I do not know if one of the new digital volt meters will fluctuate or not, but I also like the swing needle type volt meter simply not only to show a pending charging situation but I run a headlight modulator most of the time and also most of the time I forget to turn it off in a group ride until I get into the group, so the voltmeter at idle will fluctuate with the modulator, so I can tell if I have it on or off. Simply an indicator and a help. Kit
My Lascar digital does the same thing...........I can immediately tell if I have my Gerbings controller on for my heated gear as it pulses the output (PWM). You can see the fluctuations on the digital voltmeter.
I like digital better as you can immediately see the voltage.........no need to see where the needle is lined up at on like an analog version.
btw - I hardly consider my voltmeter location "worthless". :roll:
