Product Description
CHCNav MCNAV TX73 is designed for demanding construction sites. The system gives operators full control of depth, slope, and alignment using advanced GNSS RTK receivers and IMU sensors. With instant bucket-tip feedback and real-time surface comparison, jobs finish faster, cleaner, and with fewer grade checks.
The TX73’s powerful CAD-based 3D interface and color-coded maps let crews visualize progress directly in-cab. Operators can customize layouts, monitor cut/fill data, and switch effortlessly between 2D and 3D views. With broad attachment compatibility—including Engcon and Steelwrist tiltrotators—the TX73 adapts easily to complex projects. Its rugged hardware—featuring the MC300 receiver, IS300 IMU, and AT315 GNSS antennas—ensures reliability in harsh environments.
