It provides 1deg resolution for precise bearings and includes meridian lines, a magnified readout, and multiple Romer scales to support detailed map work and GPS coordinate plotting. The compass is built with a durable double-gauge, ergonomic baseplate and a rare earth magnet that resists interference and maintains polarity over time, while a reversible inch/millimeter ruler and high-visibility cling improve usability in varying conditions. Compact and lightweight at approximately 5.2 x 2.8 x 0.5 inches and 1.7 ounces, it is suitable for outdoor navigation where consistent accuracy, portability, and compatibility with map and GPS systems are required.
