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

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.

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.

Works as described. Compact and easy to setup

I use this to check the angle on my Ruixin Pro and it works perfectly. I like the ability to Zero out to get an accurate aggregate reading. It has leveled up my knife sharpening skills for sure. I spent a little more for the Klein as it is USA made and am sure the quality is better. We have a Klein plant in the city I live in.

It works as it should, great for setting up my table saw, compound miter saw, jointer fence etc.. 4 stars because I wish that it was USB rechargeable, batteries are a pain.

If you are working with metal and need precise angle measurements, this little beauty is perfect. I’m setting up suspension on a Trail Buggy project and this tool made measuring caster angle simple and easy. Also made setting up driveshaft/pinion angle a snap. If you are a fabricator, this tool will come in handy!

Fits anywhere more accurate than a double, doesn't break when dropped off a ladder. So cheap I bout some for work. Battery life is good enough that you dont need to carry extra batteries. Super simple to use even my special ed coworkers can figure it out, and they eat paste daily!

Does everything well...stable and easy to read display. Strong magnet and outside case is flat and square. My only issue was I needed to go through the complicated calibration process to get it to Zero. Would have expected it to be ready to go from the factory.
