Brunton Pocket Transit, Instruction Manual

Page: 2 / 15

Congratulations on your purchase of the finest pocket transit instrument in the world.
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, inclina-
tion 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
temperatures, store in its case and the Brunton
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)
1.2 Protecting The Mirror
While in storage, Brunton recommends placing
the pocket transit in the case, with the base
against the closing snap. (Fig 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 nee-
dle points ( white tip - 2001, 2061, 5005LM and 5006LM models, or “ N ” tip - 5007, 5008 and
8700 Com-Pro models). (Fig 3)
With the small sight toward the object, read azimuth directly where the south end of the nee-
dle points (
black tip - 2001, 2061, 5005LM and 5006LM, or “ S ” tip - 5007, 5008 and 8700
Com-Pro models). (Fig 4)
Detailed explanation of sighting an azimuth is in section 4.
Orientation provides a description of important 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.
