"This is the same tool sold by Mac Tools. I use it all the time to check max rpm of outboard engines. It gets used in a more demanding environment than most. The tool is indispensable, that's the problem. It looses its' sensitivity over time and mine has been back for repair twice. It is expensive to repair. The switch buttons have a tendency not to work , again, after time. The antenna is flimsy. I am on my third smart-tach and I would love to find a more durable, sensitive, and better built alternative."

"I used the SmarTach Digital tachometer to check the idle RPM on a single cylinder 4-stroke off-road motorcycle and it had some difficulty picking up the signal. When it did acquire the signal it told me the RPM was fluctuating about 100 RPM. That seemed odd because it didn't sound like it was fluctuating that much. Could have been imperceptible, though. I was able to set the idle in the range I wanted it, and that was good enough. I did use this meter to check the RPM on a 4-cyl Honda Civic and it picked up a signal quickly, was rock-solid, and closely matched the car's tach. I'm happy with it, and it's very easy to use."
