Topcon LS-80L LONG RANGE LASER SENSOR
The Topcon LS-80L Laser Receiver Sensor Detector is able to allow you to have a longer range when using a red beam rotary laser. The unit can be adjusted for either a fine or course band, which will help improve the accuracy. It has an audible notice for the height, to make sure it is adjusted properly. You can select from 11 different channels to display the data on the LCD display.
With a rating of IP-66, the Topcon LS-80L Laser Receiver Sensor Detector is protected against dust and water. The unit is in a rubber case, so it is also protected against dropping it. It will stand up to a variety of job conditions. It can also be mounted with a Holder 6 bracket, so it will be more stable.
The Topcon LS-80L Laser Receiver Sensor Detector runs on two AA batteries. It will run for up to 120 hours, allowing for plenty of work time on the job site. It will also shut down after 30 minutes if it hasn't been used, to help save the battery life. Topcon LS-80L Receiver FEATURES

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.
