After trying an ultrasonic rangefinder, I was amazed at the accuracy of the laser rangefinder with constant measurements to the millimeter. In addition the device exudes strength and good construction. Finally, it is encased in multiple interesting functions: single or successive displayed distance, area, volume, Pythagoras, memory, level bubble. We can blame an instruction manual in English, but not fatal as long as we have sufficient bases. Otherwise it is explained by someone and when taken in hand, the display on the screen is clear enough to do without user guide. I recommend
