Laser Version Direct Reading/ True Elevation Rods
For use with a laser detector. There is a special
rail slide and Laserline detector bracket that
lets the laser detector travel the full working
length of the rod. This allows faster and easier
readings because it takes the awkwardness
out of having to loosen the detector, move
the detector, then tighten the detector for
each reading.
Optical Version Direct Reading/ True Elevation Rods
Are used with optical instruments and have
no special rail for the laser detector. All tape
faces have large scales and are easy to read at a
distance when using an optical instrument.

HOW THEY WORK:
Direct Reading/True Elevation Grade Rod
Direct Reading, or True Elevation (also known as Lenker style) is a Grade Rod with a moveable 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.
On most jobsites, the bench elevation is typically established by survey, and all elevations on that project are
above that or below primary bench elevation.
EXAMPLE:
In the USA, these elevations are typically represented in feet, tenths and hundredths of a foot as per the example.
Marc Blanden – Cutting Edge Excavation –
These are by far the best grade rods made. we have been using them for 20 years and it is the most logical way of setting grade using true elevations. To much room for error using standard grade rods, making a random number equivalent to an actual elevation number. These things are the best!!!!!!!!!! They are Cutting Edge!
