Topcon RL-HV2S Self-Leveling Dual Grade Laser RB Kit with LS-100D Receiver and Rechargeable Batteries

True Dual-Slope Performance Built for Professional Grade Work

The Topcon RL-HV2S RB is a professional-grade dual slope rotary laser kit engineered for contractors who need simultaneous X and Y axis grade control without compromising accuracy or runtime. Paired with the LS-100D Deluxe Receiver and a rechargeable battery system, this kit eliminates the cost and downtime of disposable batteries while delivering the precision your crew demands on grading, drainage, and site prep jobs. As an authorized Topcon dealer, Express Tools provides this kit with full factory warranty support and free shipping.

Jobsite Overview & Applications

The RL-HV2S RB is purpose-built for earthwork, civil grading, slab work, and drainage installations where simultaneous dual-axis slope control is non-negotiable. Its ±10% grade range in both X and Y planes allows operators to dial in complex compound grades from a single instrument setup, cutting layout time significantly versus single-grade lasers. The self-leveling system with audible out-of-level alarm keeps the job moving safely, and the IP66-rated housing stands up to dust, rain, and jobsite abuse.

• RC-4 Remote Control — wireless grade and function control up to 200m away
• Carrying Case — heavy-duty molded case for transport and storage
• Operator Manual & Quick Reference Card

Job Applications

Site Grading & Earthwork: Set compound slopes across large pads with a single instrument position. The ±10% dual grade range covers most civil grading tolerances without repositioning, keeping machine operators and rod hands productive.

Drainage & Pipe Installation: Achieve precise fall rates for storm drains, retention ponds, and utility trenches. The LS-100D receiver's grade readout gives your crew real-time depth verification without constant instrument checks.

Concrete Flatwork & Slabs: Use the RL-HV2S RB to establish screeding grades on sloped slabs, parking decks, and warehouse floors where ADA or drainage slopes must be held tightly across large areas.

Agricultural & Land Leveling: The extended 800-meter working radius and IP66 housing make this laser equally capable on large-acreage agricultural leveling projects where instruments take a beating from dust and field conditions.

Frequently Asked Questions

What is the difference between the RL-HV2S and the RL-HV2S RB?

The RB designation indicates the kit includes a rechargeable battery pack and compatible charger instead of standard alkaline batteries. All other specifications and included accessories are identical. The rechargeable system is the preferred choice for contractors running full shifts to reduce operating costs.

Can the RL-HV2S set grade on both axes at the same time?

Yes. The RL-HV2S features true simultaneous dual-slope capability, allowing you to set independent grade percentages on both the X and Y axes at the same time. This is essential for compound grading applications like parking lots, drainage swales, and sloped slabs.

What is the maximum working range of the RL-HV2S RB kit?

When used with the included LS-100D Deluxe Receiver, the RL-HV2S has a working diameter of up to 800 meters, making it suitable for large-scale earthwork and civil grading projects.

Is the Topcon RL-HV2S RB covered by a factory warranty?

Yes. Purchased through Express Tools as an authorized Topcon dealer, the RL-HV2S RB kit is backed by Topcon's factory warranty. Express Tools also provides pre-sale and post-sale support to help you get the most out of your investment.
