Feature: 1. Comfortable to hold, two‑color mold encapsulated shell, better hand feeling and convenient measurement. 2. The performance of the M70 high‑precise large optical lens is improved, and the measured data is more accurate. 3. Easy to use, a laser rangefinder can complete the work in a few seconds. 4. Very suitable for interior decoration, decoration, floor and wall materials, real estate appraisal. 5. Small and portable infrared rangefinder, which can measure 70 meters, is convenient to carry and use. Specification: Item Type: Laser Distance Meter Material: Plastic Product Size: Approx. 117x52x27mm / 4.6x2.0x1.1in Product Model: M70 Measuring Range: 0.05~70m Measurement Accuracy: ±2mm Laser Class: 2M II Laser Type: 620-690nm, <1mW Area: Yes Volume Measurement: Yes Measurement of Pythagorean Theorem: Yes Addition and SubtractioN: Yes Tracking Measurement: Yes Maximum and Minimum: Yes Backlight: Yes Prompt Tone (can be turned off): Yes Data Deletion: Yes Data Storage: 20 Groups Dust and Water Splashing: IP 54 Operating Temperature Range: 0~40℃ Storage Temperature Range: -20~65℃ Battery Life: >5000 times Power Supply: 2 x AAA LR6 1.5V (delivered without batteries) Automatic Laser Shutdown: 30s Automatic Power Off: 3min How to Use: 1. When the measurement distance is within 10m, the measurement accuracy is ±2mm; when it is greater than 10m, the measurement accuracy is calculated as follows: ±2mm±0.05 x (D-10) (D: measurement distance, unit m) 2. When measuring targets with poor reflectivity or very rough surfaces, or the ambient temperature is too high or too low, or the ambient brightness is too bright (for example, in the sun), the deviation will be unfavorable. Please read the manual carefully before operation. Package List: 1 x Laser Rangefinder(Battery not Included)1 x Lanyard1 x Manual Note: 1. It is forbidden to open or repair the equipment.2.
