If your isn’t ideal in adjustment, the resulting line of sight will be inclined in the event the bubble is at the centre.It will involve measuring the angle of elevation between the two factors and employing trigonometry to calculate the real difference in elevation.As opposed to immediate leveling, which relies on the use of leveling devices and
