Topcon LS-100D LASER SENSOR RECEIVER
It features an extra-wide beam capture sensor that also rejects annoying interference from strobe light exposures. The large and bright LCD displays (front and rear) feature 9-channels of grade information and digitally show the distance to on-grade. By pressing the Hold button, the display is locked so the user can conveniently read the the results. For added versatility, three colored LED's and a strong magnet mount are embedded for vertical operation, ideal for steal erection or operator grade checking while excavating.
To assist in monitoring the Topcon rotating laser, alert icons appear on the LCD if the instrument is disturbed (HI Alert) or when the laser battery is low. |

Why This Equipment
Dual Grade Control
Control two slopes simultaneously for crowns, swales, and complex drainage layouts.
Machine Ready
Pairs with machine receivers for dozer, grader, and scraper grade control.
IP67 Rated
Weatherproof for outdoor use in rain, dust, and construction site conditions.
High Accuracy
±0.1mm/m grade accuracy — holds tolerance through a full working day.
What's In The Box
Continuous grade control. No continuous labor.
Grade stakers cost $50–80/hr and disappear between passes. A dual-slope grade laser installs once and controls your blade automatically — through every cut, every fill, every pass. That's the math that makes grade lasers one of the fastest ROI investments in earthwork.
Professional contractors specify dual-grade systems for a reason: single-grade units work for straight drainage. The moment a job has a crown, a swale, or a complex parking lot slope — you need dual-grade.
Buying from Express Tools means authorized, factory-fresh inventory, legitimate firmware, and technical knowledge when you need it.
