In Vernier Theodolites, vernier are used for taking the readings. These theodolites are most commonly used in the general works. Most of the general Theodolites can read upto 20"

Transit and non-transit theodolite.
5 mm is the least count of theodolite.
least count of theodolite is 1 second
The least value which can be measured from any measuring instrument or device is called its least count. Generally the least count of a vernier caliper is 0.02mm.You can get a least count of 0.01mm in Digital vernier caliper.
