Here I wanted to share a very short video of Digital Laser Tachometer. I use it for to adjust correct propeller rpm of my glow engines of my RC planes.
It comes with reflective types.
Direct and strong sunlight negatively affects its read, but if you use reflective types it easily reads.
You may order it on goo.gl/Yn86UQ
