What it does: A stainless steel ruler with a clear digital angle display designed to mark straight lines, draw parallel lines, lay out work, and calibrate angles. The digital readout removes guesswork so measurements are fast and reliable. Key benefits: Fast, accurate readings: the digital angle display is easy to read and reduces errors compared with visual estimation. Durable construction: stainless steel material stands up to shop and field use. Practical, multi-function design: combines linear measuring and angle measurement in a single tool, reducing the need to switch instruments. Who it helps: ideal for students, machinists, DIY enthusiasts, carpenters and woodworking hobbyists, vehicle maintenance and repair technicians, and construction tradespeople. How it solves common problems: Speeds layout tasks by letting you mark parallel and linear lines quickly and consistently. Improves accuracy when setting chamfers or transmission angles by providing a direct digital readout. Simplifies drawing radial lines and calibrating components without repeated checks or guesswork. Important attributes: Function: linear marking, parallel line drawing, layout, angle calibration Material: stainless steel for durability and stable measuring surfaces Readability: digital display for clear angle values, reducing interpretation errors Compatibility: suitable for hand-held use in classrooms, workshops, construction sites, and vehicle service bays Typical use scenarios: 1. Woodworking: quickly lay out parallel lines and set precise angles when cutting joints or fitting trim. 2. Vehicle maintenance and repair: check and set chamfer and transmission angles accurately during assembly or alignment. 3. Education and drafting: students and drafters draw radial lines and calibrate measurements with a single easy-to-read tool. Why choose this tool: it combines the durability of stainless steel with a digital angle readout to make common measuring and layout tasks faster, more accurate, and less error-prone, while remaining straightforward to use in workshop and field environments.
