Review on Non Contact Tachometer Precision Backlight Functions by David Pirlet

Revainrating 4 out of 5

This is a laser device, do not point it at people's eyes.

Easy to use reflective tape helps keep track of RPM. Because I measured the speed. Shaft oiled, I cleaned the surface and used a chalk marker. Reading was satisfactory

Pros
  • Motion, speed and power
Cons
  • Questionable purchase for the elderly
