2.PURPOSE
2.1.Binoculars range finder LRB 20 000 AEP 36.28.001 is a device of
2.2.The range finder complete with the Angular Mount is designed for referencing ground location point by the predetermined landmark coordinates and is capable of:
- measuring horizontal angles and magnetic azimuths: - measuring vertical angles and angles of elevation;
- determination of target and landmark polar coordinates; -
from the predetermined landmark coordinates.
2.3.The range finder may find application in geological and engineering survey, repair works, maritime navigation, meteorology and tourism.
2.4.The range finder is operable in the temperature range between
2.5.Power to the range finder is supplied from rechargeable battery 10
