Orientation measuring institution:It is composed of compass, sight and sight. The outer circle of the azimuth division is a 360° division with a mum division value of 2°; the inner circle is a 60-00 density division , and the mum division value is 0-20 divisions. The conversion between density and degree is shown in the table.Measurement accuracy: ±0-10 dense position ±1°2. Distance estimator:It is composed of rear sight and front sight. The angle between the two tips of the front sight and the center edge of the rear sight is 1-00, the length between the two tips is 12.34 mm, and the length between the rear sight and the front sight is 123.4 mm, which constitutes a 10:1 ratio ranging estimator.Measurement accuracy is 5%
