Review: Map protractor - Great protractor for land navigation using maps. Punched a hole in the middle with a hot needle and threaded a string through it for measuring angles across a map. I bought it for the large numbers since so many others have very small numbers. Plus it was dirt cheap. Very convenient size. Very sturdy and will likely last a long time.

### ⭐⭐⭐⭐⭐ Excellent Protractor for Maps
*by T***N on June 3, 2021*

The Westcott 3.5-inch 360-degree transparent protractor is ideal for use on topographic maps. The protractor is just the right thickness and easy to read. I use mine with a thin black fishing line running through the center (punch two small holes, one hole 1.0 cm above the center toward N and another hole at the center of the protractor, thread the line through the two holes, with a knot in the first hole and pass the thread through the center hole) to determine the direction angle from a starting position to destination. The same black line is then used to determine the distance to the destination with a map scale. I prefer this method rather than using a baseplate compass to determine the correct direction to a destination. It is accurate to about 1-degree if the protractor is aligned correctly from starting position to destination with the map’s parallel north/south lines. Simply adjust the compass to the degree that was determined and hike away with knowledge about distance and direction. This method is used in Great Britain, Austria, and Germany by various mountain and hiking clubs.
