Meaning of Back-staff (Davis Quadrant)

Back-staff (Davis Quadrant) means: A peculiar kind of quadrant formerly used in taking altitudes at sea, so called because the observer turned his back to the sun. Captain John Davis conceived this instrument during his voyage to search for the Northwest Passage. It was described in his Seaman’s Secrets published in 1595. Still in use in the 1700s but being replaced by the octant and sextant. It was difficult to plot the moon, planets or stars with a back-staff. It was used principally in day time with the sun.
