2. Core Product Advantages

Ultra-high Measuring Accuracy with Tiny Error

Effective measuring range covers 0.05m to 100m, with a constant tolerance of ±2mm. It delivers stable and reliable data whether for short-distance indoor house measuring or 60-meter long-distance outdoor surveying, eliminating human errors and environmental interference from steel tapes and ultrasonic meters.
Class II Safe Red Laser

Equipped with 620~670nm visible red laser with power less than 1mW, complying with Class II laser safety standard, which is harmless to human eyes under normal use. The clear red laser spot enables fast targeting on walls, cement ground and metal panels, suitable for both indoor and outdoor use.
One-button Switch for Multiple Measuring Units

Supports three measuring units: meter, foot and inch. It meets the demands of domestic construction projects and overseas foreign trade projects without manual unit conversion, offering intuitive readings.
20 Groups Data Storage for Batch Survey

Built-in data storage chip can save up to 20 sets of historical measurement data. No paper and pen are needed during multi-point acceptance and multi-house measuring; historical data can be checked at any time to greatly boost working efficiency.
Ultra-long Battery Life

Powered by 2pcs AAA 1.5V alkaline batteries. Fully charged batteries support up to 5000 measuring operations, reducing frequent battery replacement and lowering daily operation cost for long-term site use.
Wide Temperature Adaptability & Good Storage Resistance

Working temperature ranges from 0℃ to 40℃, ensuring stable performance for outdoor operation in spring, summer and autumn as well as normal-temperature workshops. Storage temperature ranges from -20℃ to 60℃. Its internal optical and circuit components will not be damaged under low-temperature winter storage or high-temperature car storage, requiring no special temperature control during transportation and storage.
Portable & Wear-resistant Body Design

Mini handheld size fits workwear pockets and tool kits, matched with leather storage pouch and anti-lost lanyard. The anti-slip and drop-resistant shell withstands minor bumps on construction sites, easy to carry and not easy to lose.
User-friendly Operation, Zero Learning Cost for Starters

Function buttons are clearly divided for ranging, unit switching and data checking. Easy operation without professional training, suitable for decoration and construction beginners.
