Klein Tools 935DAGL Digital Level Angle Finder with Programmable Angles, Measures 0-90 and 0-180 Degree or Dual Axis Bullseye Ranges

Yer handy! Good for finding angle of roof too

I’ve been using this Klein Tools digital angle finder for a variety of DIY and home projects, and it has quickly become one of my most-used tools. The display is bright, clear, and super easy to read, even in low light. The measurements are incredibly accurate, which makes leveling shelves, installing trim, hanging frames, and working on angled cuts so much easier and faster. I love the strong magnetic base — it sticks securely to metal surfaces and stays put while measuring. The compact size makes it easy to store in a toolbox or carry in a pocket. It feels solid, durable, and well-made, exactly what you’d expect from Klein Tools. If you’re a DIYer, contractor, or just want precise leveling for home projects, this is a must-have tool. Highly recommend!

I had no idea such a tool existed. I'm using it to level and polar-align my telescope. I can even make it work as a clinometer, although it's a little awkward since you can't sight down the length of it while reading the display on the side. I checked its accuracy with a 4 ft. bubble level and it is pretty accurate, but you might want to use a traditional level for, say, floor joists in new home construction, which from what I've read is a little more accurate. But for most tasks, this thing is great. Strong, built-in magnet.

This is a perfect tool for my line of work. Highly recommended for precision levels and angles.

Love this unit. Mainly use it in my motorhome where I can put it about 15 feet away and fine tune level without having to go back and forth reading a level bubble. I can see it being very handy around the house too.
