Suunto MC-2G Global Compass
The Suunto MC-2G Global Compass is a precision instrument with a true global needle, adjustable declination, and mirror sighting that delivers top-tier accuracy for professional map plotting and protractor work. It earns market-leader status here for its superior technical accuracy and hemisphere-independent performance, which justifies a higher price than Silva and Brunton for users who need consistent, survey-grade bearings when converting between grid, magnetic and true north. When pairing with map scales and protractors, Suunto’s finer tolerances reduce cumulative plotting error, making it the best choice for demanding cartographic and navigational tasks.

MapTools Super GTA Tool
The MapTools Super GTA Tool is a specialized map plotting protractor engineered for converting Grid, True and Azimuth bearings directly on map scales, making it indispensable for precise grid-to-true angle work and military-style plotting. It secures its position as best-in-class among protractor tools for this use case because it supplies conversion and plotting functionality that standalone compasses lack, offering a clear technical advantage for map-scale correction and professional plotting workflows; its price sits between classroom protractors and electronic plotters, representing a strong value for specialists. When paired with accurate compasses, the Super GTA Tool removes much of the manual calculation, streamlining scale-aware plotting tasks.
