OWL-UD is a helmet-mounted, compact and ruggedized display unit. Being used in combination with universal thermal tactical sight or our OWL-M sight series, it serves as a secondary display unit, enabling users to see images obtained from the sight without being straight in the line of fire.
OWL-UD can be adjusted to connect to various sight devices with external video output.
