Key benefits and why you need it Accurate, versatile measuring: Supports straightline, circle, arbitrarycurve, and cylindricaldiameter measurement so you can handle flat surfaces, round objects and irregular shapes with one tool. Faster, fewer errors: Builtin totalization and subtraction with storage of up to 10 history records lets you add/subtract multiple measurements without switching devices or doing manual calculations. Extremely portable: At just 15 mm thick and 30 g, it's far smaller and lighter than traditional tape measures — easy to carry in a pocket or toolbox and ready whenever you need it. What makes it stand out Wide range: Measures distances up to 99 m and supports a 0–9 m range for shorter tasks, covering everything from room layouts to larger outdoor measurements. Multiple measurement modes: Choose the mode that matches your task (straight line, circle, arbitrary curve, cylindrical diameter) instead of forcing workarounds or guesswork. Builtin memory and math: Save time by totaling or subtracting values and recalling the last 10 records for quick verification and repeat measurements. Practical use scenarios Interior design and renovation: Quickly measure room lengths, window and door openings, and circular fixtures to plan layouts and materials. Plumbing and HVAC: Measure pipe diameters and curved surfaces accurately for fittings, replacements, and clearances. Field and site work: Take longdistance measurements up to 99 m for exterior sites, landscaping, or large equipment positioning, then store and total results for reporting. Features and performance Measurement modes: Straight line, circle, arbitrary curve, cylindrical diameter measurement. Memory and math: Totalization and subtraction functions with storage of up to 10 history records. Range: Maximum distance 99 m; supports a 0–9 m range for shortdistance tasks. Size and weight: 15 mm thick, 30 g — compact and lightweight for allday carry. How it solves common problems Eliminates guesswork when measuring curves or round objects by providing dedicated modes for those shapes. Reduces manual calculation errors with ondevice totalization/subtraction and a 10record recall. Replaces multiple tools by combining longdistance and shortrange capability in one compact device. Who it's for DIYers and homeowners who want a single, compact device for home projects. Tradespeople who need reliable measurements onsite without bulky tools. Designers and installers who measure both straight and curved surfaces routinely. What to expect in use Simple mode selection to match the surface being measured. Immediate readout and memory storage for repeated checks. Lightweight, pocketsized convenience for carrying between job sites or around the house.
