Bosch Professional GLM 250 VF, from 0.05 to 250 m measurement range, ± 1 mm accuracy, protective pouch, wrist strap, manufacturer's certificate, 4 x 1.5 V batteries (AAA) (tool)
The device has a good accuracy after the first tests. Dealing with it, even with a distance measurement is good. It makes sense at greater length measurement up to 250m, an additional reflector panel eg DIN A4 size. For this I have a film Orafol Refl
