Description:  1. Advanced optical measurement technology. The Mastfuyi rangefinder adopts self-developed high-efficiency filtering algorithm, and is equipped with high-quality curved optical lens, so that it has higher accuracy and faster measurement speed than other products on the market. The fastest only needs 0.25S, and the measurement distance can be Up to 120m(120M FOR FY899).  2. Digital angle measurement. This rangefinder can measure the angle in real time while measuring the distance, and display the accurate angle value on the screen instantly, which is much more accurate than the common horizontal bubble. It is very useful in household and building decoration projects.  3. Large data storage space. This rangefinder can store up to 99 sets of measurement data, and is easy to recall, which greatly improves work efficiency without worrying about data loss.  4. High-definition backlight display. The display is clear and delicate, with high brightness, and can be used in bright or dim light environments.  5. Rich and complete functions. There is not only a single measurement function, but also a continuous measurement function. Not only can measure area, volume, Pythagorean, but also add and subtract measurements.     Specification:  Type: FY897; (FY899.  Measurement Distance: 70M(FY897); 120M(FY899).  Measurement Accuracy: ±2mm.  Measurement Unit: m/ ft/ in.  Digital Angle Measurement Range: 0°-90°.  Single Measurement Time: 0.25S.  Reference oint: 2( Rear, Front).  Data Store: 99 Units.  Auto Laser Turn Off: After 30S.  Auto Power-off: After 180S.  Laser Wavelength: 620~690nm.  Laser Class: Class II Battery Type: 3*AAA (Not Included).  Single Measurement: YES.  Continuous Measurement: YES.  Area/Volume/Pythagorean Measurement: YES.  Addition/Subtract Measurement: YES.  MAX/MIN Value: YES.  Measurement Unit Switch: YES.  Measurement Benchmark Switch: YES.  Sound Reminder: YES.  Battery Indicator: YES.  Product Dimension: About 115 x 50 x 25mm.  Product Weight: About 85g.     Package included:  1 x Laser distance meter.  1 x User manual.  1 x Cloth bag
