Klein Tools 935DAG Digital Electronic Level and Angle Gauge, Measures 0 - 90 and 0 - 180 Degree Ranges, Measures and Sets Angles

This is an extremely handy thing to have and it works great! Built well and seems to be very accurate. I love that I can bring this for projects instead of my big level. The price is great for what it does.

The Klein Tools 935DAG Digital Electronic Level and Angle Gauge has been an excellent tool for precision work. I primarily use it with my knife sharpener to make sure I’m getting the exact angle on my blades, and it’s made a noticeable difference in consistency and sharpness. The digital readout is clear and easy to read, and it quickly measures both 0–90° and 0–180° ranges with accuracy. The magnetic base makes it easy to attach securely, and the compact size means it doesn’t get in the way while sharpening. ✅ Pros: Accurate digital readout for precise angles Measures 0–90° and 0–180° ranges Magnetic base for secure placement Compact and easy to handle Great for sharpening, woodworking, or general leveling tasks ❌ Cons: The small display might be harder to read in low light Requires batteries (included, but be sure to keep spares) 💡 Tips: Place it on your knife sharpener’s guide to ensure perfect sharpening angles. Store it in a safe spot to avoid dropping, as precise tools can be sensitive. Works great for other uses too — like setting angles on saw blades or woodworking tools. Always calibrate before use to ensure maximum accuracy. Bottom Line: The Klein Tools 935DAG is a versatile, precise, and reliable angle gauge. It has made my knife sharpening far more consistent, and it’s a great tool to have for any project requiring accurate angle measurements.

I use this in the wood shop all the time. Much more accurate than the gauge on the machine. This has made changing angles quick and easy. The quality is top-notch, like most of Klein's tools. The power of this magnet is wonderful. I attach it to the blade, and it stays there.

Love this item. Works so good and more accurate than others I've used.

I mean, I know why plastic. Plastic cheap. But it still feels weird that a device that can measure tenths of degrees is relying on a base that can be deformed as easily as whatever plastic this case is made of. You can recalibrate the level; it works by placing it on a surface, then rotating it to face away from you. This should reasonably find true level, as long as the base and surface are flat. But almost anything could cause a plastic base to be not-flat. Almost anything can deform this sort of plastic. It does come with a nylon case, which should hopefully prevent incidental deformation, and I suppose that if something else happens to it, you should be able to sand down the plastic to get it flat again and then recalibrate. The recalibration process is not hard, but it's not exactly obvious. It does come with an instruction leaflet that explains how to do it. It seems like it would be a no-brainer to make it so that the leaflet fit in the case, but apparently the person who designed the instruction leaflet didn't think that far ahead. I mean, it'll fit, but you gotta kinda cram it in there. That said, it works well and is reasonably easy to read. I personally think that the icon that shows which direction it's tilted is backwards from what it ought to be, but worse things have happened.

Use it to work. Great tool, easy to use and it is accurate! Small easy to transport. Great tool!

Arrived fast. Works great, I use it to verify and set angles on my tablesaw, bandsaw and miter saw. I also have one at the shop to verify vehicle frame angles when performing wheel alignments. Small and lightweight but easily readable with its bright screen. Magnetic to allow for it to hold itself to the frame of the vehicle, saw blades, or tables and then I can just stick it to the outside of my cabinet or tool box for easy access the next time I need it. It is also significantly less expensive than some of the purpose built options for measuring frame angle. Very useful tool when you need to measure or verify angles but don't want to use a protractor.

A tool that every fabricator should own. Easy to use, breaks down the angle to .1 of a degree. Can zero it out for good accuracy to the part you are trying to fit up. Highly recommend this purchase for any welder/fabricator.
