    Re: Operation of A-7 bubble sextant
    From: Gary LaPook
    Date: 2011 May 5, 11:54 -0700

    I have attached several images of the A-7 sextant to show its versatility. The fourth from the last shows me shooting an altitude straight in front of me, to the left of the frame. The last three images shows me measuring altitudes in the direction of the camera even though I am looking in the opposite direction. No other sextant allows you this freedom.
