Gexmil Handheld Digital Induction Chainsaw Tachometer, 2 Stroke 4 Stroke Small Engine Tachometer, LCD Display Tach Gauge for Chainsaw Lawnmowers Gasoline Engine Timed in Minutes

Works perfectly to tune a two stroke engine. Used on my stihl backpack blower to tune the andjust the carb per factory spec. Induction worked well, and price was good

There was a bunch of these inductive tachometers listed but I choose this one. It operates surprising well, I haven't checked the accuracy with trusted tools but it does match the instrument panel tach in my 2nd gen Bronco, and it appears OK used on my chainsaw. Instructions are a little vague but understandable once it's played with for a while. The 1 and 2 numbers mentioned appear to be multipliers for 2 or 4 stroke engines, still not sure about the 3, and the 4 is for reset. Have fun.

Its does well registering the rpms from small engines. Seems accurate. Very simple to use. It doesn't always register accurately, but removing it and re attaching it seems to help. Good value for the price. It reads well. Not sure on battery life yet, but seems strong.

Works great! Really convenient to use. Just place it near the spark plug wire and see how fast your engine is running with the large, easy-to-read display. I did the muffler mod, and this proved to me I had my saw set up perfectly. She eats wood like a starving beaver now. Nom-nom-nom.

Makes tuning my chainsaws much easier.

It is very easy to use and it seems pretty accurate. The only thing I don't care for is there is no way to get to the battery. The case is sealed up tight. I guess when it dies, ya toss it.

Works well out of box. Set it to position 4 for 2 stroke engines. Dropped a star as you can't change battery

bought 2 units, was a low price so why not? Neither worked as expected. On one the reading was obviously too low, the other the reading was obviously too high. Both went into the garbage. If I could give zero stars, that is what I would have done.
