how laser levels work - best laser level for builders

This is the case: you stand on the sofa with a hammer and nail in one hand and a flat head in the other.
You want to hang up a series of frames, but you want to hang them on a straight line. -
After all, it's not the leaning tower of pizza, kind of like --the-couch gallery.
The problem is that when you also hammer with a pile of nails, it is impossible for you to lean horizontally against the wall.
You need an extra arm to complete such a task, but you don't.
If the level can lean against the wall, you can remove the nail with two free hand hammers. Guess what?
If you have a laser in your toolbox, this wish is a reality.
The laser level projects a visible, perfect line on a surface like a wall or floor.
Since many lasers are mounted horizontally on a tripod or even on a wall, this allows your hands to freely hammer or arrange tiles with nails.

Your own projects include hanging wallpaper, installing tiles for the kitchen tailgate, installing long racks or cabinets or building decks.
