Anybody have experience using these little handheld tachometers to measure motor or wheel rpm? While setting up my dual hubs, I noticed that each hub seemed to be running at different speeds, and one hub was getting hotter than the other. I think I fixed the settings, and got them in sync, but got to thinking that it would be nice to be able to measure and confirm that both motors/hubs are running at the same rpm.
Here is one unit I’m considering buying. Any thoughts?
