BOSCH GLM400CL Outdoor Laser Measure up to 400 Foot with Bluetooth

Measure Further, Document Faster on Any Job Site

The Bosch GLM400CL BLAZE Outdoor 400ft Laser Measure delivers professional-grade distance measurement capability in full daylight conditions where standard laser measures fall short. Equipped with an integrated zoom camera, Bluetooth connectivity, and seamless MeasureOn app support, the GLM400CL transforms raw distance data into organized digital documentation — eliminating manual note-taking and reducing costly remeasurement. Whether you're shooting across a construction site, measuring building facades, or staking out property boundaries, this tool keeps up with your pace.

Built for Outdoor Jobsite Demands

Traditional laser measures top out around 100 to 200 feet and struggle in bright sunlight. The GLM400CL pushes that ceiling to 400 feet with a green laser engineered for outdoor visibility, combined with a camera viewfinder that lets you aim precisely even when the dot isn't visible to the naked eye. The result is a measurement workflow that works as well outside as a tape measure works up close — without the second person, without the errors, and without the wasted trips back and forth.

• IP54 Protection: Sealed against dust and water splash for full outdoor use in varied conditions
• Backlit Display: Readable in low-light conditions during early morning or late-day work
• Compact and Pocketable: Under 6 oz. with a belt-clip-ready profile for all-day carry without fatigue

Job Site Applications

General Contractors & Site Supervisors: Shoot across an entire lot to verify setbacks, confirm building dimensions from foundation to roofline, or check elevation grades — all from a single position without needing a second crew member to hold a tape.

Estimators & Pre-Construction: Walk a site solo and capture room dimensions, facade lengths, and ceiling heights directly to the MeasureOn app. Annotate images in real time and send a complete measurement report before leaving the property.

Surveyors & Land Development: Use the 400ft range to measure across roads, drainage channels, or property boundaries that physically block a tape measure. The camera viewfinder provides targeting confidence across distances where laser visibility is limited by ambient light.

Remodeling & Restoration Contractors: Calculate square footage, material quantities, and opening dimensions for windows and doors with a tool that stores and transmits data — reducing transcription errors between the field and the office.

Frequently Asked Questions

Does the Bosch GLM400CL work in direct sunlight?

Yes. The GLM400CL is specifically designed for outdoor use. While the red laser dot may be difficult to see at long distances in bright sunlight, the integrated 4x zoom camera viewfinder displays the target with a crosshair overlay on screen, allowing accurate aiming and measurement without needing to see the laser dot directly.

What is the MeasureOn app and does it cost anything?

MeasureOn is Bosch's free companion app available for both iOS and Android. It connects to the GLM400CL via Bluetooth and allows you to capture photos annotated with measurements, organize data by project, and share documentation with clients or your office team. There is no subscription fee required.

What measurement modes does the GLM400CL support?

The GLM400CL supports continuous measurement, addition and subtraction, area, volume, single-indirect (Pythagorean), double-indirect, and combined Pythagorean modes. These cover the full range of standard measurement tasks for both simple distance work and complex geometric calculations on site.

Is the GLM400CL waterproof enough for outdoor use in rain?

The GLM400CL carries an IP54 rating, which means it is protected against dust ingress and water splashing from any direction. It is suitable for typical outdoor jobsite conditions including light rain. It is not designed for submersion and should not be used in heavy downpours or standing water.
