This protractor is designed to help you determine a course or bearing, mark precise lines, and manage timing over distance with a simple, integrated setup. Key benefits - Clear angle to determine course or bearing: use the protractor scale to read and set bearings accurately. - Precision marking capability: the vertex includes a hole to place a separation point or pencil for clean, marked lines. - Long-distance timing option: a cord allows attaching a stopwatch to the hole for timing tasks over distance. What makes it useful - Function focused: supports angle measurement, marking, and timing in a single tool. - Compatibility with common tools: accepts standard pencils or marking points and accommodates a stopwatch via the designated hole. - Practical design for field work: compact and straightforward to use in surveys, navigation, or engineering tasks. Use scenarios - Surveying and boundary work: determine bearings between points and mark reference lines directly on-site for later work. - Orienteering and field navigation: set and follow bearings on maps or in terrain, using timing for pace or sequence steps. - On-site engineering or construction tasks: read angles accurately, mark lines for reference, and time procedural steps when distance matters. Notes on attributes - Function: measures angle to determine course or bearing, marks lines via a pencil or pivot point, and supports timing with a stopwatch attached through the hole. - Compatibility: designed to work with standard marking tools and external timing devices through the hole feature. - Size and material: not specified in the provided description; designed as a standard protractor with a vertex hole and a cord-accessible layout. - Performance: built for straightforward, field-friendly use in measurement and timing tasks.
