Why Choose the LAOLAU Laser Rangefinder?

📋 30-Set Automatic Data Storage

Stop juggling a pen and notepad on the job. Every measurement is automatically saved to the device's built-in memory. Press the STO key at any time to instantly recall the last 30 recorded measurements — no re-measuring, no transcription mistakes, more time to get the job done.

📐 Built-In Area, Volume & Pythagorean Calculations

No mental math required. Measure length and width for automatic area + perimeter results. Add height for instant volume calculations. Use the Pythagorean (indirect measurement) mode to determine heights or distances that can't be reached directly — the device does all the math for you.

💡 Backlit LCD Screen for All Lighting Conditions

The bright backlit digital display ensures clear, easy reading whether you're working in a dimly lit basement or a sun-drenched outdoor site. No more squinting at faded tape measure markings.

🔋 Auto Shut-Off for Extended Battery Life

The device powers off automatically after 3 minutes of inactivity, conserving battery so it's always ready when you need it. Requires 2 × AAA batteries (not included).

📏 Dual Reference Points

Seamlessly switch between front-edge and rear-edge measurement reference points for total flexibility — measure from a wall corner or from the back of the device with equal ease.

🌊 IP54 Dust & Splash Resistance

Rated IP54, this rangefinder stands up to dusty construction environments and light moisture exposure, keeping you measuring reliably in real-world conditions.

Frequently Asked Questions

Q: What laser colors are available and what range does each model cover?

A: The LAOLAU laser distance meter is available with a red laser in 50M, 100M, and 200M range models, and with a green laser in 50M and 120M range models. Green laser beams are generally easier to see in bright outdoor conditions. Choose the model that best matches your typical working distance and environment.

Q: Does the LAOLAU rangefinder automatically save my measurements?

A: Yes! Every measurement is automatically stored in the device's internal memory. You can hold up to 30 sets of measurement data and recall any of them at any time by pressing the STO key — no manual note-taking needed.

Q: Can this laser distance meter calculate area and volume automatically?

A: Absolutely. Simply take the required measurements (length + width for area; length + width + height for volume) and the device calculates and displays the result instantly. It also features a Pythagorean mode for indirect height and distance calculations.

Q: Is the LAOLAU rangefinder waterproof?

A: The device is rated IP54, which means it is protected against dust ingress and light water splashes from any direction. It is well-suited for outdoor job sites and dusty construction environments, though it should not be submerged in water.

Q: What batteries does this laser rangefinder require?

A: The LAOLAU laser distance meter is powered by 2 × AAA batteries, which are not included in the package. Please have batteries on hand before use. The auto shut-off feature (3-minute inactivity timer) helps extend battery life on the job.
