The servo type SMD compass has been reported by the authors before. This time, two pairs of SMD bridges are used, one being fixed fore and aft and the other transverse. Each output from the SMD bridge is given to the oscilloscope acting X-Y, and then the brilliant line showing the direction appears on the CRT. In this paper, theoretical and experimental investigations on the CRT presentation type SMD compass are reported.
