The commander’s main sight is a French SFIM VS 580-10 panoramic day sight that allows him to scan through a full 360 degrees without moving his head.

The gunner would then engage the target while the commander looked for the next target. Both the gunner's sight and commander's hunter-killer sight were 2-axis stabilized, had both direct vision and FLIR optics, and with the gunner's sight having access to a CO2 eye safe laser rangefinder made by Raytheon. Any crewmember could use the armament ...

The pilot/gunner had to look into the narrow field folded prismatic telescopic sight at the top of the device, a drawback corrected in the later Mark II. After tests with two experimental gyro gunsights which had begun in 1939, the first production gyro gunsight was the British Mark I Gyro Sight, developed at Farnborough in 1941.
