Kirby Morgan® Air Control System 5 (KMACS-5) with Communications.
The Kirby Morgan® Air Control System 5 (KMACS 5) is a lightweight, portable control box for use in surface supplied air diving operations. The KMACS 5 controls the diver's air supply, communications and monitors the diver's depth. It allows two divers clear push-to-talk (two wire) or round robin (four wire) communications. The KMACS 5 is also available without communications.
The air supply can be either from a low pressure compressor or high-pressure cylinders.
