I used this for wall tile installation. So amazing! I spent so many years working to a level chalk line or pencil lines only to have them get obstructed by the mortar or adhesive. Not anymore! This line is so bright and easy to see. And always visible over the mortar or tile, through open doorways and windows. Saves hours of time in job set-up & lay-out.
This lazer comes with a small platform that allows you to finely adjust the height after putting on a table or the step of a ladder. It can also project a horizontal line from the top or the bottom of the unit for more adaptability. The vertical line worked great for wall corners and lining up the grout joints. Came as accurate as my 6’ level right out of the box. Wish I had invested in one of these years ago.
