The CompassPoint family of cost-effective, low-power consumption compasses harnesses the existing power of Earth's magnetic field to measure orientation in 2 or 3 dimensions. All CompassPoint modules incorporate PNI's magnetic distortion correction to ensure accurate heading measurements when installed in the host system. And because they typically use 2 to 3 times less power than comparable sensor modules, they're perfect for applications in which power sources are few and far between. CompassPoint modules represent exceptional values and are ideal components for cost-sensitive products that historically could not justify such well-featured digital compasses, such as laser range finders, sonobuoys, wind sensing equipment, and acoustic Doppler current profilers (ADCPs).
