Digital Angle Finder Tool for Woodworking 7 inch / 200 mm, Stainless Steel with Case, Digital Protractor Angle Finder for Measurement by S&F STEAD & FAST

Well made easy to use and accurate. Price was great! I use it mainly to measure my saw angles before cutting. It’s nice to have another tool to double check.

Accurate. Useful. Price good

Nowhere was it listed about the accuracy. Accuracy is only +- 0.3 degrees. I was suspicious about them not listening it anywhere. Resolution is 0.05, but since the accuracy is only +-0.3 it makes the resolution not great. I like the product as an engineer I needed the accuracy it for easier angle measurements without high cost. Product does the job and it didn’t cost me over $100 like it would through Granger. Obviously it is not able to be calibrated, and cannot be used for ISO/IATF compliance, but it gives me a good reference measure for quick checks and comparisons.

works like a charm. Easy to use and worth every penny. We use it to verify 45-degree angles on a miter saw and the molding for picture frames.

Good tool we'll build

I compared two Digital Protractor Angle Finders: "S&F STEAD & FAST" & GemRed (2 black button version). I was hoping for a clear winner to make my decision easy, but I did not get that.Commonalities: Both brands are made in China, use the same battery, & are the same length (400mm, ~15.75 inch when fully opened). They both keep the battery in a no-tools-needed, easy to open "drawer" so it's easy to remove the battery to prevent battery drain during storage. I won't be using this every day or even every week, so this feature is important to me.Build Quality: Both rulers are the same thickness of SS (Stainless Steel), but they are different types of SS. The S&F is attracted to magnets and the GemRad is not. (There are over 50 types of SS & some are attracted to magnets.) Since they don't say what types of SS they are, I give the edge to the non-magnetic GemRad.The S&F has thicker sturdier plastic (especially the battery drawer). The GemRed battery drawer opens a bit too easily (if jolted, the drawer can open & the battery can disconnect). The S&F battery drawer opens stiffly.Finding Angles: As it should be, the GemRed angle ruler is easy to move when the lock knob is loose and it gets stiffer as the knob is tightened. The S&F however, is stiff to move no matter how loose the knob is. That would be a disadvantage when I'm measuring angles of things that flex when I push on them. Turning the S&F knob very tight makes in only a tiny bit stiffer.Ruler: The S&F ruler markings are darker & much easier to read. The metric markings on both brands go from 0 to 400mm. As you might expect, the S&F inch markings go from 0 to 15 & 16/32. Inexplicably, the GemRad imperial markings go from 0 to 7 inches, twice (instead of a continuous 0 to 15.5")! IMO, GemRad fell down on that one.Buttons: A quick press of the GenRad [On/Off] button only turns off the display, while the rest of the electronics continues to invisibly waste the battery (unless I remember to hold the button for 3 seconds). I don't like that. The S&F has 3 buttons & more functionality than the GemRad. The S&F has a [Hold] button, which could be handy in a situation where I can't see the display while measuring some angle. The S&F also has a button to display in degrees & minutes, instead of decimal degrees, but I doubt I'd ever use that feature myself.(The GenRad has some "hints" on their instruction sheet. One is "Never leave it outside in a wet and shiny environment." Another is "Do not use as a weapon to hit people." That seems like good advice -- a rock would make a better weapon.)I went back and forth about which one is better for me. The S&F is better than the GemRad in so many ways; however, I could not get past the S&F angle measure stiffness and non-functional lock knob. Since I plan to use it mainly to measure angles (not as a ruler), the GemRad is better for me. I'll have to remember to use the battery door as my On/Off switch.

Very accurate and a nice tool
