Arduino lentgh meter accuracy compare with laser and tape distance!

So in this video i am comparing the distance by using a laser distance meter from DeWalt (that device i am using for quite some time on my job and it really has made my job easier and faster)
As you can see i am travelling the stop from the shortest 26.9mm to 2000mm then 3000m and back.Its callibrated to the mm as you can see!
