Abyss Scuba Diving

How Deep Can You Dive?


How Deep Can You Dive?

Diving deeper into the abyss is a long-held desire of many divers, as it allows them to see new and exciting things. Many people have a pool or a reef in their local area that they dive in regularly, but there is so much more to discover! For many, diving deep is the next step in their dive planning.

There are many things to consider when planning a deep dive, such as your experience level, the type of dive you want to do, and most importantly, your safety. When it comes to the question of how deep you can dive, it depends entirely on what type of diving you are doing, recreational scuba diving, decompression diving, mixed gas diving, freediving, or rebreather diving.

How Deep Can Recreational Divers Dive?

As an open water diver, you are certified to dive to a depth of eighteen meters in sea water. If you wish to dive a little deeper, advanced open water certification will train you to dive 30m. To scuba dive forty meters, the Deep Diver specialty certification is mandatory. Diving below 30 meters can lead to nitrogen narcosis, which is like being intoxicated underwater. While not dangerous itself, if not recognized or corrected, nitrogen narcosis can lead to diver error.

How Deep Can You Dive on Air?

When diving on standard air at or beyond forty meters, you are in the realm of hyperbaric saturation diving, and require decompression stops as you ascend. When diving on standard air we do not reach a threshold of danger that may result in the death of the diver at below 61 meters.

How Deep Can You Dive on Mixed Gases?

With various gas mixtures that include helium, the effects of narcosis, decompression sickness and oxygen toxicity are minimized. Although helium at depth presents the risk of high-pressure nervous syndrome which can bring about dizziness, muscle twitching, and fatigue and thus becomes one of the limiting factors of how deep you can dive.

The deepest scuba dive ever was 332 meters set in 2014. That depth which is twenty-three metres more than the height of Sydney’s famous icon, the famous Sydney Tower. In terms of pressure, that is about thirty-three atmospheres of pressure.

How Deep Can a Freediver Dive?

The most basic distinction between scuba diving and freediving is the way in which divers breathe. Scuba divers are taught never to hold their breath underwater, as this could lead to lung overexpansion. Free divers, conversely, hold their breath throughout the entire dive.

What is so remarkable about Freediving is that it allows freedivers to reach astonishing underwater depths without the aid of scuba-related technologies. Champions of freediving swim without any breathing apparatus to extraordinary depths, with the current record at 214 meters and the current champion holding their breath for eleven minutes.
