The GPX North Seeking Gyro Station uses the popular SET X series total station and has wider range of angle accuracy than the previous model. The GPxX locates true north with two modes, follow-up measurement and time measurement, and determines North azimuth precision without any other aid. This gyro station is designed for mining, roads, railroads, power lines, pipelines, underground construction and other similar long and narrow projects. There are no restrictions by location, weather or time like other surveying solutions might have.Determine Azimuth Anywhere, Anytime
