Being in the wrong place at the wrong time can cost you your life. That's why Delta Gear relies on these accurate protractors. The Square Military Protractor is great for a classroom since the degree scale marks are more spaced and distinct. The protractors were innovated with a declination update, a GM angle conversion and an imprinted back azimuth. It features three square cut outs with the following scales:

• 1:25,000 scale

• 1:50,000 scale

• 1:100,000 scale

• 2km linear scale for 1:25,000

• 4km linear scale for 1:50,000
