These levelling staffs used with dumpy levels, otherwise known as autolevels, are used worldwide for setting out levels and are an essential part of survey equipment. They are light duty and extend to 5 meters. They telescope down to 1.25m to fit in your car or bakkie. There levelling bubble is either permanently attached or loose. This bubble is used to hold the staff upright and level, which is particularly difficult in South Africa. We hold spares for the builders staff at Survey Instruments Western Cape. Roadbuilding also requires many of these units.
