A prismatic compass is a navigation and surveying instrument which is extensively used to find out the bearing of the traversing and included angles between them, waypoints (an endpoint of the lcourse) and direction.
Furthermore, what is a lensatic compass used for?
The lensatic compass is used to determine “azimuths” or “compass bearings” (horizontal angles). It is also used to follow a course over the ground, orient or set a map, and determine position of objects in relation to a map. 1. Luminous Bezel Indicator: Used to mark an azimuth during day or night.
How do you use an engineer compass?
Use the engineer compass to measure the azimuth to take a bearing or direction. Open the engineer compass until the cover is 90 degrees to the compass case. Tilt the lens bracket approximately 30 degrees from the perpendicular position of the compass. Check that the dial is floating freely.
What is the purpose of a mirror on a compass?
Using a compass to get a bearing to a distant target. Hold the compass level with the mirror at about a 45° angle. Use the sighting notch to align the compass with the target. Looking into the mirror, turn the dial to align the orienting arrow with the north needle.
