I happen to work
VB and BK, and used to work FB. When you check air pressure as much as I do, it pays to spend some $$ and get a Molten Digital Air pressure gauge. It's darn expensive, but it makes the process of checking air pressure very, very easy, and it is small enough to keep in your jacket pocket.
