DEWALT · DW089LG
Ready to buy
The retained reference is $499 current U.S. retail price. Detector, tripod, pole, spare battery and calibration service 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.
Detector, tripod, pole, spare battery and calibration service are separate. Confirm current stock, exact kit contents, authorized U.S. seller, tax, shipping, return rights and service eligibility before paying.
DW089LG is defended for crews already using DEWALT 12 V who need full-room planes without the cost and controls of the newer high-precision platform.

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.
12V MAX 3 x 360 Green Line 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 plane brightness, 12 v runtime, bracket play, detector use and calibration after drops 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.
Check both 90-degree plane intersections at room scale and inspect the bracket before transferring layout.

DEWALT identifies DW089LG as a long-running DEWALT three-plane green system with a 12 V battery, integrated bracket and hard case.

Class 2 green laser with one horizontal and two vertical 360-degree planes for level, plumb and square intersections 100-foot stated visible range and up to 165 feet with the compatible DEWALT detector; working distance depends on light, target, pulse mode and detector alignment Published accuracy is ±1/8 inch at 30 feet. Check each plane and both perpendicular intersections using the manual procedure before critical work and after impact Pendulum self-levels within about 4 degrees and locks for angled-line work and transport. A locked projected line is not a measured grade and out-of-level safeguards are reduced
Integrated magnetic pivoting bracket, ceiling bracket and 1/4-20 and 5/8-11 threads provide placement options. Detector compatibility and clamp zero must be verified separately DEWALT 12 V MAX rechargeable battery, IP65 debris and water resistance and a stated two-meter drop test; none establishes retained accuracy after an actual fall DEWALT limited-warranty and service conditions apply. Protect the windows, lock the pendulum and isolate a unit that fails checks. Avoid eye-height placement, reflective targets and direct viewing
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 comparison evaluates point, cross-line and three-plane tools by geometry, visible and receiver range, accuracy basis, power, mounts and job fit. It is decision context rather than manufacturer proof for every exact SKU.
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.
GLL300-42GL is the general three-plane interior layout defended alternative at $539 current U.S. retail price.
M12 Green 360-Degree 3-Plane Laser Kit is the m12 three-plane interior layout defended alternative at $649 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.
