I'm gonna buy a boost guage but have come across some that have a range I'm not familiar with.

Some of these offer a range where the needle goes from X in Hg to 0 to X PSI.

Would having this 'dual' range type guage be of ANY benefit to me?

I figured on just getting a 0-15 PSI guage and being done with it.
