BRUNTON COMPASS AZA1042
The Brunton Compass AZA1042 from Azalab is a professional-grade field instrument engineered for high-precision geological mapping, structural analysis, environmental surveying, and navigation. Recognized globally as the industry benchmark, this compass is trusted by geologists, civil engineers, surveyors, archaeologists, researchers, and students working in demanding outdoor environments.
Unlike conventional handheld compasses, the Brunton Compass is a multi-functional surveying tool, integrating a magnetic compass, clinometer, protractor, and mirror sighting system into a single compact instrument. This versatility allows accurate measurement of azimuth, strike, dip, inclination, and slope angles, making it indispensable for scientific fieldwork.
Description
Precision Engineering & Accuracy
The AZA1042 features a precision-balanced magnetic needle with rapid settling time, delivering stable and reliable directional readings even in areas with mild magnetic interference. The manual declination adjustment mechanism allows users to compensate for local magnetic variation, ensuring true-north-referenced measurements — essential for professional mapping and survey accuracy.
Its integrated clinometer (±90°) enables precise measurement of vertical and inclined angles, making the compass ideal for structural geology, stratigraphy, fault analysis, mining exploration, and slope stability studies.
Mirror Sighting & Field Alignment
The built-in mirror sight and peep sight system allows simultaneous viewing of the compass needle and target object. This alignment method significantly improves bearing accuracy during triangulation, traverse surveys, and long-distance navigation.
Rugged Construction & Portability
Manufactured with a die-cast aluminum housing, the AZA1042 Brunton Compass is designed to withstand harsh weather, rough handling, and prolonged field exposure. Its compact form factor and lightweight design (200–300 g) make it easy to carry in a field vest, survey pouch, or backpack.
A tightly sealed lid protects internal components from dust and moisture, ensuring long-term reliability in rugged terrain.
