Money well spent!
I rarely give 5 stars but this tachometer gets a solid 5 star review!
Hold the antenna 1 foot away from the spark plug or its cable and you immediately get an RPM reading. It shows you a steady maximum and minimum reading also.
I used it on a Tecumseh powered generator and set the engine to a steady 3,200 rpm's.That gave me almost a perfect 120 volts output at the receptacles. If you walk away from the running engine it still holds your readings.
Made in Canada and really made well from what I can see. The voltage to the plug feature works well and now I know the coil produces slightly over 30,000 volts.
Why did I wait so long to buy one, This meter exceeded my expectations!
