DNA10 and DNA03 digital levels provide accuracy from 0.01 to 0.04 inches per 0.6 miles. Measuring height differences and performing line leveling and stake-outs is quick with the measure-and-record function. Data automatically transfers to a personal computer via a PDMCIA card or a direct RS232 connection. Standard software configures the units, creates code lists and stake-out-height lists, and maintains system software. Users can also create custom output formats. The levels have a large, bright eight-line display.
