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

For the price, it works well and is accurate.

Excellent tool that blessed my husband for his job

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.

Used it right away to make a GMRS radio cabinet with weird angles. Measured perfectly and set the cuts with ease.

Easy to use and no backlash in the pivot

Good product

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. A nice addition to a woodworker’s toolbox.
