Topcon RL-SV2S Self-Leveling Dual Grade Laser RB Kit with LS-80X Receiver and Rechargeable Batteries

Topcon RL-SV2S Self-Leveling Dual Grade Rotary Laser

The Topcon RL-SV2S is a professional-grade dual slope rotary laser engineered for contractors who demand precision across demanding grading, excavation, and site preparation projects. Bundled with the LS-80X laser receiver and a rechargeable battery system, this kit delivers everything needed to establish accurate cross-slopes and single-axis grades right out of the box — reducing consumable costs and maximizing uptime on the jobsite.

Overview & Jobsite Applications

Whether you're finishing a parking lot, grading a sports field, laying agricultural drainage, or preparing a building pad, the RL-SV2S provides the dual-axis grade control professionals rely on. Its self-leveling mechanism automatically compensates for minor instrument setup variations, so your crew spends less time fussing with the instrument and more time moving material. The wide ±5% grade range handles virtually every slope scenario encountered in civil and commercial construction.

Job Applications

Site Grading & Earthwork: Set precise cross-slopes and single-axis grades simultaneously, enabling machine operators and grade checkers to maintain tight tolerances across large cut-and-fill operations without repositioning the instrument.

Parking Lot & Flatwork Construction: Establish consistent drainage slopes across concrete and asphalt pours, ensuring proper runoff angles are maintained from edge to edge on commercial flatwork projects.

Agricultural Land Leveling & Drainage: The ±5% dual-axis range is ideal for tile drainage installation and field leveling, where maintaining controlled grades over long distances is critical to crop irrigation performance.

Sports Fields & Recreational Surfaces: Achieve the precise, consistent crown profiles required for athletic fields, golf course shaping, and recreational surface construction where grade tolerances are tightly specified.

Frequently Asked Questions

Can the RL-SV2S set grade on both axes at the same time?

Yes. The RL-SV2S supports simultaneous dual-axis grade, meaning you can establish independent slope values on the X and Y axes concurrently. This is essential for drainage and grading work where cross-fall and longitudinal grade must both be controlled at once.

What is the maximum working range of this laser?

With the included LS-80X receiver, the RL-SV2S has an effective working diameter of up to 800 meters (approximately 2,600 feet), making it well-suited for large open sites. Visibility conditions and ambient light will affect practical detection range.

Does the rechargeable battery system replace standard alkaline batteries?

Yes. The bundled Ni-MH rechargeable battery pack is designed as the primary power source for this kit, eliminating the ongoing cost of disposable alkaline batteries. The included charger restores full capacity between shifts, with runtime up to 60 hours per charge.

Is the RL-SV2S compatible with Topcon machine control systems?

The RL-SV2S is a rotary laser level intended for optical grade control with a receiver and grade rod. For full machine control integration, Topcon offers dedicated 3D and indicate-only machine control systems. Contact our team to discuss the right solution for your equipment.
