Pacific Arc - Quick Set Bow Compass Set

Quick Set Bow Compass Set

Draw precise circles up to 22 inches with professional accuracy

A precision bow compass reaches 14-inch circles without extension; add the included bar and you're working up to 22 inches. Pacific Arc designs these instruments for drafters and technical illustrators who need repeatable accuracy across large-format work. The bow mechanism maintains consistent pressure throughout the arc, eliminating the wobble and drift that plague cheaper compasses on extended curves.

The universal adapter handles standard leads, technical pen inserts, or ruling pens, letting you switch between graphite layouts and inked finals without changing tools. Four spare leads store in the integrated holder, no fumbling through drawers mid-project when your point dulls. Knurled adjustment knobs provide fine control over radius settings, holding position even when you're bearing down for crisp lines on heavy drafting vellum.

Everything nests in a rigid plastic case that protects points during transport and keeps components organized between sessions. The case matters more than it sounds, loose compass points damage easily, and a bent leg throws off every circle you draw afterward. This set stays ready for architectural elevations, mechanical drawings, or any work where circular precision isn't negotiable.
