Understanding what is scuba diving before exploring the depths 

What is scuba diving? Scuba stands for Self-Contained Underwater Breathing Apparatus. When you scuba dive, you wear special gear and breathe underwater for extended periods. What is scuba diving like? Imagine swimming through a coral reef or exploring a shipwreck or all the other amazing sea creatures deep down underwater for longer times. That is what scuba diving is like. You can explore underwater just like a fish with the help of SCUBA equipment.

A history of breathing underwater

Scuba diving is not a new thing. It actually dates back to the early 1900s. The pioneers of these amazing gadgets were Jacques Cousteau and Émile Gagnan. They invented the device called Aqua-Lung. It was the first modern open-circuit scuba system. With this groundbreaking invention, divers could carry their own air supply. Thanks to it, they can explore underwater for longer without needing air from the surface.

From military to mainstream

At first, scuba diving was mostly used for military and scientific purposes. However, it became a popular recreational activity for adventurers and ocean lovers over time. Today, every adult from any background can enjoy scuba diving!

New tech brings along new adventures

Scuba diving progresses rapidly thanks to new technology. Here are some exciting advancements added to scuba diving to enjoy it even more.

Eco-diving – Divers are becoming more aware of protecting the ocean. They’re diving in protected areas and even helping scientists study marine life.
Underwater drones – These little robots can explore tight underwater spaces and send amazing footage back to the divers.
Virtual reality diving – Want to feel like you’re swimming with whales? VR can make diving even more immersive for you.
Smart dive computers – These gadgets are developed to keep divers safe. They can track divers’ depth, air supply, and even their decompression sickness risk.

Is scuba diving a sport?

Yes! It is a sport because scuba divers get physically fit and learn proper techniques while scuba diving. There is even a competitive side to it with events like underwater photo contests and diving competitions. However, it can also be a recreational hobby because, most of the time, what you do while scuba diving is exploring and having fun in the water.

What are the different types of diving?

There are several different types of diving. Let’s explore some of them.

Free diving

This is the most old-school way of diving. When free diving, you hold your breath and explore underwater without any scuba equipment. You need to practice a lot to hold your breath for long periods.

Drift diving

In drift diving, you basically go with the current flow (like a river or ocean current) instead of having a planned route. It is like going for a relaxing underwater float trip. The current could be an ocean current, tidal current, or the natural course of a river. It depends on where you are diving.

Deep diving

Just like the name says, you can dive much deeper than usual recreational dives when you deep dive. And you can explore areas most divers do not get to see.

Wreck Diving

Have you ever wanted to visit an underwater museum? With wreck diving, you can explore shipwrecks, airplanes, and other sunken structures underwater. It is like diving through history.

Cave and Cavern Diving

This adventure takes you into underwater caves and caverns. It is an incredible diving experience, but you need to get special training first because it can be risky.

Night Diving

The underwater world does not sleep. With night diving, you can see the ocean in a whole new light, dive light. Why night diving? So many different creatures come out at night.

Technical Diving

Are you an experienced diver? Do you want to push the limits? Then technical diving is perfect for you. Here, you can go deeper, stay down longer, and sometimes, you can even enter underwater caves or tunnels. You will usually need extra training and special equipment for technical diving.

Difference between snorkeling vs scuba diving

Both snorkeling and scuba diving are great water activities to explore underwater, but they offer different experiences. Now that you  understand what is scuba diving, let’s explore other famous recreational activities and see how they differ from each other.

Snorkeling is an easy way to explore sea

What is snorkeling? Imagine swimming on the water’s surface and peering down into a crystal-clear world. This is snorkeling. You just need a mask, fins, and a snorkel to get started. Once you dive in, you can observe colorful fish, coral reefs, and other underwater wonders from the surface. Snorkeling is perfect for beginners because,

It is easy to learn, and you need way less equipment.
You can comfortably stay close to the surface without any risks.
You do not have any training at all. Even nonswimmers can snorkel.

However, snorkeling equipment limits you to the top few meters of water. So, you will not be able to see deep into the ocean.

Scuba diving for deep sea exploration

Scuba diving is like strapping on a personal breathing apparatus and venturing into the deep sea. But before you diving in, you must wear a scuba tank, a regulator, and a buoyancy control device (BCD) to help you stay afloat. Scuba diving offers an amazing experience because,

You can explore coral reefs, shipwrecks, and any kind of marine life up close.
You can dive deeper underwater and stay longer.
It is your opportunity to connect with the ocean in a whole new way.

But compared to snorkeling, you need following when you scuba dive,

More training and certification to ensure safety.
More specialized equipment.
Higher commitment in time and cost.

Get started with scuba diving

Are you ready to dive in and explore what lies beneath the waves? But before you jump in, you need to know a few things.

How to do scuba diving? Let us learn ropes.

Scuba diving is not all just swimming with the fish. Your safety is very important. So, your first step to scuba diving is education. You need to enroll in a scuba diving for beginners certification course, like the Open Water Diver Course, to begin your scuba diving journey. In this course, you will learn the basics of scuba diving, such as,

How to use your equipment
Manage your air supply
Understand how things work underwater, like pressure, temperature
How light and sound behave differently underwater
How to stay safe underwater.

Practice in confined water dives

After learning the theory, you will practice your scuba skills in a pool or calm, shallow water. Here, you will learn how to assemble your scuba gear, clear water from your mask, and comfortably move underwater.

Open water exploration

Once you are comfortable and confident, you will head to open water, like an ocean or lake. You will take four dives, usually over two days. Here, you can use all the skills you learned while exploring underwater.

Who can scuba dive?

Scuba diving is actually open to more people than you might think. As long as you’re 8 years old or older and comfortable in the water, you can give it a try. Even people with physical difficulties can learn to scuba dive using adaptive techniques. So, don’t be discouraged if you have challenges; many people with paraplegia or amputations have become certified divers.

How old do you have to be to scuba dive? As we said, young kids from eight can participate in introductory scuba programs. At 10, they can take the first step towards certification with a PADI Junior Open Water Diver course. Once certified, Junior Open Water Divers, ages 10 and 11, can dive with a parent, a guardian, or a PADI Pro as their buddy.
