The choice of laser measuring tools in the modern market is simply huge. In the store you can find models with different capabilities, both professional and amateur. The main difference between the laser level from other similar devices — optical and digital levels — is the established compensator and the absence of the optical part. When using an optical device, when performing work on the rail, you need to look through the eyepiece, and when the laser level is used, the readings are looked at the rake located around the device.
