Great sensitivity to the price. Sensitivity is listed in the description. My rough measurements are 40 arcseconds per division. Each division is 2 mm, which corresponds to 20 arc seconds per mm. (My measurements consisted of placing a spirit level on a steel rod, adding shims to one end of the rod, and noting how far the bubble moved.)
