I've had a Fast Tach for a couple years with no problems

I bought an oregon analogue tach with low and high rpm settings
,battery condition reader, and automatic off function that runs on 9 volts
and like it but was informed that it probably wasnt very accurate?
any feedback......?

I grew up in the analog meter days and there's something to be said for them. You can get a good idea of the rpm even though it is constantly changing.

720 = 2 Sparks pro revolution
180 = 1 spark each 2 revolutions

should this not be inverse :  720 = 1 spark each 2 revolutions ,,,,???
                                          180 = 2 Sparks pro revolution ???

I just received my new TT20K - tach works well on my stihl-chainsaws MS150TC and MS362 - only when it climbes above 10000 rpm then suddenly the tach is reading 5000 - 6000 rpm while my saw is jelling at 11.000 and +

For measuring idle rpm it works - adjusting high rpm's is not possible as tach won't go farther then 6000 rpm.
Max. rpm recall says one time 11000rpm the other time 16000 rpm...... so not reliable at all. ??? ???

The four cycle lawn mowers and many cars, fire the spark plugs every revolution even though the cylinder itself doesn't actually fire but every other revolution.
