Convenient and accurate laser rangefinder
Our school requires teachers to lead students to learn to measure distance with a laser rangefinder, so I bought Tool.com and it is very simple to use. I only need to turn on the switch and place it on the ground to know the distance in the middle, and the distance will be clearly displayed on the instrument, which is very convenient and accurate. I demonstrated the operation process to the students, and they all remembered it, and now they can do it by themselves.
