Baseplate compasses are great all-around hiking and travel compasses. They often have a clear baseplate, which makes them great for map use. The more expensive baseplate compasses generally have slightly larger capsules with longer needles, improving the readable accuracy of the compass. More expensive baseplate compasses also add special features like adjustable declination, map scales, a magnifying lens, luminous points, cut-outs for map marking, and even a global needle.
