Cool Altimeter. That's a real one. I used to Remove and Replace those on jets in the military.
You can dial it in by finding out the local barometric pressure from your local airport, and setting that to your actual altitude. In the US, Barometric Pressure is calibrated in Inches of Mercury. 29.92'' [Hg] is standard barometric pressure at Sea Level.
If you set it at 29.92'' you will read your ''Altitude'' above Sea Level. What is Prescott's elevation?
