Which tach is better, this analog tach
Actron CP7605 Dwell/Tachometer/Voltmeter Analyzer

or this digital tach?
Actron CP7677 Automotive TroubleShooter - Digital Multimeter and Engine Analyzer
Can you please recommend a digital tach?
TIA!
The analog tach was better.

The one built into my Actron digital advance timing light seems like a good combination.
I also have an Actron multimeter with K type input, reads dwell/PW/RPM etc, but it has issues in that it cannot read the AC component (noise) on a DC signal like a "real" meter should, and it's not true RMS.
Mines a few years old, so they may have solved that stupid problem, IIRC mine ws ~$80 years ago.

I bought a digital Actron Digital Multimeter CP7678 on ebay.
It measures RPM and a lot of other things.

Mine an older yellow Actron 100 series, K type TC. inductive pickup etc.
IIRC it was only ~$90 at the time, apparently they are little more these days...

I have a similar featured digital timing light from Actron, toggles from timing to RPM on the fly, very easy.
