Why We Balance Certain Needles

Magnetic needles not only align with magnetic north but also dip up or down depending on latitude. If a needle dips too much it won't freely rotate, and compass accuracy can be affected.

Transits

Transit Balance Map PDF

Brunton transit needles are global but should be balanced for their main zone of use. Needles are accurate several zones N or S of their main zone.

NOTE: Special balancing may require additional production time.

Brunton OmniSights and GeoLites are built with a simpler magnet than our transits, but their accuracy is still optimized if the main zone of use is chosen.
