Yes, the very first project I worked on was exactly that, I needed to measure up and down from an already existing hole, put the laser light line on the hole, make sure its level, anchor, and done! nice straight laser light was on the wall, it has two levels built-in.

You can buy in any office depot pin that are uses to hold papel on cork boards, them work fine in case you news them quickly.

Hello Pete, Thanks for your question on the RYOBI ELL1750 Multi Surface Laser Level. Yes, this level can be used on the floor. - Eve

I used it on a 20+ foot wall, and it was fine. Obviously if the room is darker, it would work better.

I recommend using it either early in the morning or late evening when the sun brightness is lower.

Thank you Rick for your inquiry. The ELL1750 is not designed for or be best suited for the inquired task. ~best regards, Ashley

It uses pins to attach to the wall, so it won't work on concrete unless you rig something up.

Look answered this question once.

Nope.... you’ll need 2 for that and maybe a triangle measure for accuracy./ This took is accurate, not not meant for projects that require extreme accuracy ( though it can come close) .... basically this is for painting, handing pictures, etc..... not granite counter tops or building doorway etc..... this too accuracy is within 1/16 of an inch or the width of the beam.
