Reply to "Tachometer"

No telling how many wild goose chases this list has prompted.  I went in the basement looking for my tach pen and found this variation on the tach pen.  Works about the same way but takes both hands to turn the inner and outer dial. You can use the tach pen with one hand. Though I think the scale on this tach is easier to read. While at it I took a shot of the cheap laser tach it is easier to use and more accurate than either resonance tachs. My greatest beef with the laser tach is there is no way to dump the memory and you do need the stripe or a painted disk (flywheel) for the thing to work. It does work well enough for our uses with toy trains.                         j
