Zone Balancing

Dials in magnetic compasses should be balanced to compensate for dip caused by the earth's magnetic field. All Ritchie Compasses are standard balanced for Zone 1 (essentially all of the northern hemisphere). Compasses cannot be zone balanced in the field. If unsure of the correct zone to order, contact our Sales Department at sales@ritchienavigation.com for additional information.
