I have always felt a tach is nothing more than an extra gadget.
Unless you are driving a speorts car, a tach is not needed. While teaching my wife to drive a manual, I try to explain to her while driving, you can hear and feel when the engine likes or dislikes an RPM at a given speed. If you are going up hill, your engine should be turning a little faster than if you are going down that hill, and a different RPM when driving on a flat road.
There is no right RPM to be in, just some are better than others.
I have found with her, she is worried about looking at the tach to make sure she is doing it right. Maybe next time, I will cover the tach with a sheet of paper.....hmmmm.
