Has anyone heard of these? I guess a wire is wrapped around the spark plug cable and when it picks up a current it can show the rpms. I would love to find a nice one. any suggestions?


does it update every 2.5 sec?I got one very similar from Staton inc. it was $35 it works very well !

That looks like the same thing made by a different brand. How often does it update? 2.5 Sec? thst seems too slow. if it does, how do like it?
