The geodetic surveying compass of BG 1 is widely applied during the reconnoitring, geodetic and land management works. By means of a surveying compass you will be able to carry out measurements of azimuths of the directions, horizontal corners and points on geodetic grounds, at glazomerny shooting of the district, reconnaissance, especially in the conditions of the closed forests, the rivers, the marshland.
BG-1 it is possible to operate surveying compass at temperatures from -40 °C to +50 °C, and also at a temperature up to 20 °C at the increased relative humidity (to 98%) that is confirmed with more than 30-year history of operation of this tool specialists of the most various branches.
In the course of your researches the surveying compass of BG1 is capable to maintain considerable percussions and vibration loadings thanks to what you can without fears use this device in the most extreme field conditions including on moving transport. For prevention of damages of a surveying compass during transportation you will be able to block (to zaarretirovat) a magnetic needle by means of the special mechanism.
You can buy BG 1 surveying compass for the solution of a wide range of tasks from the field of geodesy, land management, topography, forestry, the price of division of verniers makes 55 ‘-, and the price of division of a scale of a limb – 1 °. Working with a surveying compass, you will define horizontal corners with an accuracy of 10 ‘-.
Thanks to a rotary design of a limb and an alidade by means of a surveying compass it is possible to perform direct measurement of internal corners. The standard carving allows to establish on a usual geodetic support for more exact measurements. Besides, the universal fixing screw of the transitional plug of fastening allows you to establish BG 1 surveying compass on a rack or a peg.
