Westcott 360-Degree Compass Protractor, Crystal Clear Transparent Dial, Calibrated for 360-Degree Accuracy, Back-to-School, School Supplies, Classroom Supplies, 3 1/2-Inch

What I was after but did took a bit too long to get to me

no problems and good value for the price.

Didn't know there would be a warning label telling me that I could get birth defects and other lovely things if I used it

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.

Good tool for working with maps. The plastic has flex and appears to be good quality. The lettering looks good and price was fair. Good for calculations when using map and compass.

Used for plotting bearings on a laptop screen. Perfect for what i needed.

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.
