In my opinion, this is the best option for the measurer to have in their toolbox. There is a button that allows you to reset the angle, which means that you can measure different angles in relation to the one that has already been determined. The fact that it does not activate itself while the two devices are separated is, in my opinion, a significant advantage. The smart caliper already includes two batteries that are just lying around in the box, and they are activated by vibration. Rulers made of steel can serve two purposes: first, as the arms of a protractor, and second, as the actual ruler. It is more space-efficient than aluminum in comparison. It is possible to calculate the corner's curve with a length of 500 millimeters, which is more than enough. Well, with the exception of the fact that it might be a case, this is already more of a whim. Excellent resource. I would suggest.
