Your cart is empty.This digital protractor/rule allows you to precisely set and measure angles in 0.05 degree increments. The stainless steel arms are graduated inch and metric scale for convenient and immediate linear measuring. Features a hold function, ensuring you never lose your reading, and a reverse reading capability for those hard to calculate angles. The protractor measures angles from 0 to a full 360 Degrees. Packaged in a protective plastic pouch with an extra battery.

I like the repeatability. It gets the same reading again and again on test squares. The resolution is a tad low for my purpose, but fine for most. 1 more digit of resolution would make it super. I wish it took an AAA cell or small Li-Po battery because I don't like button cells. The good news is, it's a large, cheap, common button cell, and comes with a spare. The blades are a bit thin. A little thicker and stiffer blades would be make the tool better. I dislike the locking knob. It's too rounded and slippery, needing deeper knurling. The knob also self-tightens and jambs up when you rotate the blade clockwise, so It must be loosened often. The function buttons are a bit small, and the print on the buttons is hard to read. 1 star off for the locking knob, but still recommended. A nifty, useful little tool. Recommended!

Seemed to work well, but after only a day of using the holder for the battery broke and I had to return it.

I was apprehensive about the tool and its ability to to do what I needed it to do but for the price I was willing to try it. I have for years used a standard Starret protractor and been happy with it. The manual protractor has been getting more and more difficult for me to read in part because of normal wear and maybe the larger part I can't see as well as I used to. The iGaging protractor is vastly easier to read than my Strarret and easily reads to within .1 degree with as of yet unswerving accuracy. It is not as handy to use as my old protractor but I am learning and becoming more coordinated in using the tool. It has some nice features such as anywhere zero and a hold feature but as other reviews have written the lock mechanism leaves a little to be desired. The un-answered question is will it be as durable as the one it replaces. A new starret protractor is about 3 times the cost so if it lasts a third as long then I will still be way head in just the ease of measurement and increased functions. I would not hesitate to recommend or purchase another one at this point.

Bought these on a whim for a replacement to my old "analog" bevel square. All I can say is they really do make working with angles and setting up machinery a lot easier. Most important they set easilly, are more accurate and it's all repeatable.In my wood shop it is always difficult to get any machine set to exactly the same place twice when doing angles but not anymore.It's become one of those tools that I keep coming up with new ways to use so these puppies get a 10 out of 10 from me. The price is more than fair for the value.

Very impressive tool. My woodworking quality and speed just got a boost with this tool! I don't know how the accuracy could be much better. It measures to the 0.5 of a 10th of a degree. Repeatability is very good. The three buttons are: ON/OFF; ZERO; and HOLD/Rev. ON/OFF toggles with each press. ZERO establishes your zero reference and keeps that same reference when powered off. HOLD/Rev. quick press turns on a little "H" indication and keeps the number even if arms are moved. Press it again quickly and the protractor shows the angle of where arms may have been moved since the "HOLD." Pressing HOLD/Rev. for 3 seconds flips the same display upside down so you don't have to stand on your head to read the numbers. Holding for 3 seconds again flips the same number right-side-up. The read-out goes completely from 0.0 to 359.9 (with the 0.5 of a tenth of a degree too.) A thumbscrew tightens the arms, but they can still be slipped pretty easily.

I'm a Rig Welder and pipe fitter by trade.This tool is accurate and easy to read.The tool feels solid with just enough weight to it.For pipe layout and finding angles I found a nice trick to use. I unfold the protractor and lay it out up against a straight edge, then press the zero button. It saves this function and I can use it several times with out checking the accuracy. It gives me the angle with zero being fully extended and 1-90 degree as I start to fold it up. Which are the correct angles I need when runing pipe.I still save the old protractor and angle reminder incase this battery goes out. Otherwise this is my new every day use tool.

I just got my Digital Protractor hears what I foundAccuracy: off by (0.05 degrees)Testing it on a extremely accurate surface plate with a extremely accurate 90 degrees angle, at 11" away from point of intersection the line was be off by 0.002" (A piece of paper is about 0.003" thick) Well within the manufactures specks of (0.2' ±)Good Things;(1) Accuracy is as good if not better than my manual Protractors(2) Very well made, like using a set of digital calipers.(3) LCD display large very clear and easy to read.(4) Digital readout can flip upside down for odd setups(5) Battery changing is simple, no tiny screws to lose.(6) Zero Button- to reset, or to do setups in steps. VERY IMPORTANT !!!(7) Adjustable tension screw.(8) You can freeze the readout on the LCD display.(9) Auto shut off after 10 min. (not mentioned anywhere)(10) Goes up to 359.9 degrees.Bad Things;(1) Accuracy: off by (0.05 degrees) not perfect but super close.(2) When readout is flipped, the 5 in (000.05 degrees) is missing some LCD lines,(3) The 2 angle arms have 4 sets of Inch scales (Rulers) on them1/8, 1/16, 1/32, 1/64 but nothing in "thousands of an inch" or metric.Unknown Things;(1) Drop test ? it's gonna happen, but Not yet.(2) Long term usage, button wear, Accuracy ????(3) For a controlled test I would need to test 10 or more Digital Protractors, this could be the best in the bunch or the worst, who knows?Final Conclusion;Excellent !$18.90 plus shipping, not bad at all.But NOT for big jobs, Angle Lines over 10" do it the old fashion way.If I lost this Digital Protractor, I would definitely order a new one.Jon OlimbModel Maker, Illustrator, Mad ScientistAcme Design, Elgin IL.
