Leveling with a laser level. Woodworking Learning 

Laser levelers are very useful for interior construction.
In the past, we used to use water level, but now we use a laser leveler unless it is a special case.
The laser level is available in electronic and mechanical ways.
While the price / performance ratio is excellent for electronic levelers, this does not mean that mechanical levelers have a large margin of error.
Through this channel, I convey various basic knowledge, so I hope to learn my thoughts and small interior construction know-how and make a positive development both as a hobby, business and work.
