Received from Energy, Mines and Resources, the federal government department responsible for surveys such as geographical, topographical, etc. The department started as Geological Survey Canada in 1842 with the main goal of preparing an inventory and assessment of the geological environment in Canada. - Function
-
Used to measure angles. - Technical
-
Arc reads from -5 degrees to 150 degrees, and the vernier reads from 0 to 10. This sextant has a double frame, which gave more support to the user when holding the sextant. It also has an interesting magnifying glass positioned over the arc. Sextants replaced older methods of measuring angles because more precision could be obtained due to the star being measured relative to the horizon, and not the instrument, which was used previously - Area Notes
