In an experiment, the angles are required to be measured using an instrument. 29 divisions of the main scale exactly coincide with 30 divisions of the vernier scale. If the smallest division of the main scale is half-a-degree \( \left(=0.5^{\circ}\right) \), then the least count of the instrument is
(1) one minute
(2) half minute
(3) one degree
(4) half degree
