1 -- Important Information
Congratulations on your purchase of the finest pocket transit instrument in theworld. The Brunton Pocket Transit is not just a compass. It combines a surveyor’s compass, prismatic compass, clinometer, hand level and a plumb into a single instrument. Use the Brunton Pocket Transit to measure azimuth (compass bearing), vertical angles, inclination of objects, percent grade, slopes, height of objects and for leveling. Even though all Brunton Pocket Transits are made to be rugged,durable and withstand the rigor associated with outdoor use, care must be taken to assure long-life of your instrument. Avoid impacts, dropping, extreme Small Window temperatures, store in its case and the Brunton Flat Cover Pocket Transit will perform.
1.1 Opening The Pocket Transit Rotate the pocket transit until the flat cover faces up, and the small window is positioned away from you.Unlatch the cover from the base. (Fig 1)

2 -- Orientation
Orientation provides a description ofimportant pocket transit parts. A detailed description of its operation is provided throughout the manual. 2.1 Needle (Fig 5) The needle is induction damped, which allows the needle to seek magnetic north and come to a complete rest in a minimum amount of time, without accuracy degradation. 2

1.3 Direct Reading Why are EAST & WEST switched?

Because the pocket transit is a direct reading compass.Read azimuth directly where the needle points on the graduated circle. With the large sight toward the object, read azimuth directly where the north end of the nee1
