DL-500 tracks the RAB Code staff waved back and forth, and
automatically reads the correct height.
The staff reading becomes the minimum when it stands vertically.
The DL-500 automatically finds the least value of staff readings.
This world's first technology allows for error-free readings of
waved staffs, while dramatically reducing operator's eyestrain
