Answer:

In stadia system fixed hair method and movable hair method are used to find out horizontal distance.

In tangential system various cases are being used to find out the horizontal distance.

In stadia system a telescope is fitted with stadia hair in movable hair method.

In tangential system a telescope is not fitted with stadia diaphragm.

Two vane or targets are fixed at a known distance apart a normally 3m.

Two target are fixed distance apart is probably 3m to 4m.

In stadia system there is more speed and readings are easily be taken.

In tangential system there is less speed and reading are not easily be taken.

Stadia method with the staff being held vertically is in common use in tachometry.

Tangential method or system is not in common use.
