What is considered the safest depth for a freediver?
Meeting – The objective is for the safety diver to meet the freediver and escort him- Face to Face through the area of greatest danger – which is between 15m and the surface. The depth at which they meet should be relative to the depth that the freediver has dived but not deeper than 15m.
How can freedivers go so deep?
So how is it that freedivers are able to dive so deep and last so long without taking a breath? One reason is the diving reflex, an evolutionary adaptation that enables seals and dolphins to dive deep and stay underwater for extended periods by slowing and/or shutting down some physiological functions.
How deep can a beginner freediver go?

Can divers go down to the Titanic?
You cannot scuba dive to the Titanic due to its depth at 12,500 feet. Air consumption: one standard tank lasts 15 minutes at 120 feet. Supply for 12,500 feet would be impossible to carry even with a team. The deepest dive on record with special equipment, training and a support team is 1,100 feet.
What is the deepest dive ever made?
The deepest dive on record is 1,082 feet (332 meters) set by Ahmed Gabr in 2014. That depth is the equivalent to approximately 10 NBA basketball courts aligned vertically. In terms of pressure, that’s about 485 pounds per square inch. Most people’s lungs would be crushed at that depth.
What happens to a human body at crush depth?
Since your body’s internal pressure is so much less than the ambient pressure, your lungs would not have the strength to push back against the water pressure. At a deep enough level, the lungs would collapse completely, killing you instantly.
At what depth do you start sinking?
As you start to descend, the pressure of the water pushes you back towards the surface, until around 13m to 20m deep when the dynamic is reversed. Here, according to Amati: Your body begins to sink a little bit like a stone.
