Purpose and key benefits - Use this protractor to determine course or bearing with straightforward angle readings, supporting precise navigation, surveying, and layout tasks. - The design supports hands-free timing with a stopwatch by allowing a cord to be attached through a dedicated hole, suitable for long-distance measurements. - The vertex area includes a hole that enables placing a separation point or pencil, aiding quick marking and reference setup during measurements. Core features - Protractor for determining course or bearing with clear access to measurement scales. - A cord attachment option through a hole to connect a stopwatch for long-distance timing. - Vertex with a hole to accommodate a separation point or pencil for marking or reference placement. Practical benefits - Improves accuracy in bearing and course determination. - Enables secure stopwatch use over long measurements without manual holding. - Facilitates quick marking and reference setup directly on the protractor. Use scenarios - Field surveying and reconnaissance: Establish a bearing between points along a baseline, reading the protractor scale to determine direction. - Long-distance timing tasks: Attach a stopwatch via the hole through the cord for measurements that extend beyond immediate proximity, reducing the need to carry the stopwatch in hand. - Construction layout or educational settings: Place a pencil or separation point through the vertex hole to mark positions and align layouts or teach angle measurement concepts. Notes on use and care - Ensure the cord and stopwatch are securely attached through the designated hole for reliable long-distance timing. - Use the vertex hole to place a reference point or pencil for consistent marking during measurement sessions. - Keep the measurement surfaces clean and free of debris to maintain accurate readings.
