An Advanced Bow Compass with Pencil Adapter and Extension Bar
This adjustable quick-set bow compass gives geometry students and artists a precise, well-balanced tool for drawing clean circles, arcs, and larger geometric constructions. Made in Germany with durable steel components, it offers smooth squeeze-lever adjustment, jointed legs, and a fine-tune spindle wheel for steady control.
The included extension bar expands the drawing range up to 23.6 inches / 600 mm in diameter, making this compass especially useful for larger geometry projects, drafting, and artistic design work. The pencil adapter accepts pencils, colored leads, and ink refills up to 11 mm in diameter, allowing students to bring color, line variation, and creative detail into compass work.
This is the most versatile option in our compass collection. For a simpler first compass, see our First School Compass for Students. For an everyday precision compass without adapters, see our Quick-Set Geometry Compass.
