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.
Can you scuba dive to 500 feet?
This pressure, known as “storage depth,” is typically too deep to dive using air, so the divers breathe a mix of helium and oxygen called heliox. Below 500 feet, heliox can cause high-pressure nervous syndrome (HPNS), which is characterized by tremors.
Can you scuba dive 200 feet?
A diver who descends 200 feet beneath the surface of the water breathing air from a scuba tank is taking a big risk. Safety regulations for recreational divers limit them to 130 feet. Even specially trained scientific divers are required to stay above 190 feet or they lose their certification.
