ESElectronic Specialti 332 Pro Laser No-Contact Photo Tachometer

The unit was delivered in a timely manner. The case is snug-fitting, but no problems. First time use was straight-forward. The reading was relatively stable, considering it's an older diesel. I was able to accurately set my dash-tach with the help of a friend. Good product.

I use this almost daily and it is accurate and easy to use.

Work well

Absolutely fantastic. Does exactly what it's supposed to do. Worked great first time out. Functions are easy to learn, has a "measure" button - to engage the laser, a "mode" for counting the revolutions and to measure the RPM and a memory button. Quality construction, feels good in the hand, very ergonomic. Comes with battery, three strips of reflective tape and a carrying case. Would buy again.

This works reliably when using the provided reflective tape cut to 1/2 x 1/2 inch size, on a non-reflective, dark-colored small motor shaft for a movie projector. I tested it as a distance of 6 inches. It does require holding down the measurement button to obtain readings, so it's not useful for continuous hands-free measurement.
