Laser distance meter Bosch UniversalDistance 50 — 50 m range, 2 mm accuracy, AAA battery

Bosch UniversalDistance 50 is a compact handheld laser distance meter for straightforward, fast distance measurements up to 50 m. The device measures from 0.05 m and reports results in metres with a stated accuracy of 2 mm. It operates on two AAA (1.5 V) batteries and includes an automatic power-off function after 5 minutes of inactivity. The tool is built for simple indoor layout, renovation tasks and on-site measurements where a reliable, pocketable measuring device is required.

Advantages

The UniversalDistance 50 combines a 50 m measuring range with 2 mm accuracy in a small, lightweight housing that is easy to carry and handle. Measurement start from 0.05 m makes it suitable for close-range tasks as well as longer distances, and the clear metre display simplifies reading and recording results. Battery operation on two AAA cells enables quick battery replacement and widespread availability of power sources. An automatic power-off feature helps preserve battery life during intermittent use.

Suitable for

• Interior layout and furniture placement measurements
• Home renovation and improvement planning
• Quick on-site distance checks for installers and tradespeople
• Measuring rooms, corridors and small to medium outdoor façades (up to 50 m)

When it may not be suitable

This device is intended for quick, general-purpose distance measurement rather than precision surveying; for tasks that require sub-millimetre accuracy or professional surveying certification, specialized instruments should be used. The meter’s maximum range of 50 m and basic feature set mean it may not be suitable for large-scale outdoor measurement, complex area/volume calculation workflows, or applications that require integration with other digital systems.

Key specifications

• Measuring range: up to 50 m
• Minimum measuring distance: 0.05 m
• Accuracy: ±2 mm
• Display units: metres (m)
• Power supply: two AAA (1.5 V) batteries
• Automatic power-off: after 5 minutes of inactivity
• Device type: handheld laser distance meter

How to use

Point the Bosch UniversalDistance 50 at the target surface and press the measurement button to emit the laser and record a distance. Ensure the target surface is reflective enough for the laser to return a clear signal; for best results aim at a contrasting or solid target. Read the measurement value displayed in metres and repeat as needed. Replace the two AAA batteries when the display indicates low power and store the device in a dry location when not in use to protect its optical components.

What to consider before purchase

• Required measuring range — up to 50 m suits indoor and short outdoor tasks
• Required accuracy — ±2 mm accuracy is adequate for renovation and layout, not for precision surveying
• Power type — uses two AAA batteries; consider carrying spare batteries for extended use
• Feature set — basic distance measurements without advanced connectivity or complex calculation functions

Usage recommendations

For consistent results, measure from stable positions and aim at a defined point or marker; avoid highly reflective or transparent targets. Use short, repeated measurements to confirm values in cramped or cluttered spaces. Keep spare AAA batteries and a small protective case to maintain the device ready for frequent on-site use.
