The driving techniques are very situational. You are never going to use them all at once. You just learn them and learn to use ones you like in the correct situation.
The
scangauge seems similar to the gauge you posted, it just doesn't have as many features (its arguable if the additional features are helpful or not). The SG is also $100 cheaper and can display 4 readouts at once. I suggest taking a look at it.
