Military Protractor
This is a high quality accurate angle measuring device
Useful for map reading and outdoor pursuits
5cm (6”) RA Mils Protractor to military standard
Supplied with hard coating and string
Graduations are in Mils not Degrees
The protractor should always be used when plotting grid references and bearings.
Always,check the scale of the map and scale of the Romer when plotting grids.
Tape up the yard scale Romer to avoid mistakes.
Use a line of cord from the centre point when plotting bearings,a plumb line.
Place the protractor over the map and align the Northing’s and Easting’s with the zero lines and Romer grids.
The is the issued protractor,the meter scale Romers are on the left side;these are the Romers that you should see.
Plotting Bearings
Ensure the map is on a flat surface.align the base line with the vertical lines on the map,the 0 should be in line with Grid North.All vertical and horizontal lines should be aligned with those on the map,overlay the centre point over your location on the map(Trig Point).Then draw a line or use a plumb line to mark a line from your location(Trig Point)to your target (church with tower).
Where the line crosses the outer scale,it indicates the Grid Bearing from your position (trig point)to your target(church with tower).The puter scale is used when plotting bearings East and inner scale for Bearing West.
To plot a back bearing from the church,turn the protractor to the left with the centre point over the church.Read off the inner scale and plot a bearing of 4500 mils back to the trig point.Choose two points on a map and practice the this procedure.
