Reliable Electronic Angle Measurement

The ET-02 is designed for surveyors who need dependable electronic angle measurement without the additional complexity of a total station. Its absolute encoder automatically indexes the horizontal and vertical circles when the instrument is powered on, while the dual display allows readings from either side of the instrument.

The internal angle memory can store up to 256 pairs of horizontal and vertical readings, which is useful for repeated field observations and routine construction measurement.
