Divider compass Adar Cyrkiel MIX — precision drawing compass for circles and measurements

Adar Cyrkiel MIX — precision drawing compass for circles and measurements is a compact compass designed for accurate construction of circles, arcs and for transferring measurements. The instrument has adjustable legs and a fine adjustment mechanism that allows precise radius setting. Lightweight and easy to handle, it is suitable for use on paper, cardboard and other thin drafting materials in educational, drafting and hobby environments.

Advantages

The compass offers a fine adjustment screw that ensures repeatable and precise radius changes and stable positioning during use. Its adjustable legs provide a wide working range while maintaining stiffness for accurate drawing. The product is compact and light, making it convenient for students and professionals to carry and store. Durable metal components and a replaceable lead/needle design support long-term use and maintenance.

Suitable for

• School geometry and technical drawing classes
• Architectural and engineering sketches on paper
• Hobbyist model-making and craft projects on cardboard
• Precision circle marking and measurement transfer

Key specifications

• Adjustable leg length for variable circle radii
• Fine adjustment screw for precise radius setting
• Suitable for use on paper, cardboard and thin drafting materials
• Lightweight and compact construction for portability
• Metal components with replaceable lead/needle

How to use

Place the needle point at the circle centre, set the desired radius by sliding the legs and use the fine adjustment screw to achieve the exact measurement. Hold the compass perpendicular to the surface for consistent line quality and rotate the instrument smoothly to draw a full circle or arc. For transferring measurements, fix one point with the needle and mark the second point by rotating the compass between positions; repeat as needed. Replace the lead or needle if wear affects precision.

Usage recommendations

Use on a stable, flat work surface to maintain accuracy. When storing, retract the legs slightly and protect the lead/needle tips to avoid damage. For best results on thicker paper or card, use gentle pressure and verify radius settings with a ruler before drawing.
