Review on 📏 92379 Rail Free 24 Inch Smarttool by Bob Randles

Very good level with excellent accuracy. Please note that you need to calibrate this instrument before using it for the first time (and after it has been hit or bumped, or after it has been standing for a long time). I took my new layer to line the windowsill I was framing. I finished framing the window sill and decided to double check with my old 48" level and it was off by over 3/8". I double checked with another cheap 24" level and it matched my usual 48" level. I did the calibration procedure and this level also showed the threshold at 3/8".
