What is a Direct Reading/True Elevation Grade Rod?

The Direct Reading or True Elevation (also known as Lenker style) is a grade rod with a movable tape face allowing you to set the actual benchmark elevation, or any elevation, above or below the bench into the rod. The actual true elevation above sea level is read on these rods, thus eliminating errors caused by adding or subtracting. Since NO math is involved, grade shots are much faster than conventional style rods. There are 16 different models to choose from!
