A professional precision compass with masterbow mechanism and hard case for accurate technical drawing

The Staedtler Mars Comfort 551 01 is a professional masterbow compass with a centre-wheel adjustment and precision needle, supplied in a hard plastic case, designed for architecture, engineering and advanced technical drawing where precision circle drawing is essential.

The masterbow compass is the professional format used by architecture and engineering students in tertiary institutions - characterised by a separate screw-adjustment wheel above the body rather than a simple spread-leg or centre-wheel below the body. The masterbow mechanism allows very precise radius setting by rotating the adjustment wheel, which moves one leg through the full adjustment range in a controlled, reproducible way. The compass accepts compass leads for precise line drawing and has a ball joint where the lead leg meets the body for constant lead angle regardless of circle size. The Mars Comfort body has rubberised grip zones. Hard case protects the compass between uses. A significant step up from school compasses for professional-grade work.

  • Masterbow mechanism for precise, reproducible radius adjustment
  • Ball joint lead leg maintains constant lead angle for consistent line weight
  • Mars Comfort rubberised grip zones for comfortable extended use
  • Hard case for protection during transport and storage
  • Precision needle for a clean, accurate centre pivot
  • Professional instrument for architecture, engineering and advanced technical drawing
  • Architecture and building design circle and arc drawing at professional level
  • Engineering and technical drawing course work requiring a professional compass
  • Advanced student technical drawing specifying a masterbow compass
  • Professional drafting alongside Mars set squares and scale rulers
  • Precision geometric construction requiring reproducible radius settings
