The new TargetPoint TCM gyro-stabilized digital magnetic compass – Accurate heading in any environment

TargetPoint TCM incorporates magnetometers, accelerometers and gyroscopes for unmatched performance in real-world conditions. It combines PNI’s high sensitivity Magneto-Inductive sensors with the latest high stability 3-axis MEMS accelerometer and 3-axis MEMS gyroscopes providing accurate orientation while in motion and in magnetically challenging environments. TargetPoint TCM excels in conditions that cause errors in traditional digital magnetic compasses.

TargetPoint TCM uses advanced magnetic distortion compensation and calibration scoring algorithms to counter the effects of hard and soft iron interference, providing highly accurate heading information in almost any environment and orientation.


  • Patented magnetic anomaly rejection algorithms eliminate errors due to magnetic distortion, even in magnetically harsh environments
  • Gyro-stabilized compass for dynamic accuracy of sub-0.5 degrees of heading accuracy
  • Multiple calibration methods are available to ensure ease of calibration for all applications
  • ITAR-free
