LinkstyleLinkstyle Small Engine Tachometer, Digital Tachometer Tach Gauge Reset Function Equipped with Clip, Inductive Hour Meter for 2 Stroke 4 Stroke Small Engine for Cropper Generator Lawn Mower RV

I honestly didn't think this cheap little tach would be worth a hoot but, it surprised me. I mean, it works pretty good for what it is and I've dropped it a couple times. Still going. Maybe I just got a good one but, my experience is beyond expectation.

I haven’t used it yet, but I’m sure it’s great.

When compared to an official Stihl tachometer at a certified Stihl repair shop, this tachometer was roughly accurate for lower RPM’s (~2,500-3,000), but inaccurate for higher RPM’s (8,500-9,500). At the higher RPM’s the tach seemed to either cut the RPM’s in half, or show them as being 1,000-2,000 too low. This was during use on a 2-stroke Stihl KombiEngine, and with the option for 2-stroke being selected on the tachometer. It was also for both the induction and physical clamp modes of the tachometer.I liked the ease of use provided by the clamp and induction measurement. Had the device been accurate I would have kept it. The price at ~$16-17 would have been great for an accurate and dual mode tachometer. I didn’t test for RPM’s over 9,500, nor test it on other engines.Addendum: On further testing at home against a Hardline tachometer with the same KombiEngine, my suspicion that this tachometer was being affected by the KombiEngine “rev limiter” was confirmed. As both tachs started providing inaccurately low readings as the engine approached its max RPM of 9,500. It may be that they are semi-accurately reading the pulses to the spark plug, which with a rev limiter and engine running at max RPM would be less than the actual engine revolutions per minute.Based on this, the usefulness of the wired clamp that I can also use with the Hardline Tach (a similar clamp would cost $6-7 by itself), and that this tach was accurate enough in induction mode, I’ve decided to keep it and have cancelled my return. Seems it may come in handy as an induction tach, and as a secondary tach for RPM validation purposes. In that case I’d say it’s worth the $16-17.I have not tested it for RPM’s over 9,500.I minus one star for the instruction shortcomings and the lag in RPM reporting relative to the Stihl and Hardline tachs.

Great tool I never knew about. Easy to use and the display has large numbers and high contrast making it easy to read. Seems accurate but no way to really tell for sure without having another one to check it against but I feel confident it is working as it should.

Works as intended.

Did work rpms all over the place sent back.

I'm very pleased with the tach. Just with the lawnmower so far.

Useful for small engine repair and maintenance. Not sure about the durability having just started using it. Very handy.
