In construction operations, laser rangefinders and tape measures are usually used to measure length and distance. The original intention of this design is to integrate the two functions. These two functions can be implemented on the same product, which reduces the carrying cost while ensuring accuracy, and improves the user's work efficiency.
Rangefinder function (for remote measurement)
Tape measure function (close range measurement)
A series of portable tools needed in the whole measuring process.
