Review on 🔧 VIAIR 00042 Digital Tire Inflation Gun: Efficient Pump with 2.5" Gauge and Carry Bag by Floe Rankin

Works as expected. I don't know how good the calibration is as each sensor seems to be a little different. You can use it as an INflator or as a Deflator. Connect an air source to the handle and the trigger will add air to the tire. Disconnect the air source and pull the trigger to deflate the tire. It works great with my CO2 tank, should also work well with an onboard air system or stand alone compressor with pressure cut off. Not compatible with low cost compressors that keep running until you turn off their power switch, as when the trigger is closed air pressure builds up in the hose between the compressor and inflator until either the hose bursts or the valve/seal fails. IDK why the dial is so big looks like the digital counter could be smaller. The dial is at a 90 degree angle to the handle, making storage inefficient. I rotated mine 90 degrees to keep it flatter; I can still read the meter.
