Isnt there some laser product that can help make sure you line up the nails on the wall evenly?

I need to put up some pictures and I want to make sure they are straight. I think I remember a product that helps you do that without using a ruler... anyone know what its called and where it is sold?Isnt there some laser product that can help make sure you line up the nails on the wall evenly?
The tool that advertised that was the Black and Decker Bullseye. You could attach it to the wall, and it shot a level line. A plain old fashioned spirit level can do the same thing a lot cheaper. Hope this helps.

Black and Decker have a auto level laser - you can probably find it at Ace/Home depot or lowes.


I also believe the Apple I touch has an application you can download for it as well if you have an Itouch
you can pick up a small laser level at any home center for under 15 dollars.if you want a real good one that hangs on the wall look to spend 20.+ dollars.there grate to have and saves a lot of time
tape measure and a spirit level. (also use a straight edge if required and place the level on top for a longer reach if u have a short level)
