# FAQ: How deep can divers go?

## How deep can a human dive before being crushed?

Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.

## What is the maximum depth a diver can go?

With basic open water certification, a diver can dive to a maximum depth of 18 meters (around 60 feet ). With further training, you can obtain the Advanced Open Water diving certification that will allow you to dive to a depth of 30 meters (around 100 feet).

## How deep can you dive without decompression?

The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres ( 130 ft ), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.

## Which is the deepest diver?

253.2 Metres Deep Known as the deepest man on Earth, Herbert Nitsch is the current freediving world record champion with a world record dive in 2012 at 253.2 meters (831 feet).

## Can a human dive to the Titanic?

No, you cannot scuba dive to the Titanic. The Titanic lies in 12,500 feet of ice cold Atlantic ocean and the maximum depth a human can scuba dive is between 400 to 1000 feet because of water pressure.

## At what depth will water crush you?

At about 10–12 meters (33–40 feet) of depth, pressure of water column above you (1 extra atmosphere of pressure per 10 meters) will compress air spaces in your body by half, with lungs compressing the most by the absolute volume.

## How deep do navy seals dive?

Navy SEALS commonly don’t need to be in extremely deep water for their work. But with how extensive their training is in diving, they are likely to be certified to dive 100- 130 feet or deeper with many technical certifications on top of that.

## Why do divers fall backwards into the sea?

Scuba divers fall off the boat backwards to protect their gear so as not to loose anything. The tank on the back breaks the water tension and since all other gear is on the sides or the front of the diver it all goes in more smoothly.

## Can you survive 47 meters underwater?

The Easy Explanation: Nitrogen Narcosis Nitrogen or gas narcosis can happen at 47 meters down. It is actually quite common at depths beyond 30 meters, and can be more severe at greater depths. This is why most diving agencies will have a recommend recreational depth limit of 40 meters.

## At what depth does the bends start?

The Bends /DCS in very simple terms Anyone who dives deeper than 10 metres (30ft.) while breathing air from a scuba tank is affecting the balance of gases inside the tissues of their body. The deeper you dive, the greater the effect.

## Can you get the bends in 10 feet of water?

About 40 percent of the bent divers made a single dive with only one ascent. The shallowest depth for a single dive producing bends symptoms was ten feet (three meters), with the bottom time unknown. However, most of the divers made several shallow dives and sometimes multiple ascents.

## What is a no stop dive?

A ” no -decompression”, or ” no – stop ” dive is a dive that needs no decompression stops during the ascent according to the chosen algorithm or tables, and relies on a controlled ascent rate for the elimination of excess inert gases. In effect, the diver is doing continuous decompression during the ascent.

## What is the deepest a person has free dived?

Freediving – free immersion/ free apnea (men) The deepest dive in the free immersion (FIM) discipline by a male freediver is 125 metres (410 ft 1…

## What is at the bottom of the ocean?

The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean, no matter how deep. All floors of the ocean are known as ‘seabeds’.

## What is the longest free dive time?

Free divers swim to extreme depths underwater (the current record is 214m) without any breathing apparatus. Champions can hold their breath for extraordinary amounts of time – the record for women is nine minutes, and men 11.
