I first played with a laser measuring device in Tech in Asia‘s office where the events team use it to measure event spaces to plan for banners placement. I was amazed at how fast it is to obtain a measurement for a room. After that I never look at measuring tape the same way again.
Not saying that the measuring tape is not useful, I still think it is useful to measure smaller objects. Whereas to measure spaces between walls and pillars, the laser measuring device really excels.
