Topcon RL-SV2S Self-Leveling Dual Grade Laser DB Kit with LS-80L Receiver and Alkaline Batteries

Professional Dual Grade Laser Kit Built for Demanding Jobsites

The Topcon RL-SV2S DB Kit delivers the dependable dual-grade performance contractors rely on for grading, paving, and site prep work — packaged with the LS-80L standard receiver and an alkaline battery system. Designed for professionals who need consistent, repeatable grade control without the complexity of proprietary power systems, the RL-SV2S DB configuration is a practical, fleet-friendly choice that pairs seamlessly with existing Topcon equipment on multi-machine sites.

Product Overview & Jobsite Applications

The RL-SV2S is Topcon's self-leveling dual-grade rotating laser, engineered to handle slope work in two axes simultaneously — making it ideal for parking lot grading, roadway subbase prep, drainage swale layout, and agricultural land leveling. The DB (Dry Battery) package uses standard alkaline batteries, eliminating the need for dedicated charging infrastructure on remote or off-grid jobsites. The LS-80L receiver delivers reliable grade detection in bright outdoor conditions, and its rugged housing stands up to the rough handling common on active construction sites.

Job Applications

Parking Lot & Flatwork Grading: Set precise dual-axis grades for proper drainage across large paved surfaces. The RL-SV2S handles simultaneous X and Y slope settings, reducing setup time on complex grade layouts.

Road Base & Subgrade Prep: Establish consistent crown or cross-slope references for motor grader and dozer operators working on highway and subdivision road construction.

Drainage & Utility Trenching: Maintain accurate fall rates for storm sewer, sanitary, and irrigation pipe installations where grade tolerance is critical to system performance.

Agricultural Land Leveling: Apply controlled slopes across large fields for irrigation efficiency — the long-range capability and alkaline power system make extended outdoor operation practical without power hookups.

Frequently Asked Questions

What is the difference between the RL-SV2S DB and the standard RL-SV2S kit?

The DB designation stands for Dry Battery, meaning this kit uses standard alkaline batteries instead of a rechargeable battery pack. It is otherwise the same RL-SV2S laser unit. The DB configuration is preferred on remote sites or by crews who want to avoid managing dedicated chargers across a large equipment fleet.

Can the LS-80L receiver be used with other Topcon rotating lasers?

Yes. The LS-80L is compatible with a wide range of Topcon rotating laser levels, making it a practical choice for contractors running multiple Topcon units on the same site. Check your specific model's compatibility documentation to confirm receiver pairing.

What grade range does the RL-SV2S support?

The RL-SV2S supports dual-axis grade settings of up to ±10% on both the X and Y axes simultaneously, covering the vast majority of grading, paving, and drainage applications encountered in commercial and civil construction.

Is the RL-SV2S DB Kit suitable for use in rain or dusty conditions?

Yes. The RL-SV2S carries an IP66 ingress protection rating, meaning it is protected against powerful water jets and heavy dust intrusion. It is designed for active construction environments and can handle typical jobsite weather exposure.
