Topcon RL-SV1S with LS-100D Deluxe Receiver Kit
The Topcon RL-SV1S Single Grade Rotary Laser Kit paired with the LS-100D Deluxe Receiver delivers the precision and reliability that grading contractors demand on demanding jobsites. Whether you are working in harsh sunlight, dusty environments, or tight grade tolerances, this kit gives you the signal detection capability and battery endurance to keep crews productive all day without compromise.
Kit Overview & Jobsite Applications
Designed for contractors who require dependable single-grade accuracy across a wide range of earthwork and site preparation applications, the RL-SV1S operates at a self-leveling accuracy of ±1mm at 10m. The LS-100D Deluxe Receiver extends detection range up to 600m in diameter and features enhanced signal processing that outperforms standard receivers in bright sunlight and adverse weather. Rechargeable battery packs eliminate the ongoing cost and downtime associated with disposable batteries, making this kit a strong long-term investment for busy crews.

Job Applications
Site Grading & Earthwork: The RL-SV1S excels at establishing consistent single-plane grades for mass grading, cut-and-fill operations, and rough grading prior to paving or foundation work. The extended 600m operating range means machine operators and grade checkers can work simultaneously across large sites without repositioning the instrument.
Drainage & Utility Slope Work: Precise single-grade control makes this kit ideal for setting drainage swales, storm sewer lines, and utility trench grades. Contractors can dial in exact slopes and trust the LS-100D receiver to hold grade consistently even when site dust obscures visibility.
Concrete Flatwork & Sub-base Prep: Before pouring slabs or setting sub-base aggregate, the RL-SV1S provides a reliable elevation reference for screeding and compaction crews. The bright audible and visual indicators on the LS-100D keep finishers working efficiently without stopping to read a level.
Agricultural & Land Leveling: For agricultural laser leveling operations, the RL-SV1S single-grade mode and long operating range deliver the coverage and battery endurance needed for large field leveling passes, helping optimize irrigation uniformity and field drainage.

Frequently Asked Questions
- What is the maximum operating range of the RL-SV1S with the LS-100D receiver?
- With the LS-100D Deluxe Receiver, the Topcon RL-SV1S has an operating range of up to 600 meters in diameter, making it well-suited for large site grading, earthwork, and agricultural leveling projects where crews need to work across wide areas without repositioning the instrument.
- Does the RL-SV1S work in direct sunlight?
- Yes. While the RL-SV1S emits a standard red beam that may be difficult to see with the naked eye in bright conditions, the LS-100D Deluxe Receiver is specifically engineered with enhanced signal processing to detect and lock onto the beam reliably in direct sunlight and dusty environments, maintaining accurate grade indication for your crew.
- Are the batteries included and what is the expected battery life?
- This kit includes a rechargeable battery pack and charger. On a full charge, the RL-SV1S delivers up to approximately 100 hours of continuous operation, significantly reducing downtime and eliminating the recurring cost of disposable batteries on long projects.
- Is the Topcon RL-SV1S compatible with machine control systems?
- The RL-SV1S is a single-grade rotary laser designed primarily for manual grade checking with a rod and receiver. For full machine control integration, Topcon offers dedicated machine control laser systems. However, the RL-SV1S can be used alongside grade control equipment for manual verification and layout tasks on the same site.
