I took out the Track IR 5, which had been sealed for a long time. Since the passive reflector was broken, I could only stick it on the hat with tape. One thing that 2020 does is very user-friendly, that is, during track use, you can use the right mouse button to activate the free view without being affected by the track IR head position. If possible, I will use the active reflector for head aiming flight, which is very effective in treating cervical spondylosis.
