If you're looking for accuracy when shooting grades and establishing elevations, Electronic Levels are more accurate. They read a bar code specially made and graduated grade rod and the Electronic Level keeps up with the elevations, does the sighting and math for you which increases accuracy. An Electronic Level covers many construction applications as it automatically determines your delta height. Enter your benchmark, measure your back sight, measure the foresight and the result will be displayed instantly. Optical reading is no longer necessary as the bar code on the grade rod determines height and distance which is displayed on a highly visible LCD display. There will be no misreading or human error when reading the rod measurements. Leica manufacturers very high quality products and the Leica Sprinter is no exception. The Leica Sprinter is engineered and built with quality and ease of use in mind.
