What is the purpose of the umbilical hose in the MK-20 system?

The umbilical hose in the MK-20 system serves an essential dual role by providing both breathing gas and communication capabilities between the diver and the surface support team. This is crucial for ensuring the safety and effectiveness of a dive operation.

The breathing gas is supplied through the umbilical hose, allowing divers to receive a continuous flow of air or other gases necessary for underwater respiration. This connection enables safe and extended underwater operations without relying on tanks strapped to the diver’s back.

Simultaneously, the umbilical hose facilitates communication. It incorporates a communications line that allows the diver to maintain contact with surface personnel, ensuring that any issues can be quickly addressed and that the diver can receive instructions or guidance during the dive.

This integrated functionality enhances both operational safety and efficiency, making it a fundamental component of the MK-20 system.
