Elevation / Height Difference
•The SDL30/50 calculates height difference between backsight (BS)
and foresight (FS).
• Elevation of foresight can be calculated by inputting BS elevation.

1. Measure the staff on the ground point A.
2. Measure the inverted staff set on B.
Height Measurement
•Two measurements provide the height of point B.
• Elevation can be calculated by inputting BS elevation.
1. Input the design height difference H.
2. Measure the BM.
3. Measure A and Cut/Fill value is displayed.
