Review on 📏 GemRed Digital Finder 18 Inch Stainless: Precision Measuring Tool for Accurate Angle and Length Measurements by Todd Calloway

This thing is pretty cool - my only complaint is the plastic turnbuckle - seems like it should be metal - as I probably find it strong too tighten - the angle tends to change 0.1 degrees or so when I pick it up to hand it to the scribe - I'm not a carpenter, just a guy trying to build a deck. I checked accuracy with speed squared - accurate (well, at least for a 90' angle.)
