UMA 3-1/8 Airspeed Indicator 20-140 MPH
Way off. Reads 20 knots too slow.
WAY off, right out of the box. Read about 30% too low. Confirmed via water manometer check and against a 2nd airspeed indicator (+ GPS) in aircraft. Very disappointing that UMA does not seem to test/calibrate their ASIs before the ship them??? Last time I will buy a UMA gauge.
