Let’s take a look at each one of them.
The helmet in helmet diving is a unique type of diving helmet that allows divers to breathe underwater without wearing a traditional scuba tank.
Below are the types of helmets used in helmet diving:
- Open-circuit helmets provide fresh air from the surface compressor, releasing exhaled air into the water.
- Closed-circuit helmets recycle air that the diver is breathing, then remove CO2.
- Free-flow helmets are similar to open-circuit helmets.
- Lightweight helmets are more comfortable and less bulky than traditional helmets. They are made of plastic or carbon fiber.
Here are some of the structures and components that you might find in a helmet used for helmet diving:
- Faceplate – This is the clear window in the front of the helmet that allows the diver to see underwater. It is usually made of high-quality tempered glass that can withstand diving pressure.
- Air supply – The helmet is connected to an air supply that provides a continuous flow of air for the diver to breathe. The air supply may come from a compressor on the surface.
- Exhaust system – As the diver breathes in the helmet, carbon dioxide builds up, so there needs to be a way for it to escape. The exhaust system allows carbon dioxide to be released from the helmet.
- Neck dam – The neck dam is a flexible seal that helps to keep water out of the helmet. It fits snugly around the neck of the diver, creating a watertight seal.
- Allows for normal breathing. You don’t need a compressed air tank on your back or a regulator in your mouth.
- It provides a clear, unobstructed view of the underwater environment.
- It makes it easier to communicate with other divers.
- The helmet can be heavy, making it more challenging to move around underwater.
- The helmet limits head and neck movement, making it harder to explore.
