this picture is the theodolite that i got off the theodolite blog..

this is the the calculations of the feeild book and the totals all add up the same which is 06.08

the differences between the theodolite and the builders level is:

- The builders level is used for shooting heights and gets measurements from a builders rule and its important to make sure the bubble is in the centre.

-The theodolite is used for measurements for both horizontal and verticle angles.

- how too set up a three screw builders level:

set up tripod

sit the level up on top of the tripod the screw it on

then use the three screws too put the bubble in the centre.
