Review on Non Contact Tachometer Precision Backlight Functions by David Pirlet
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
