The tool includes the 4 scales offered for topographic maps. Don't forget to turn on the UTM Grid option when you order your maps. Internal cutouts are shown with a red outline in the product images. The map image in the background of some product images is present so that any white ink is visible. Neither the red outlines nor the map image are printed on the tool.
