Topeak Joe Blow Sports 3 Pump

Hey Folks

I was struggling with a mini pump so bought this pump, works great, very easy to use, i have a question, how accurate is the gauge?

I also have a Topeak digital gauge, it seems pretty close to the pump gauge, is that also accurate?

If you want ultimate accuracy you would only know if checked against a tyre services gauge or good garage as there measuring equipment should be checked and calibrated annually
But if there close to each other they surely won’t be that far out for application
