Clear- Cross-Line / Horizontal / Vertical : It is a point-to-point level that projects several horizontal and vertical laser lines using multiple LED diodes.
- Rotary: Projects a rotating dot to create a 360-degree line. A detector is used to read the laser lines over long distances.
- Dots / Points: Displays a point that can be level, square, or vertical.
- Red: It is ideal for indoor tasks and short distances.
- Green: Offers excellent visibility, especially outdoors and over long distances.
- Self-leveling: It offers a much higher degree of accuracy and is better when placed on the flattest possible surface.
- Pulsed: The laser flashes very quickly (at a frequency that is not visible to the human eye). This function allows the use of a laser detector, so that the beam can be detected even at very long distances or in bright light (e.g., for outdoor work).
- Measurement Accuracy: It expresses the maximum deviation of the beam from the true alignment at a specific distance. The smaller this value, the more accurate the tool.
- Beam Wavelength: It directly affects visibility and determines whether the beam will be red or green. The wavelength of the green beam is 515-532nm, while the red beam is 635-670nm.
- 515nm: Low to medium visibility, suitable for short distances.
- 520nm: Balanced visibility, suitable for indoor and outdoor spaces with sufficient brightness.
- 532nm: High visibility, ideal for long distances and outdoor work in bright light.
- 635nm: High visibility for red beam, suitable for medium distances and indoor use.
- 650nm: Medium visibility, suitable mainly for short distances and basic applications.
