Ready to buy
The retained reference is $1,999 current U.S. retail price. Machine control, survey control, replacement receiver, formal calibration and layout labor are separate. Verify line geometry, range conditions, mounts, included accessories, laser class, inspection procedure, authorized seller, warranty and return rights before purchase.
Current market
Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.
Machine control, survey control, replacement receiver, formal calibration and layout labor are separate. Confirm current stock, exact kit contents, authorized U.S. seller, tax, shipping, return rights and service eligibility before paying.
DW079LG is defended when a trade crew needs a complete green rotary kit for interior visibility, receiver-based exterior work and controlled manual slope.

What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
20V MAX Green Rotary Laser was checked against exact identity, current U.S. price, geometry, laser class, range conditions, accuracy basis, leveling and slope, mount and detector compatibility, power, durability, calibration, service, safety and outcome boundaries, independent professional evidence and bounded operator reports.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner and operator discussion returns to green visibility, receiver response, tripod and rod kit, slope setup, calibration and repair cost rather than a universal accuracy, durability or productivity result.
These are self-selected reports from different units, distances, light, surfaces, weather, mounts, receivers, rods, batteries, drops, calibration histories, crews, sellers and service channels. They identify setup and inspection questions and do not establish accuracy, calibration retention, reliability, safety, failure rates, grade, level, plumb, square, productivity or finished-work outcomes.Self-selected operators discuss visibility, mounting, detector use, calibration checks, drops, batteries and service. Reports vary by distance, light, surface, setup and tool history and do not establish accuracy or reliability rates.
Treat the included accessories as a system and prove both axes against a protected benchmark before grade work.

DEWALT identifies DW079LG as a premium DEWALT green horizontal and vertical rotary system with receiver, remote, tripod, grade rod and 20 V battery.
$1,999 current U.S. retail price was retained for DW079LG. Machine control, survey control, replacement receiver, formal calibration and layout labor are separate
Class 3R green rotating horizontal or vertical plane with plumb reference and scan modes; the higher class requires controlled jobsite use Up to 2,000-foot stated working diameter with included detector, while green visibility and scan modes serve shorter interior work. Weather, speed, target and receiver setup govern practical use Published level accuracy is ±1/16 inch at 100 feet. Run the manual horizontal calibration check on both axes and the vertical check after transport, shock or temperature change Automatic self-leveling with selectable manual single- or dual-axis slope and alert mode. Manual slope is not a percent-grade readout and must be tied to known elevations
5/8-11 mounting with included tripod, wall bracket, grade rod, detector and clamp. Stabilize the tripod, verify rod units and detector reference, then protect the benchmark 20 V MAX rechargeable pack, IP67 construction and stated two-meter drop test; receiver, remote and accessories have their own exposure and battery boundaries DEWALT limited warranty and service terms have conditions. Class 3R requires trained control, warning signage, shutter or power-off when unused and no direct or reflected beam exposure. Green glasses are visibility aids, not certified protective eyewear
FDA explains that Class 2 visible lasers depend on the aversion response and that Class 3R direct viewing can be hazardous. Product class does not make deliberate viewing or aiming at people acceptable.
OSHA construction rules require qualified operators, warning placards, shutter or power-off when unused, no direction at employees and positioning above head level where possible.
Professional field review covers the exact DW079LG kit's green beam, detector range, slope controls, accessories and durable housing. Field experience is not a survey-grade or calibration guarantee.
Self-selected operators discuss visibility, mounting, detector use, calibration checks, drops, batteries and service. Reports vary by distance, light, surface, setup and tool history and do not establish accuracy or reliability rates.
REVOLVE2000 GRL2000-40HVK is the complete horizontal and vertical rotary layout defended alternative at $1,049 current U.S. retail price.
M18 Red Exterior Dual Slope Rotary Laser Kit is the exterior dual-slope rotary grade layout defended alternative at $1,399 current U.S. retail price.
Manufacturer identity, exact manual or support documentation, current U.S. price, independent professional decision evidence and bounded owner or operator evidence were checked on August 19, 2026. This desk covers complete current U.S.-supported point, line, plane and rotary laser layout systems used by trades and serious construction buyers. A detector, receiver or remote is part of the counted system only when bundled with the exact kit or intrinsic to its working method; otherwise it remains a separately priced compatibility boundary. The desk excludes bubble levels, laser distance meters, surveying total stations, unsupported marketplace devices, bare accessories, cosmetic bundles, minor color or battery-pack padding and duplicate tool-body or kit variants without a material system difference. Laser class, color and visual brightness do not establish useful range, accuracy or eye safety. Visible range and detector-assisted radius or diameter are separate claims that vary with light, weather, target, rotation speed and setup. Published accuracy belongs to a named geometry, distance, axis and condition and is not a calibration certificate. Points, lines, plane intersections, plumb, square, rotary axes, mounts, receiver zeros and rods can require separate checks. Self-leveling compensation, manual lock, fine rotation, automatic alignment and single- or dual-axis slope are different functions. Manual or receiver-guided slope does not import a design grade or establish survey control. Tripod stability, magnetic hold, clamp reference, thread compatibility, benchmark protection, battery state, ingress and post-impact checks remain operator duties. IP and drop claims do not guarantee retained calibration or cover open battery doors, all accessories, immersion or continued use after a fall. Follow the exact manual, FDA labeling and applicable OSHA construction-laser practice. Use qualified operators, warning controls, beam shutters or power-off when idle, and keep direct and reflected beams away from people and vehicles. Visibility glasses are not protective eyewear. Use manufacturer repair or calibration service when a field check fails and do not open the optical system. No construction laser guarantees code compliance, survey-grade control, grade, plumb, square, level, finished appearance, rework avoidance, productivity, safety or any job outcome.
