Review on Johnson Level Tool Pitch Locator by Bob Maldonado

About a decade later my Johnson 750 pitch and angle locator became somewhat unusable after a piece of white cardboard on the back of the gauge warped and prevented it from moving freely must move to show the slope or angle. This means that about a quarter of the tool is now unusable because the needle is being stopped by the warped white cardboard inside the tool at the back. Hence the lower number of stars for "Accuracy". It was good for the first few years before the warp came along. If the manufacturer reads, consider a plastic, glass, or metal back instead of a cardboard backing to keep it from warping.
