A dumpy level is an optical instrument used in surveying to transfer, measure, or set horizontal levels with reference to the mean sea level or available approved datum precisely. The instrument and staff are used to gather and/or transfer elevations (levels) during site surveys.

Measurement generally starts from a benchmark with known height determined by a previous survey, or an arbitrary point with an assumed height.A dumpy level is an optical instrument used in surveying to transfer, measure, or set horizontal levels with reference to the mean sea level or available approved datum precisely.
