When precision counts and ease of use matters, you can"t afford to pass up the incredible Ranger Model 515 CL and 515 CLQ compasses. 1:24,000, 1:25,000, and 1:50,000 scales make plotting quick and easy no matter which type of topographic map you"re using. Also, there are 1/20-inch and millimeter rules for mapping and silicone feet for map gripping. All scales come in two colors, so they"re easy to read. They also have a large sighting mirror with a vee notch, so you can take readings on distant landmarks. A geared declination allows adjustment for the difference in degrees between magnetic north and true north, giving you a faster read and reducing chance of error.
