Stops working after one use

It was working when I bought it. Now, a few months later, he no longer feels any rotation. I only used it once briefly. Although the battery is fresh. It has a display, but it doesn't account for the spinning reflective tape you bought from Amazon. I messed up a test session I arranged with the engineering team

Pros
  • Resolution: 0.1 rpm, at 2.5 to 999.9 rpm; 1 RPM, at 1000~99,999 RPM
Cons
  • Can't remember

simply outputs random numbers

I put reflective tape on the flywheel of my 11hp Kohler engine. and also in different positions when I started the engine and tried to get a reading and WOW the numbers were all over the place 300 800 150 400 900 etc. I was better at guessing the RPM than it was showing. I would NOT recommend this product.

Pros
  • readings are displayed on a large, easy-to-read LCD screen; saves the last, minimum and maximum readings; Auto Zero Features
Cons
  • Something else

Decent easy to use tool, only downside is the quick auto shut off

Bought this to calibrate a tachometer on a boat and it worked great! The laser comes with several reflective strips that you stick on the gear/pulley/object to be measured. I bought a few extra strips in case I want to measure something else in the future. must be turned on again. If it weren't for that little annoyance I would have given it 5 stars.

Pros
  • Accurate to +/- 0.02 percent and can measure from 2" to 20" (50-500mm); RPM measured over 0.5 second sample time
Cons
  • Expensive
