Laser distance meter Goobay Tools 77834 — 30 m range, 2 mm accuracy, Li-Ion battery

The Goobay 77834 laser distance meter is an ultra-compact measuring tool designed for renovation, workshop and site use. It measures distances up to 30 m with 2 mm accuracy and supports area, volume and continuous measurements. The device features Pythagoras measurement for indirect height and length calculations, a 650 nm laser, a built-in 0.25 Ah Li‑Ion battery and a robust aluminium housing, making it suitable for demanding environments while fitting easily in a trouser pocket.

Advantages

This laser distance meter provides precise measurements to a tenth of a millimetre and offers up to 5,000 measurements per full charge. It supports multiple units (metres, inches, feet), includes a continuous measurement function and Pythagoras mode for indirect measurements, and calculates area and volume to speed up renovation tasks. The aluminium housing increases durability for workshop and construction use, and the device has audio feedback on button press plus automatic switch-off after one minute to conserve battery. A 30 cm USB-C to USB-A charging cable and hand strap are included.

Suitable for

• Measuring room, wall and floor areas during renovation (painting, tiling)
• Calculating volumes for storage space or required building material
• Determining height or distance indirectly using Pythagoras method
• Quick on-site measurements in workshops and construction sites

How to use

Switch on the device and select the desired measuring unit (metres, inches or feet). Aim the laser at the target and press the measurement button to obtain distance readings. Use the area and volume functions to calculate surface and capacity values by taking the required sequential measurements. For indirect height or length measurements, enable the Pythagoras mode and follow the on-screen prompts to capture the necessary reference distances. The continuous measurement mode allows you to move the device while tracking changing distances.

Usage recommendations

For best results, keep the laser aperture clean and steady the device when measuring long distances. Recharge the built-in battery before extended use; a fully charged battery supports up to approximately 5,000 measurements. Avoid direct eye exposure to the laser beam and store the meter in a dry place when not in use.
