Measuring device for builders, installers, and architects, combining the functions of a tape measure and a laser rangefinder. Inside the casing, which has the shape and dimensions typical of standard tape measures, there is a 5-meter tape marked in both metric measurements and inches. The casing also houses a laser rangefinder, allowing for distance measurements up to 20 meters with a small error margin not exceeding ±1.5 mm. The point of reference when aiming can be the front or back edge of the casing. For displaying measurement results and calculations performed with them (such as area, volume, room height, etc.), the Protester J20 laser rangefinder features a black-and-white display (without backlight).
