High performance, low cost
Digital Magnetic Compass (DMC) Prime
Prime is a full-featured 6-axis digital compass designed for flexibility and adaptability — the perfect fit for sonobuoys, ADCPs, side scan sonar, low-cost robotics, and other cost- sensitive applications.

Built on the field proven TCM platform, Prime provides pitch, provides pitch, roll, and compass heading everywhere, including where GPS is compromised or unavailable, such as underwater, underground, beneath bridges, or inside buildings.
Low-power-consumption, low-cost Prime provides all-digital compass heading outputs accurate to 1 degree.
ITAR-free and made in the U.S.A.
Can be calibrated to account for magnetic distortions, and it offers several user programmable parameters, including output damping, reporting units, and sampling configuration.
Prime supports RS232 output; Prime TTL modules have a straight pin connector and supports TTL output; Prime TTL-RA modules have a right-angle connector and supports TTL output.
