Possibly 5 stars once I install and test. Quality and service good. Thank you AS.
Had to return my 0-240 kts UMA 2.25 gauge as it was reading 15 to 25 kts too fast per manometer test. Checked the new one that came in as replacement and it's spot on.
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.
