What is more accurate , the fozgometer or the diplay of the oscilloscoop


Would like to know sure about the azimuth of the cartridge ,a visual check first ,than the result of the fozgo , just a bit differance between the left and right channel , than both channels in mono , green led and a little shiny of the red led for the right side .Than looking at the display of my techtronix dual beam oscilloscoop , both channels 
even , no differance in amplitude . Playing a piece of music , perfect ! What is true ? Can you adjust your cartridge with the fozgo with results in the description ? Ofcourse I did the calibration of the fozgo.

Thanks Folkfreak,I enjoy reading older threads,lots of good info out there. Appreciate the answer.

extremely old thread but as a rookie Im jumping in. My results have been the same as others.  I can eyeball it to what  i think is as accurate as possible. starting with a Mirror, level, etc.    But, the FOZGOMETER fine tunes it even more and it sounds better too. no need for microscopes or any of that mumbo jumbo.  It measures better and it sounds better too.   Im a a measurements matter kind of guy though and with the fozgometer i can see it balance out and i can hear it too. Its always not far off from my best attempts at eyeballing it. but it is always an improvement.   thats probably why speaker builders measure things too.     BOOM
