The Topcon RL-V2S is a dual-function rotary laser that operates in both vertical and horizontal planes. It is used for wall layout, door/window plumb work, and horizontal grade — making it unique among single-axis rotary lasers.
Topcon RL-V2S — Complete Specs, Manual & Guide
Category: Rotary Laser | Brand: Topcon | Model: RL-V2S
The Topcon RL-V2S is a versatile construction laser capable of projecting a horizontal grade plane or a vertical fan plane, giving contractors a single instrument that handles both layout and leveling tasks. It pairs with the Topcon LS-80A receiver and features a robust IP66 housing for use in demanding site conditions.

Frequently Asked Questions — Topcon RL-V2S
What does the Topcon RL-V2S do that a standard rotary laser cannot?
The RL-V2S projects a vertical plane in addition to the standard horizontal plane. This lets contractors use a single instrument for door and window plumb layout, wall partition alignment, and fence post alignment — tasks that would otherwise require a separate optical plumb or a line laser.
What receiver is compatible with the Topcon RL-V2S?
The factory-matched receiver is the Topcon LS-80A. The LS-80L is an upgrade option. In horizontal mode, compatible 635nm red-beam receivers from Spectra Precision (HR320, HR550) also work.
How accurate is the Topcon RL-V2S?
The RL-V2S is accurate to ±10 arc seconds in both horizontal and vertical operating modes, equivalent to ±1/16 inch per 100 feet. This meets the accuracy demands of wall layout, framing, and general grade work.
What is the working range of the RL-V2S?
The RL-V2S has a working diameter of 700m when used with the LS-80A receiver. Range is reduced in direct sunlight; using the receiver shade attachment improves outdoor range in bright conditions.
Can the Topcon RL-V2S do slope or grade work?
No — the RL-V2S is a self-leveling instrument only. It does not support manual grade/slope settings. For dual-grade grading work, consider the Topcon RL-SV2S, which adds X/Y grade capability.
