This is our new Tachometer. Don't be fool by other imitation on ebay, they only used the same case! After 1 years of tryout and asking many of our customers about what they think about our product, we finally made new version. This time, we added a recall of the highest rpm! old features are still there: tachometer hour meter with programable maintenance this rpm has been tuned to refresh the display every second! The tach/hour meter is triggered by 5.5 ft shielded wire. The tachometer can goes up to 99,999 rpm and have an error margin of .2% The tachometer is powered by an internal lithium battery (5 years) Installation is very easy! You only need to wrap the tachometer wire around the spark plug wire. No tool required! work on every 2 strokes or 4 strokes engine! ** it must be a spark engine**
