What matters most
Questions worth asking
What does accuracy of plus or minus 1/16 inch mean?
It means the measurement can be off by up to 1/16 inch in either direction. That is a tiny margin. For most construction and remodeling tasks, it is acceptable.
Can I use a laser distance meter outdoors?
Yes, but bright sunlight can wash out the laser dot. Models with a camera viewfinder or higher power laser work better outdoors. Some also have a target plate to reflect the beam.
Do I need a camera viewfinder?
If you work outdoors or over long distances, a viewfinder helps you see where the laser lands. For indoor use, it is not essential.
How do I measure with Pythagorean mode?
Pythagorean mode lets you measure a height or distance indirectly. You measure two sides of a right triangle. The meter calculates the third side using the Pythagorean theorem.
Are rechargeable batteries better than AAAs?
Rechargeable batteries save money over time. However, AAA batteries are easy to replace and never run out of charge. Some meters use proprietary batteries, which can be costly.
What is the difference between IP54 and IP65?
IP54 protects against dust limited ingress and water splashes. IP65 is dust tight and protected against low pressure water jets. IP65 offers more protection.
Can I use a laser distance meter for measuring land?
Some long range meters can measure up to 650 feet. That might be enough for small plots. For large land, surveyor tools are needed. Accuracy may vary over long distances.
How do I ensure accurate measurements?
Use the meter on a stable surface. Point the laser at a flat target. Avoid shiny surfaces that scatter the beam. Use a target plate for long distances. Keep the lens clean.
What is the maximum range I need?
For typical interior rooms, 165 feet is plenty. For larger commercial spaces, consider 330 feet or more. For outdoor use, longer range helps. Choose based on your typical tasks.
Are these meters calibrated?
Most are factory calibrated. Over time, calibration may drift. Some manufacturers offer recalibration services. For critical work, check periodically against a known distance.
Our pick
For most users, the Bosch GLM400-20 is the best high-accuracy distance meter. It offers top notch accuracy, a long range, and a clear display. If you need Bluetooth and a compact size, choose the Leica DISTO D2. For outdoor long range work, the Bosch Blaze GLM500 is excellent. If you are on a budget, the Tacklife HD60 provides good value. Ultimately, the right meter depends on your specific needs. But the GLM400-20 delivers balanced performance for a wide range of applications.
