with storage and display box $248.95
This is a solid brass reproduction of a Dumpy Level, also known as an Engineer's Transit.
A dumpy level is an optical instrument used in surveying to transfer, measure, or set horizontal levels.
The level instrument is set up on a tripod and then accurately set to a leveled condition using the spirit level and leveling screws.
The operator looks through the eyepiece of the telescope while an assistant holds a tape measure or graduated staff vertical at the point under measurement. The instrument and staff are used to gather and/or transfer elevations.
Measurement generally starts from a benchmark with known height determined by a previous survey,
or an arbitrary point with an assumed height.
Azimuth readings are taken using the internal magnetic compass.
The instrument has an impressive level of quality and craftsmanship.
This dumpy level stands 4 3/4 inches (12.1 cm) tall, 6 inches (15.2 cm) long,
and weighs a very solid 3 pounds 3.6 ounces (1.46 kg).
The Dumpy Level has a 5-power inverting telescope and a focusing adjustment.
The telescope has a removable brass lens cap to protect the large 1.5 inch (38 mm) diameter objective lens.
