The LS-B Series of machine-mounted laser sensors are affordable grade indicate systems designed to improve grading and excavating production and accuracy. Easy to use with fast setup, these depth control sensors can be mounted to your earthmoving machines in minutes. Attach any of the LS sensors to a piece of equipment, turn it on, bench in, and go to work. No more waiting for a grade checker or jumping off a machine to check your own grade. With Topcon’s laser sensors, you’ll know if you are above, below, or on-grade all the time. Put the LS-B Series laser sensor on a dozer, then move it to your excavator and then onto a grader. Because it’s quick to move and convenient to use, contractors often want to equip all of their earthmoving machines with these production-boosting control systems.
