The Klein Tools 935DAG is mainly designed with a strong magnetic base that helps it stick to metal surfaces like pipes and saw blades, which can be really convenient for working with metal.
But if you're asking whether it can work on non-metal surfaces, the answer is yes, though there are a few things to keep in mind.
On non-metal surfaces, the magnetic base won't help with stability, so you'll need to make sure the level is sitting flat to get an accurate reading. Calibration is pretty important here. Our research shows that the base of the gauge can be sensitive to changes in surface flatness, so you'll want to calibrate it on a truly flat and clean spot. If the surface is warped or not perfectly flat, it might mess with the accuracy.
Some folks say the calibration process can be a bit finicky, so it's good to follow the directions closely to keep your readings spot-on. Also, recalibrating it each time you switch surfaces or environments is a smart practice to keep things accurate.
One more thing to consider: while the display works great indoors, it might not be as easy to see in bright outdoor light. Plus, it tends to go through batteries quicker than you might like, so it might be a good idea to have some extras handy for longer tasks.
If you ever run into consistent alignment or reading issues, reaching out to Klein Tools for help could be beneficial. Even though this tool is better suited for metal, with some extra care in calibration and use, you can still get good results on non-metal surfaces.
