limitless. However, it’s an adventure of a lifetime and one that will open SO many neat opportunities for you.

15. Divers are avid travelers

Divers love to travel far and wide.

Epic dives spread far and wide across the globe. So naturally, scuba divers are avid travelers – many of which dedicate their lives to seeing pristine coral reefs, ghostly shipwrecks or rare marine life. The list of places to see and explore is endless.
