Angle accuracy comes into play when working on any project as it determines your success or failure.
Several decades ago, the types of protractors used to measure angles were tedious. It took a lot of time to measure and note angles down reducing productivity.
For this reason, Digital protractors were introduced to save time, increase productivity, and better accuracy.
They employ the use of magnets and other electronic sensor technologies to provide you with accurate measurements. Most of them can be reset/ zeroed to ensure that they work correctly.
Digital Protractors are used in many fields including woodworking, sketching, and architecture to mention just a few. All these fields require topnotch tools to avoid damaging and costly inaccuracies.

Which is the best digital protractor for me?
There are two types of digital protractors, i.e. the block and the one with handles. Each of the two has some function difference in that the former measures even relative angles and can be used as a level while the latter is used to measure angles and in some cases length. Choose the one that accommodates all your requirements.
When do I calibrate my digital protractor?
If the reading is not zero when you place the protractor at a level surface, it should be calibrated.
What is relative measurement?
Relative measurement is the difference between two surfaces in either degrees, percentage incline or any other unit.
What is zeroing?
Zeroing is creating a reference point or a start point for your digital protractor. It’s useful when measuring relative angles.
Technological changes should happen even in your toolbox. The digital protractors reviewed are technologically advanced tools which aim to increase accuracy and to reduce time wastage when working on any project. Some have special features which combine different tools into one making them unique additions to your toolbox.
To make sure that you get a significant tool upgrade, consider tool versatility and your set requirements among other factors to enjoy maximum benefits.
