RPM info needed

I have used them, would like to get one, thanks fo the link, they are VERY VERY acurate.. I was using my Mac mutimeter with an inductive pickup for comparison.

Those that I save seen are very difficult to get an accurate reading at the top end as the scales are non-linear. On my example above of blower tuning, I don't think I could use a vibration type meter...

Won't/cant argue that. Let me rephrase, they are very acurate for what they are desinged for, lawn mower type engines. They work great at around 3600 rpm. Better?
