Description
This is our own design and is designed specifically to act as a classroom aid for teaching the use of plotters similar to the Compass-rose Plotter.
The contrasting and high visibility colours, and the large print of the scales on the base-plate and the Compass-rose disc allow the grids and digits to be read from the back of a normal sized classroom. The scales are simplified and enlarged versions of those used on the Compass-rose, plotter as described earlier on this page. However, the Compass-rose Demonstrator has a generic form and graduation that will make it an excellent tool for teaching the single-arm protractor in all of its various guises.
The advantages of the Demonstrator as an on-board chart plotting tool should not be overlooked. The reading accuracy is in no way diminished through its primary function as a classroom aid. It easily spans a standard sized chart and the clarity of the enlarged graduations make it very easy to read in poor light.
It is supplied with the same comprehensive instructions as the Compass-rose Plotter.
