Topcon RL-H5A Self-Leveling Laser PS.RB Kit with LS-80L Receiver, Rechargeable Batteries, Measuring Rod INCHES and Tripod

Overview

The Topcon RL-H5A Self-Leveling Laser PS.RB Kit (1021200-06-K2) delivers horizontal and vertical leveling for general construction, concrete work, and interior finish applications. This complete package serves contractors running multi-day projects who need rechargeable power, inches-marked measurement capability, and detection range extending to 800 feet diameter. The kit pairs Topcon's reliable RL-H5A laser head with the LS-80L receiver, alkaline/rechargeable battery options, tripod, and inches-graduated measuring rod—eliminating conversion calculations and providing immediate operational readiness. Designed for concrete contractors, framing crews, and mechanical trades working from imperial-unit drawings, this configuration reduces battery procurement cycles while maintaining the accuracy and durability expected from Topcon's construction laser platform.

Frequently Asked Questions

Can the RL-H5A be used for single-axis slope work like drainage grading?

Yes. The RL-H5A features manual axis slope capability, allowing you to set grade using the fine-adjustment controls on the laser head. The receiver provides audio feedback as you move along the slope path. For dual-axis slope applications, consider upgrading to the RL-SV2S model with electronic slope control.

What's the detection range difference between sunny and overcast conditions?

With the LS-80L receiver, expect 800-foot diameter range in overcast or indoor conditions. Bright sunlight reduces effective range to approximately 400-500 feet diameter. Using laser-enhancing glasses or working during dawn/dusk hours extends outdoor performance. The receiver's sensitivity settings optimize detection based on ambient light conditions.

How does the rechargeable battery runtime compare to alkaline D-cells?

Alkaline D-cells provide 100+ hours of continuous operation, while the DB-74 rechargeable pack delivers 60+ hours per charge. The rechargeable option eliminates battery purchasing costs after 3-4 charge cycles. Many contractors keep both battery holders charged for uninterrupted multi-day projects, swapping packs during lunch breaks.

Is the included tripod height sufficient for excavation depth checking?

The kit tripod extends to approximately 5.5 feet, adequate for most residential foundation and flatwork applications. For deeper excavation monitoring or working over obstruction height, an elevating tripod extending to 8+ feet provides better line-of-sight. The laser's 5/8×11 mounting thread accepts all standard survey tripods.
