Hand Signals For Your Air Pressure

For PSI, usually thousands are shown on your arm & hundreds with your hands.  For example, to show 2,200 PSI, you would place 2 fingers on your arm, and afterwards with the same hand, hold up 2 fingers.  When using BAR, you can signal everything on your hands.  It’s perfectly okay to use two hands when signaling air pressure, but below are common one handed signals for numbers.  With one hand, numbers 1 through 5 are shown vertically while numbers 6 through 10 are shown horizontally.  Remember, you can always just show your buddy your pressure gauge.
