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

Good service

Makes leveling travel trailer easy .

the product calims to be accurate to 0.1 degrees but if you zero the display then turn the product on its side it reads 89.6 degres not 90 degrees. Turn it onto its other side and it reads 89.7 degrees. Turn it back to its base and it returns to 0.1 degrees, not to zero.

Worked great

excelente aparelho

Pues muy. Útil y practico

This tool might be fine for setting steel studs in framing, and on pipes or metal fencing, but I wouldnt use it for setting angles on a table saw blade for fine joinery. The accuracy claimed by the manufacturer is one tenth of a degree (.1°) in the area of 0°-90° and two-tenth (.2°) elsewhere. It delivers that, however I assumed it would be dead on at 90° at least. I used the Zero function to test it on a 12 Starrett reference square, known to be accurate to .001 over 12, and the device was a tenth of a degree off 90° in two directions, as shown in my pictures attached. I cross-checked it against a second machinists reference square, 6 this time, and experienced a similar result after re-zeroing the device. You can set a table saw blade more accurately by eye with a square than with this device, though it would be accurate enough to set a saw blade for rough tasks like framing. I gave it four stars because it was cheap, but frankly, Im disappointed because I wanted it for use to set-up machinery, but will likely use it less than I anticipated due to this limitation on accuracy for my purpose. The device cannot be owner recalibrated to overcome this issue.

Very Handy Little Protractor.Pocket sized.

Durable for field work

Im impressed with how accurate and easy to use this is. Its small enough to fit into tight spaces, and accurate for all things ranging from leveling pictures on the wall, to ensuring landscape drains/gutters/etc go downhill at a steady pace, to measuring pinion angles on my Jeep.
