A 7"x 10½" Apollo 15 lunar surface bearing determination guide for use on the lunar surface. It consists of a heavy 8" diameter dial mounted on a thick, heavy card, and comes with a built-in flip up aim guide. This device was used in training the Apollo 15 moonwalkers only. Since on the lunar surface it is difficult to determine direction and distances accurately with the naked eye, this device was used to plan a traverse away from the Lunar Module and to safely return, and it is equipped with lunar shadow data as well. It is dated 6-18-71 and the dial can be rotated to the exact positions of landmarks such as Hadley Delta, Mount Hadley and Bennett Hill. Used no doubt by Scott and Irwin in training in the field outside the Crew Taining Building at KSC. It is faded light brown all around due to the glue used to make it, and much of the glue has released. The paper on the back has separated from the heavy cardboard base, but can be easily reattached. An extremely rare piece of lunar equipment. Estimated Value: $200 - $300
