You need a compass that actually holds its point when you're drawing an arc or measuring a distance off a map. Not one that drifts after two passes. This Arco compass is nickel-plated for a smooth, low-friction pivot, easy to grip, and it slips into a plastic wallet so it's not rolling across the desk. Whether it's a Year 10 geometry task or checking bearings on a topo map, it does the job without fussing
