    Time Sight usage
    From: Henry Halboth

    While on the subject of the Time Sight, I attach a demonstration of its use as a Hydrographical Survey tool. The attached sights were taken on February 23, 1949, to verify the position of Cape Coast Castle Lighthouse, on the West Coast of Africa. According to the 1938 edition of Bowditch the LH was located in Lat 5-06 N, and Long 1-14 W.
