TOUGH - LIGHTWEIGHT - VERSATILE
LaserLine's Optical Grade Rods are the number one seller in the USA, and there's a reason - Tremendous Quality. Tough, lightweight, and versatile, these direct reading (lenker style) rods bear the true test of quality in the field, and hold up exceptionally well.
Optical Version Direct Reading/True Elevation Rod:
Is 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.
Direct Reading, or True Elevation (also known as Lenker style) is a Grade Rod with a moveable tape face. This allows 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.
