The Fluke 424D is our most sophisticated laser distance meter packed with versatile features to save you more time in more situations and reduce errors. Just point and click to instantly measure up to 100 meters (330 ft.), accurate to + 1 mm. No scales to interpret or misread. The extra bright laser supports easy targeting even at longer distances. Extra features like a 180º inclination sensor, the corner angle feature, and a built-in compass make it easy to get accurate measurements in hard-to-reach locations. You'll be able to see the results more clearly on the large, four-line backlit display. No matter your job, the 424D laser distance meter will help you do the work of two people on your own.

Other helpful features:

Provides a compass "heading" for distance measurement

1. Applies for 100% target reflectivity (white painted wall), low background illumination, 25°C. 2. Applies for 10 to 500% target reflectivity, high background illumination, -10°C to +50°C. 3. Tolerances apply from 0.05 m to 10 m with a confidence level of 95%. The maximum tolerance may deteriorate to 0.1 mm/m between 10 m to 30 m and to 0.15 mm/m for distances above 30 m. 4. Applies for 100% target reflectivity, background illumination between 10'000 lux and 30'000 lux. 5. After user calibration. Additional angle related deviation of ±0.01° per degree up to ±45° in each quadrant. Applies at room temperature. For the whole operating temperature range the maximum deviation increases by ±0.1°.
