Take the guesswork out of measuring, marking and reading angles—no tricky geometry or complicated calculations required—with the Denali Digital Angle Protractor. Simply swing open the tool’s pivoting leg and immediately read the angle on the digital display window. The tool is accurate within 1 degree, and will read angles ranging from zero to 185 degrees. The anodized-aluminum protractor is also fitted with two bubble vials for use as a conventional level. The Denali Digital Angle Protractor weighs just over a pound, and measures a slim 1 inch by 2 inches by 18 inches. It’s powered a single 9-volt battery (included) that typically lasts about 100 hours of normal use. The tool comes with a protective carrying case that’s equipped with a convenient steel belt clip.

Denali 18-Inch Digital Angle Protractor with Carrying Case

I may be the wrong person using this angle finder.Being a machinest all my life, I must deal with thousanths of an inch and seconds of a degree.So whe I took this out of the box and checked it with my master square,it was .6egrees off.When your cutting 22.5 degree angles,.6 of a degree makes a large mistake when yuo put your miters together.It was within the 1 degree +/-.One degree is a mile when you put your miters together.
This item is great for the price. Although the specs in the box only idicate an accuracy of +/- 1degree, I have measured and checked various angles to find an accuracy of +/- .1 degree, which is the precision of the LCD. It is a decent construction extruded aluminum body with plastic components at the joints. Very well worth the money when compared to more expensive name brands that will cast well over $100.
i have been a cabinet maker and finish capenter for some 45 years and i have never seen a piece of equiptment that can make cutting angles grater than a 45degree or a 90 degree any easier it’s great for base molding chair rail molding or even crown molding
I was a little nervous when I purchased this item as accuracy is only listed as 1 degree. I just finished making a regular pentagon shaped light fixture, and was delighted with the tool. I set the table saw with a digital angle guage to 54.0 degrees and cut the sides. When I put it together it seemed to fit very close to perfectly. After sanding, I checked the exterior angles with the Denali to see how accurate it was. To my complete surprise, 3 of the angles measured 108.0, and the other 2 were 107.7 and 108.3, the sum total being exactly correct at 540 degrees. I had suspected earlier that the accuracy was much better than 1 degree, but this confirmed it to me. I am confident in it to .1 degrees. I don’t know if the one I got is exceptionally good, but it performs really well.
For the price, this is a great buy. Accuracy is as described. It would be nice to be a alittle more accurate, but cannot complain for the price paid. Workmanship seems very nice.
