Bubble Level accuracy
The Lowly bubble level will surprise you

Standard digital levels have an accuracy of 0.1 degrees. But according to Johnson Level, bubble levels (also called “spirit” or “vial” levels) actually have a better accuracy of .029.

That means careful use of a bubble level will result in a more accurate result than the fancy new digital level! And they are way cheaper.

Don’t throw away that bubble level. It’s more precise than you thought. You can get a fancy digital one if you like but it’s not more precise unless you pay for a high-end model ($100+).
Few users have a legitimate need for the accuracy obtained by higher-end levels.
